🔒 Section 1: Weekly Security News Summary

Aichi-Nagoya Asian Games Open Under Japan's Largest Security Operation of 2026 — Emperor Attends, Drone No-Fly Zones Imposed

The 20th Asian Games opened on September 19, 2026 at Nagoya City Mizuho Park Athletic Stadium (Paloma Mizuho Stadium), with Emperor Naruhito and Empress Masako in attendance. The National Police Agency is deploying up to 10,000 officers per day for the Games, of whom roughly 3,100 are specially dispatched squads drawn from prefectural forces nationwide, explicitly postured against terrorism and other contingencies. Under the revised Small Unmanned Aircraft Flight Prohibition Act that took effect in July 2026, drone flights were temporarily banned within approximately one kilometre of the ceremony venue and of accommodation used by the imperial couple and visiting dignitaries — the first application of the expanded law to an event attended by the Emperor. Authorities have also stated that AI-assisted threat information handling is being incorporated into the security posture. The Games run through the closing ceremony on October 4.

💡Tips for Professionals:

• Assume airspace deconfliction is now an enforced legal matter, not a courtesy: any client-side drone use for venue reconnaissance, media or photography within 1 km of Games venues, VIP hotels or the imperial party's accommodation is prohibited and will draw police attention. Brief media crews and advance teams in writing before arrival in Aichi.
• Expect saturation policing, vehicle checkpoints and identity verification queues across Nagoya through October 4. Build 45–60 minutes of buffer into every venue arrival, and pre-register accreditation and spectator details in advance — on-site verification is the stated bottleneck.
• A national-scale police surge also means thinning of routine patrol coverage in other prefectures. Residential and office security for principals outside Aichi should not assume normal police response times during the Games window.

Two Members of North Korea's Asian Games Delegation Reported Seeking Asylum in Japan

South Korea's Monthly Chosun reported on September 22 that two members of North Korea's roughly 180-person delegation to the Aichi-Nagoya Asian Games intend to seek asylum in Japan rather than South Korea, and have signalled they do not intend to return home. The magazine attributed the information to a source it identified as an official of Japan's Cabinet Intelligence and Research Office, with a further link to the pro-Pyongyang General Association of Korean Residents in Japan (Chongryon). The individuals' identities and roles within the delegation were not disclosed, and it remains unconfirmed whether the reported approach will result in an actual defection. The Japanese government had not commented as of the report, which fell on a national holiday.

💡Tips for Professionals:

• A defection event inside a Games bubble is a force-multiplier for risk: it draws intelligence services, hostile surveillance, media scrums and potential counter-action into venues and hotels that EP teams are already working. Treat any DPRK-delegation-adjacent venue as an elevated-attention zone for the remainder of the Games.
• Principals with no connection to the story can still be caught in a media or police cordon triggered by it. Maintain at least two rehearsed egress routes from every Games venue and hotel, and confirm that drivers know the alternates without needing navigation input.
• Do not allow team members to discuss, photograph or speculate about delegation movements. Even incidental involvement can result in police interviews that remove personnel from the detail for hours.

NPA and FBI Publicly Attribute ¥1.7 Billion Crypto Theft Campaign to North Korean Group "WaterPlum"

Japan's National Police Agency disclosed on September 18 that a North Korean hacking group designated WaterPlum conducted a cyber campaign spanning more than 100 countries including Japan, stealing cryptocurrency worth approximately ¥1.7 billion. The group infected over 30,000 devices with malware between December 2025 and July 2026 and harvested credentials for roughly 7,000 crypto-asset accounts. The advisory — signed by seven organisations from four countries, including the NPA and the U.S. Federal Bureau of Investigation under a "public attribution" framework — states that the actors posed as corporate headhunters recruiting IT professionals and delivered malware inside files presented as technical assessments. The NPA said supporters resident in Japan supplied computers, servers, identity documents and financial accounts, and that police dismantled that support network. Both WaterPlum and associated DPRK IT workers were assessed to operate under the 313 General Bureau of the Munitions Industry Department.

