Japan Protective Security Report (Weekly)

Report: August 12 – August 19, 2026

Published: Wednesday, August 19, 2026 (JST)

A weekly English-language OSINT briefing for executive protection professionals, close protection officers, and corporate security managers operating in or travelling to Japan.

🔒 Section 1: Weekly Security News Summary

12-Year-Old British Visitor Missing for 59 Hours in Greater Tokyo, Recovered Unharmed in Yokohama

A 12-year-old British girl travelling in Japan with her family was reported missing from the family's private rental accommodation in Minami-Kamata, Ota Ward, Tokyo, on the morning of August 13. She was located roughly 59 hours later when she presented herself at a police box in Yokohama at approximately 8:00 p.m. on August 15 and was taken into protective custody unharmed. Police released her details publicly during the search and stated afterwards that no criminal involvement was indicated. She had travelled independently to anime-related sites around Yokohama and spent nights in internet cafés.

💡Tips for Professionals:

• Accompanying family members — particularly minors and young adults — are the most common accountability failure in low-threat leisure programmes in Japan. Build a documented headcount protocol into every itinerary that includes dependants, with defined check-in intervals and a named responsible adult per sub-group.
• Japan's low violent-crime baseline encourages families to relax movement discipline; this case shows a minor can travel 30 km across two prefectures and remain unlocated for over two days. Pre-brief all family members on the koban (police box) network as the fastest recovery mechanism, and pre-load koban locations near accommodation and planned venues.
• Internet cafés, manga cafés and capsule facilities are widely used, cash-friendly and frequently outside CCTV-rich environments — treat them as a standing search category in any missing-person plan in Japan.

Record Methamphetamine Seizure in Passenger Baggage at Kansai International Airport

Osaka Prefectural Police and Osaka Customs announced on August 13 the arrest and indictment of a 26-year-old US national over an attempt to import approximately 20–21 kg of methamphetamine, with an estimated street value of about ¥1.1 billion, through Kansai International Airport. The narcotics were concealed in a suitcase and backpack on a flight arriving from Honolulu. Authorities described the quantity as the largest ever detected in passenger carry-on and checked baggage at the airport since it opened, and are treating the case as organised smuggling.

💡Tips for Professionals:

• Expect measurably longer and more intrusive customs processing at KIX for arrivals from Pacific and North American origins in the weeks following a record seizure. Rebuild airport-to-vehicle timelines with an added 30–45 minute buffer for principals arriving on those routings.
• Never allow staff, crew or advance personnel to carry, consolidate or accept baggage on behalf of another party — the routine courier profile in these cases is a foreign national carrying for a third party. Reconfirm this rule in writing before every inbound movement.
• Meet-and-greet and expedited arrival services do not exempt a principal from secondary inspection. Where a principal's schedule is time-critical, plan the first appointment with the assumption that secondary screening will occur.

National Flag Desecration Law Enters into Force, Raising Protest-Policing Friction

Legislation criminalising public damage to, removal of, or defacement of the Japanese national flag took effect on August 13. Passed by the House of Representatives on June 30 and the House of Councillors on July 17, the law provides for up to two years' imprisonment or a fine of up to ¥200,000. Legal scholars and human rights organisations have argued the statute's subjective standard — conduct causing significant offence or hatred in others — creates uncertainty over what is punishable and may chill expression. Enforcement posture at demonstrations is expected to be the first practical test.

Source: The Japan Times

💡Tips for Professionals:

• A new public-order offence changes the arrest threshold at demonstrations, which in turn changes crowd dynamics: anticipate more assertive police lines, more arrest activity, and therefore more sudden crowd compression at political gatherings in Tokyo through the autumn.
• Advance teams should re-baseline standing assumptions about protest sites (National Diet, Kasumigaseki, Chinese and other embassies, Yasukuni vicinity). Routes previously assessed as "static protest, low kinetic risk" may now generate detention incidents and secondary confrontation.
• Brief foreign principals and their staff that flag-related conduct, including symbolic acts intended as harmless, now carries criminal exposure in Japan. This is a real reputational and legal risk for visiting delegations and media-facing personnel.

Nichirei Confirms Employee Data Compromise as Ransomware Wave Continues Against Japanese Firms

Frozen-food and logistics group Nichirei announced on August 14 that employee information may have been exfiltrated in the July system compromise that disrupted its shipping and order operations. Affected data reportedly includes names, dates of birth, corporate email addresses, employee numbers, and HR and labour-management records. The extortion group that claimed the intrusion had published stolen files online on August 10. Multiple other Japanese manufacturers and distributors were listed on extortion sites during the same week, indicating sustained targeting of Japan's industrial and logistics sector.