💡Tips for Professionals:

• The initial access vector is a recruitment approach, not a technical exploit. Advisory, family-office and protective-intelligence staff who maintain LinkedIn or industry profiles are exactly the target demographic. Prohibit opening "technical assessment" or "coding test" attachments on any device that touches client itineraries.
• Protective teams routinely hold the most damaging data in an organisation — schedules, addresses, advance notes, vehicle details. Treat EP laptops and phones as crown-jewel assets: separate work profiles, hardware keys for email, and no personal file-sharing services.
• The confirmed presence of in-country facilitators supplying identity documents and accounts raises the baseline risk in vendor and contract-staff screening. Verify residence status and identity documents for locally hired drivers, agents and venue staff through the employing agency, not by inspection alone.

Takaichi Reshuffles Cabinet on September 17: Security Portfolios Held Steady, New Police Oversight Chair Appointed

Prime Minister Sanae Takaichi launched her reshuffled Cabinet on September 17, 2026, retaining the core of her national-security team: Toshimitsu Motegi at Foreign Affairs, Shinjiro Koizumi at Defense, and Minoru Kihara as Chief Cabinet Secretary. Hanashi Yasuhiro was appointed Chairperson of the National Public Safety Commission — the civilian body overseeing the National Police Agency — also taking the territorial issues, Okinawa and Northern Territories, and consumer affairs portfolios. Kimi Onoda continues as Minister in charge of Economic Security with an added remit covering coexistence policy for foreign nationals. A Japan Innovation Party member, Hiroshi Nakatsuka, entered the Cabinet for the first time under the LDP-JIP coalition. Two days later, Defense Minister Koizumi and U.S. Defense Secretary Pete Hegseth agreed to deepen bilateral security cooperation. An extraordinary Diet session is scheduled to convene on October 5.

💡Tips for Professionals:

• Continuity in the Defense, Foreign Affairs and Chief Cabinet Secretary posts means no near-term change to Japan's security or alien-registration enforcement direction. Corporate security managers can hold existing compliance assumptions through year-end.
• The October 5 Diet convocation will bring a renewed cycle of demonstrations, party-bus sound trucks and police cordons around Nagatachō and Kokkai-Gijidōmae. Add the Diet district to your avoid-by-default routing list from early October, and re-survey approaches to any client office in Chiyoda Ward.
• Ministerial changes reset working-level contacts. If your organisation maintains liaison with the NPA, prefectural police or Immigration Services Agency, reconfirm points of contact now rather than during an incident.

Boy Band Member Arrested in Tokyo for Alleged Assault on a Woman in Kōtō Ward

Tokyo police arrested Shuto Inomata, a 25-year-old member of the group Timelesz, on September 19 on suspicion of assaulting a woman in her twenties. He is alleged to have struck the victim in the face on the evening of September 18 in a parking lot adjacent to a convenience store in Tokyo's Kōtō Ward; the woman is believed to have suffered minor injuries. She sought help inside the store, after which staff and bystanders called police. Inomata denied the allegation, telling investigators his hand made contact during an argument. He joined the group in February 2025 after an online audition.

Source: The Japan Times

💡Tips for Professionals:

• Celebrity protection failures in Japan increasingly occur in unmanaged private time — convenience-store car parks, late-night transitions, personal relationships — rather than at controlled venues. Agency and label security managers should review whether coverage genuinely spans off-duty movement or stops at the venue door.
• Bystander intervention and immediate police notification is now the default in urban Japan. Any incident involving a protected person will be reported within minutes and is effectively un-manageable after the fact; prevention and early extraction are the only levers.
• Build an agreed, rehearsed protocol for interpersonal-conflict situations involving a principal: the protective role is separation and withdrawal, never adjudication. Document the protocol so that team members are not improvising under reputational pressure.

Immigration Services Agency to Embed Officers in Ministry Site Patrols Against Illegal Foreign Labour

The Immigration Services Agency of Japan announced plans, reported September 22, to deepen cooperation with other ministries in its campaign against unauthorised foreign employment. From as early as October, agency officials will accompany Ministry of Land, Infrastructure, Transport and Tourism inspectors on patrols of demolition and construction sites, with follow-on administrative guidance and enforcement. The agency is also coordinating with the Environment Ministry over outdoor scrap and waste-plastic storage yards, and with the agriculture ministry over seasonal farm labour. More than 70% of foreign nationals subject to deportation procedures last year were found to have worked illegally. The measures follow the Justice Ministry's "Zero Illegal Immigrants" plan unveiled in May 2026. Foreign residents are legally required to carry residence cards at all times, and immigration officers — unlike municipal inspectors — may demand their presentation.

Source: The Japan Times

💡Tips for Professionals:

• Foreign EP operators, advance staff and support personnel working in Japan must carry residence cards or passports with the correct status of residence at all times. Enforcement encounters are becoming more frequent and more assertive, and a status irregularity will remove a team member from duty immediately.
• Confirm that any locally contracted labour touching a client's property — security guards, facility contractors, event build crews, logistics staff — is engaged through a vendor that documents work authorisation. Liability and reputational exposure now flows to the engaging party.
• Short-term visitors performing paid protective work in Japan without the appropriate status remain exposed. Structure engagements so that the Japanese licensed provider holds the operational role and visiting specialists work in an advisory or liaison capacity.

Rising Foreign-Driver Crash Numbers Prompt Nationwide Road-Rules Awareness Push

Japanese authorities and expressway operators are expanding public-information efforts aimed at foreign drivers as inbound tourism and the foreign resident population grow. In 2025 there were 587 crashes causing serious injury or death in which a foreign driver was wholly or mainly at fault, up from 392 in 2015. Reported problems range from minor infringements — wrong-side driving, misread signage, unfamiliarity with priority rules — to fatal collisions. The awareness campaign coincides with the Autumn National Traffic Safety Campaign, which runs nationwide from September 21 to 30, with September 30 designated as the day targeting zero traffic fatalities.

Source: The Japan Times | Cabinet Office / Government of Japan

💡Tips for Professionals:

• Do not place visiting protective drivers behind the wheel in Japan. The combination of left-hand traffic, narrow urban carriageways, unfamiliar priority conventions and heavy enforcement produces exactly the failure profile in these statistics. Use licensed local drivers and reserve visiting team members for the protective role.
• Enforcement density is elevated through September 30. Expect roadside checks for seat belts, mobile-phone use and alcohol, particularly at dusk. A stop mid-movement is a protective failure in itself: brief drivers on documentation, and ensure vehicle papers and insurance certificates are carried.
• Verify that any driver supplied by a vehicle vendor holds the correct professional licence class and that the operator is a properly registered hire-and-reward business. Ride-hailing or private arrangements may leave the client uninsured in a collision.

Final Verdict Delivered in Tokyo Olympic and Paralympic Bid-Rigging Case

The Tokyo District Court on September 16 sentenced Masao Umino, former president of event management firm Same Two, to 18 months' imprisonment suspended for three years over bid-rigging connected to the 2021 Tokyo Olympic and Paralympic Games; the company was fined ¥150 million. With this ruling, all six companies charged in the case have been found guilty at district-court level. The court found that between roughly February and July 2018, Umino had pre-determined which firms would win planning and operations contracts for the Games and their preceding test events, in collusion with a former deputy head of the organising committee and others. A ¥300 million fine against Dentsu Group is final; four other companies have appealed.

Source: The Japan Times

💡Tips for Professionals:

• The case is a reminder that major-event security and operations supply chains in Japan have a documented collusion history. Where a client is procuring event security, transport or venue operations, insist on competitive, auditable tendering rather than accepting an organiser-nominated vendor.
• Integrity failures in the operations layer create protective risk: rigged awards concentrate work in firms selected for relationships rather than capability, which shows up as under-resourced accreditation, screening and crowd management on the day.
• With the Asian Games running now and the Asian Para Games to follow, expect heightened prosecutorial and media scrutiny of event contracting. Ensure your own subcontracting documentation would survive disclosure.

🌏 Section 2: Japan–Foreign Nations Tension Monitor

1. North Korea — Tension Level: High

North Korea maintained an elevated launch tempo against Japan's periphery during the reporting week. On September 20 the Ministry of Defense assessed that a projectile launched from North Korea's east coast was a ballistic missile, reaching an apogee of roughly 60 km and flying approximately 440 km before falling outside Japan's exclusive economic zone; a second apparent ballistic launch followed the same day. The September 20 activity came eight days after a salvo of short-range ballistic missiles into the same waters, and coincided with the conclusion of the multinational Freedom Edge 26 exercise. On September 22, state media reported that Kim Jong Un, accompanied by his daughter Ju Ae, had overseen the test of a "new-type weapon" two days earlier, widely assessed as a hypersonic missile and glide vehicle intended to defeat missile defences. Separately, the NPA's joint attribution of the WaterPlum cryptocurrency campaign (Section 1) and reports of two delegation members seeking asylum during the Asian Games add cyber and counter-intelligence dimensions to the same actor.

💡Tips for Professionals: J-ALERT activates nationwide on confirmed launches, and a launch during a movement will generate simultaneous mobile-network congestion, rail stoppages and crowd confusion — rehearse a comms-degraded rally procedure rather than relying on phones. Ensure every team member has J-ALERT and NHK World push alerts enabled in English on all devices, and that hotel and venue shelter-in-place options along the Sea of Japan coast and in Hokkaido, Tohoku and Kyushu are identified during the advance, not on the day.

2. China — Tension Level: High

The Japan–China relationship remains in the structural deadlock that began with Prime Minister Takaichi's November 2025 Diet remarks characterising a forcible Chinese move against Taiwan as a potential survival-threatening situation for Japan. Beijing's travel advisory against Japan, its suspension of Japanese seafood imports and its restrictions on dual-use and rare-earth exports to Japan have all remained in force through 2026, and Takaichi has not retracted the remarks. During the reporting week the friction sharpened around diplomacy rather than incidents: on September 21 the foreign ministers of Japan, the United States and South Korea issued a trilateral statement on the margins of the U.N. General Assembly emphasising peace and stability across the Taiwan Strait and opposing unilateral attempts to change the status quo, without naming China. On September 22 Takaichi met President Trump in New York for a 35-minute session focused on China, economic security, semiconductors, AI and critical minerals — deliberately staged two days before Xi Jinping's Washington summit, where Beijing is expected to press for curbs on U.S. arms sales to Taiwan. Chinese coast guard presence in the contiguous zone around the Senkaku Islands continues as a near-daily baseline.

Source: The Japan Times | The Japan Times | The Japan Times

💡Tips for Professionals: Chinese-national principals and China-affiliated facilities in Japan remain in an environment shaped by an active state travel warning citing assaults — increase situational awareness and reduce pattern predictability near the Chinese Embassy (Minami-Azabu 3-chōme, Minato Ward) and the Osaka Consulate-General. Advise principals against public commentary on Taiwan, the Senkakus or wartime history for the duration, and monitor for right-wing sound-truck activity and counter-protest around diplomatic premises in the days surrounding the U.S.–China summit.

3. Russia — Tension Level: Elevated

No new bilateral incident was reported in the September 16–23 window, but the relationship remains at its worst level in decades following President Putin's August 13 visit to Etorofu (Iturup) in the Northern Territories — the first trip to the disputed islands by a Russian president since 2010. Japan lodged a formal protest and summoned the Russian ambassador; Moscow reciprocated by summoning Japan's envoy on August 18. Foreign Minister Motegi has stated that Russia's military build-up on the four islands is unacceptable to Japan. Russia subsequently conducted a rare missile test near the islands in late August. Russian intelligence-gathering aircraft continue to transit the Sea of Okhotsk and the Pacific along Japan's eastern seaboard, prompting routine Air Self-Defense Force scrambles, and Japan continues to sanction Russia alongside the G7 while supporting Ukraine.

💡Tips for Professionals: Northern-Territories anniversaries and Russian official visits reliably generate nationalist sound-truck activity and small demonstrations outside the Russian Embassy (Azabudai, Minato Ward) and around the Diet — factor both into central Tokyo routing. For client operations in eastern Hokkaido, note that maritime and airspace activity near Nemuro and the Shiretoko coast can trigger short-notice port and coastal-road restrictions.

🌋 Section 3: Natural Disaster Report

Typhoon Dujuan (Typhoon No. 25): Record Rainfall, Landslides and Fatalities Across the Kantō Region (September 20–22, 2026)

Typhoon Dujuan, the 25th named storm of the season, tracked into the Izu Islands and the Kantō region on September 21 and passed east into the Pacific by September 22, transitioning to an extratropical low east of Hokkaido by September 23. At 4:00 p.m. on September 21 the system was about 130 km southeast of Katsuura, Chiba Prefecture, moving northeast at 35 kph with central pressure of 960 hPa, maximum sustained winds of 40 m/s and gusts to 55 m/s. The Japan Meteorological Agency issued its highest-level (Level 5) landslide special warning for parts of the Izu Islands including Ōshima, with Level 4 warnings across much of Kantō. Izu Ōshima recorded 832 mm of rain in 48 hours to 1:30 a.m. September 22 — an all-time record for the station and more than double its normal September total — while 325 mm fell in the Rinkai area of Tokyo's Edogawa Ward and 324 mm at Sakahata in Kimitsu, Chiba.

As of September 22, six people were confirmed dead and at least six missing. Fatalities and missing persons were concentrated in landslide-struck homes in Chiba Prefecture (Kamogawa, Sanmu, Mobara, Sodegaura) and Kanagawa Prefecture (Yokosuka, Miura); one earlier death was recorded in Miyazaki Prefecture. Police, fire services and the Self-Defense Forces continued search operations. The Cabinet Office applied the Disaster Relief Act to 25 municipalities. More than 470 buildings were damaged across Kanagawa, Chiba and Ibaraki; tens of thousands of households in Chiba and Kanagawa remained without power. Roads around JR Sakura Station in Chiba stayed flooded to nearly one metre after the Takasaki River overflowed. Japan Airlines cancelled 120 domestic flights and All Nippon Airways 140; JR East suspended services on lines in Chiba, Ibaraki and western Tokyo; and the Tokyo Game Show cancelled its final day. JMA has warned that saturated ground and swollen rivers keep landslide risk elevated even after the storm's departure.

Ongoing: Mount Tokachidake Volcanic Alert Remains at Level 3 — Hokkaido

The Japan Meteorological Agency raised the eruption alert for Mount Tokachidake (2,077 m) in central Hokkaido to Level 3 (do not approach the volcano) on the morning of September 12, 2026, following a sustained increase in volcanic earthquakes since August. This is the first Level 3 designation for the mountain since the current alert framework was introduced in 2008. The restricted zone extends roughly three kilometres from the active crater, and entry to the summit area is banned. The alert remained in force throughout the reporting period. Shirogane Onsen and the surrounding resort areas have remained open, but hiking routes are closed.

Source: The Japan Times

Seismic Activity: No Damaging Earthquakes Recorded

Japan recorded no earthquake producing significant damage during September 16–23, 2026. The largest event in the period was an M5.0 offshore Amami Ōshima on September 20 at 4:28 p.m., registering a maximum seismic intensity of 3 on the JMA scale with no reported damage. Other notable events were an M4.8 in southern Ibaraki Prefecture on September 17 (maximum intensity 3) and an M4.8 in the Hyūga-nada on September 21 (maximum intensity 3). No tsunami advisories were issued.

Source: Japan Meteorological Agency

💡Tips for Professionals:

• Treat Chiba and Kanagawa as active recovery zones through at least early October. Coastal and hillside routes in Yokosuka, Miura, Kamogawa and Sanmu carry ongoing closure, single-lane restriction and emergency-vehicle priority. Do not rely on navigation apps for routing in these areas — verify against prefectural police and municipal road-closure notices before departure.
• Post-typhoon landslide risk persists for days after rainfall stops. If a principal's residence or venue sits below a slope in the affected prefectures, obtain the municipality's hazard-map designation before confirming the stay.
• Haneda and Narita transfers through Chiba remain vulnerable to residual rail disruption. For movements in the coming week, build in a rail-failure contingency with a surface alternative, and confirm flight status the evening before rather than on the morning of departure.
• For client itineraries in central Hokkaido, remove Tokachidake summit and crater-area routes from planning entirely while Level 3 stands, and confirm alert status on the JMA site on the day of any Daisetsuzan-area movement.

📅 Section 4: Upcoming Major Events & Traffic Restrictions

Tokyo

Grand Sumo Autumn Tournament (Aki Basho) — Final Days — through Sunday, September 27, 2026

• Location: Ryōgoku Kokugikan, Sumida Ward
• Traffic: No formal road closures. Heavy pedestrian and taxi congestion around JR Ryōgoku Station and Kokugikan-dōri on the final days (September 26–27); doors open 10:00 on the final day, with large crowd egress from roughly 18:00.

Nezu Shrine Grand Festival / Shinkōsai Mikoshi Procession — Saturday, September 26 – Sunday, September 27, 2026

• Location: Nezu Shrine and surrounding parish, Bunkyō Ward (Nezu / Sendagi / Yanaka area). Main shrine mikoshi procession departs 09:00 and returns 16:00 on September 27 — a procession held only once every four years.
• Traffic: Rolling street closures and heavy pedestrian congestion in the parish area. The Tokyo Metropolitan Bureau of Transportation has warned of major delays on six Toei bus routes (Kami-26, Higashi-43, Cha-51, Kami-58, Kami-60, Kusa-63) from approximately 08:00 to 21:00 on both September 26 and 27.

59th Fukuro Matsuri — Eve Festival and Mikoshi Festival — Saturday, September 26 – Sunday, September 27, 2026

• Location: Ikebukuro West Exit area, Toshima Ward (Ikebukuro Nishiguchi Park and surrounding shopping streets). September 26: eve festival and opening ceremony. September 27: the Mikoshi Festival, in which large numbers of portable shrines and bearers process through the west-exit district.
• Traffic: Street closures around the Ikebukuro west exit precinct, with taxi and bus boarding points relocated from their normal positions for the duration. Organisers have issued a formal prohibition on drone filming over the festival area. The autumn festival and 27th Tokyo Yosakoi follow on October 10–11.
• Source: Fukuro Matsuri Organising Committee | Ikebukuro West Gate Shopping Association

Miyashita Park Bon Odori — Saturday, September 26 – Sunday, September 27, 2026

• Location: Miyashita Park rooftop, Shibuya Ward
• Traffic: No road closures announced, but elevated pedestrian density on Meiji-dōri and around Shibuya Station across both evenings, compounding the station area's existing congestion.
• Source: Time Out Tokyo

Autumn National Traffic Safety Campaign — Monday, September 21 – Wednesday, September 30, 2026

• Location: Nationwide, including all Tokyo wards
• Traffic: Intensified roadside enforcement by the Metropolitan Police Department: seat-belt and child-restraint checks, mobile-phone-while-driving enforcement, drink-driving checkpoints and early-headlight campaigns at dusk. September 30 is designated the day targeting zero traffic fatalities.
• Source: Government of Japan Public Relations Office | Tokyo Metropolitan Police Department

💡Tips for Professionals (Tokyo): The two mikoshi festivals on September 26–27 are the week's principal movement risk in Tokyo — both produce dense, slow-moving crowds in narrow streets with limited vehicle access and unpredictable rolling closures. For any principal movement in Bunkyō or Toshima wards on those dates, plan to stage vehicles outside the parish boundary and complete the last leg on foot with a pre-walked route, rather than attempting vehicle access. Add 30 minutes to all Ikebukuro and Nezu/Sendagi transits. Across the city, enforcement density through September 30 makes a mid-movement traffic stop a realistic disruption: confirm driver documentation, vehicle papers and insurance certificates before each detail, and instruct drivers that hands-free compliance is non-negotiable. Looking slightly beyond this window, the Tokyo Legacy Half Marathon on October 18 will close central metropolitan roads until around midday — begin advance planning now for any client activity that weekend.

Nagoya & Aichi Prefecture

20th Asian Games (Aichi-Nagoya 2026) — Saturday, September 19 – Sunday, October 4, 2026

• Location: 24 venues across Aichi Prefecture and Nagoya City; ceremonies and athletics at Nagoya City Mizuho Park Athletic Stadium (Paloma Mizuho Stadium), Mizuho Ward
• Traffic: Temporary restrictions throughout the prefecture tied to the torch relay, ceremonies and road events. Organisers are formally requesting that private vehicles be avoided. Security screening and identity verification at venues are the stated cause of entry congestion.
• Source: Aichi-Nagoya 2026 Organising Committee | City of Nagoya

Athletics Competition (including road events) — Wednesday, September 23 – Tuesday, September 29, 2026

• Location: Paloma Mizuho Stadium, Mizuho Ward, plus public-road courses in Naka Ward
• Traffic: Half-marathon race walk on September 23 (men's and women's simultaneous start, 07:30) on the public-road loop course around the Aichi Prefectural Government Office and Nagoya City Hall; the marathon race walk follows on September 27 at 07:30 on the same loop. The government district around the Prefectural Office, City Hall and the southern side of Nagoya Castle is the primary restricted zone on both mornings.
• Source: Aichi-Nagoya 2026 Organising Committee

Marathon (Men's and Women's) — Saturday, September 26, 2026

• Location: Start and finish at Paloma Mizuho Stadium; two laps between Mizuho Undōjō-nishi intersection and Meijō Park intersection, running north–south through central Nagoya past Nagoya Castle and the TV Tower
• Traffic: Road closures along the course from approximately 06:45 to 11:20. Men's start 07:30, women's start 07:50. Partial suspensions and delays are expected on public transport serving the corridor.
• Source: Aichi-Nagoya 2026 Organising Committee

Cycling Road Race — through Friday, October 2, 2026

• Location: 23 km circuit through the Tsukude and Hōrai districts of Shinshiro City, eastern Aichi
• Traffic: Extended rural road closures on the circuit; men's race over 161 km, women's over 91 km. Detour routes through mountainous terrain add substantial journey time.
• Source: Aichi-Nagoya 2026 Organising Committee

Closing Ceremony — Sunday, October 4, 2026, 18:00

• Location: Paloma Mizuho Stadium, Mizuho Ward
• Traffic: Ceremony-scale restrictions and a further large-scale police deployment expected around the Mizuho Park perimeter.
• Source: Aichi-Nagoya 2026 Organising Committee

💡Tips for Professionals (Nagoya & Aichi): The marathon on September 26 effectively bisects central Nagoya north–south for the whole morning — any client movement between the city centre and the south/southeast of the city before 11:30 that day must either be completed before 06:30 or deferred. On September 23 and 27 the government district in Naka Ward is closed for race walk, which removes the normal approaches to the Prefectural Office, City Hall and Nagoya Castle area; use subway (Meijō and Sakura-dōri lines) for principal movement rather than attempting vehicle access. For Chubu Centrair (NGO) transfers throughout the Games, use the Meitetsu μ-SKY rather than road, and add a minimum of 45 minutes over normal planning. Expect identity verification at every venue: pre-register accreditation, carry photo ID for all team members, and brief that drones, laser pointers and large bags will be refused.

Osaka

Osaka-jō Hall Arena Concert Series — Wednesday, September 23, Saturday, September 26 and Sunday, September 27, 2026

• Location: Osaka-jō Hall, 3-1 Osakajō, Chūō Ward, Osaka
• Traffic: Three consecutive arena-scale events. September 23: LIVE "Kimi to Aruita Seishun" 2026 (doors 17:00, start 18:00). September 26: EXILE THE SECOND (doors 15:00, start 16:00). September 27: EXILE THE SECOND (doors 14:00, start 15:00). No formal road closures are announced, but severe pedestrian congestion builds around Osakajōkōen and Morinomiya stations and on the Osaka Castle Park approach roads for roughly 90 minutes before doors and 45 minutes after curtain. Vehicle drop-off capacity at the hall is very limited on event days.
• Source: Osaka-jō Hall

💡Tips for Professionals (Osaka): Osaka-jō Hall discharges its audience into a park with few vehicle egress points; a post-show pickup at the main entrance is effectively a 30–45 minute trap. Pre-position vehicles on the Morinomiya side and walk the principal out through the park rather than staging at the hall, or hold and depart 25 minutes after the crowd. Evening starts on all three dates mean egress falls in darkness — confirm lighting and footing on the walking leg during the advance. Kansai is otherwise clear of major restrictions this week: the Kishiwada Danjiri Festival's main rounds concluded on September 19–20, with the second-district rounds falling in October.

Chiba & Kanagawa (Greater Tokyo Recovery Zones)

Typhoon Dujuan Recovery Operations — ongoing through late September 2026

• Location: Yokosuka and Miura (Kanagawa); Kamogawa, Sanmu, Mobara, Sodegaura and Sakura (Chiba)
• Traffic: Landslide-related road closures, single-lane restrictions, standing floodwater around JR Sakura Station, and heavy emergency-services and Self-Defense Forces vehicle movement. The Disaster Relief Act has been applied to 25 municipalities. Power restoration works continue.
• Source: The Japan Times

💡Tips for Professionals (Chiba & Kanagawa): Treat all coastal and hillside routing on the Miura and Bōsō peninsulas as unreliable for at least another week. If a client requires movement into these areas, send an advance vehicle and confirm the route physically; emergency-vehicle priority means a protective convoy can be held indefinitely at a single-lane control point. For Narita-bound movements, verify JR and Keisei line status the evening before and hold an expressway alternative.