Source: Nikkei

💡Tips for Professionals:

• HR and labour records are a protective-intelligence problem, not only a privacy problem: home addresses, dates of birth, employee numbers and internal reporting lines are precisely the material needed to build a targeting package against an executive or their staff. Treat any confirmed HR-system breach at a client as a trigger for a residential-security and threat-assessment review.
• Audit whether your own EP vendor records — advance reports, route plans, driver rosters, principal schedules — sit on client-managed infrastructure that could be encrypted or exfiltrated. Maintain an offline copy of current operational plans and emergency contact trees.
• Ransomware in Japan has repeatedly disrupted physical logistics, not just IT. Verify that client facilities have manual override procedures for electronic access control, gates and CCTV, and that guard forces have rehearsed them.

JASDF F-15 Emergency Landing Closes Naha Airport Second Runway for Over Four Hours

An Air Self-Defense Force F-15 from Naha Air Base made an emergency landing at approximately 12:53 p.m. on August 18 and became immobilised on the runway after a landing-gear malfunction. Naha Airport's second runway was closed from 12:57 p.m. and did not reopen until 5:06 p.m. The pilot was uninjured. Around 40 commercial flights were affected, with delays of up to approximately 35 minutes.

Source: Okinawa Times

💡Tips for Professionals:

• Naha is a shared civil–military field; a single military airframe incident removes half the runway capacity with no notice and no published restoration time. Any Okinawa itinerary with a hard downstream commitment needs a stated hold-or-divert decision point, not an assumption of on-time departure.
• Build ferry and inter-island alternatives into Okinawa plans in advance rather than improvising. Peak summer load means rebooked seats disappear within minutes of a disruption announcement.
• The same exposure applies at other joint-use fields used for VIP movement (Komaki, Iruma, Hyakuri). Where a principal's route depends on a joint-use airport, confirm the secondary civil airport and the surface-transfer time before departure.

Attempted-Murder Defendant Absconds from Hakodate Hospital During Suspended Detention

A 77-year-old man indicted for attempted murder — accused of striking his wife on the head with a hammer at their home in June — disappeared from a Hakodate hospital on the evening of August 16, hours after the court granted a suspension of detention so he could receive treatment. The court cancelled the suspension the same day. The Hakodate District Public Prosecutors Office and Hokkaido Police were still searching for him as of August 18.

Source: Hokkaido Shimbun, Jiji Press

💡Tips for Professionals:

• Medical facilities are the standard weak point in custody chains worldwide, and Japan is no exception. Where a client organisation has a known threat actor in the justice system, establish a notification channel with the handling prosecutor's office rather than relying on media reporting to learn about release, bail or detention suspension.
• Japanese authorities do not routinely notify private parties of custody status changes. For stalker, ex-employee and domestic threat cases, victim-notification arrangements must be requested explicitly and re-confirmed periodically.
• Reassess residential security posture for any protected person linked to an offender whose custody status may change — the window between a status change and public reporting is where most incidents occur.

Tokyo Police Re-Arrest Organised Crime Member Over Trafficking of Young Women to Overseas Scam Compounds

The Tokyo Metropolitan Police re-arrested a 26-year-old member of a designated organised crime group on August 17 on suspicion of human trafficking for the purpose of transporting a woman abroad. Investigators allege young people were recruited from the "Toyoko" area near Shinjuku's Kabukicho with promises of extremely high earnings and taken to Southeast Asia, where at least one victim was forced to work as a telephone fraud operator. The case forms part of a wider crackdown on anonymous, fluid criminal networks — the so-called tokuryū groups — that recruit through social media and messaging apps.

Source: Yomiuri Shimbun

💡Tips for Professionals:

• Tokuryū recruitment is the same infrastructure that supplies burglary and robbery crews for high-value residential targets in Japan. A single recruited insider — a domestic staff member, driver or contractor — is the realistic access vector, not forced entry. Vet household and vendor staff, and re-vet on a schedule.
• Kabukicho and the surrounding Shinjuku night-district blocks remain the highest-density recruitment and predation environment in Tokyo. Treat unescorted movement there by junior staff, dependants or young principals as a specific risk to be planned against, not an ordinary night out.
• Brief young family members that unsolicited "high-paying short-term work" offers circulating on Japanese social platforms are a recognised trafficking and criminal-recruitment channel, including for foreign residents.

🌏 Section 2: Japan–Foreign Nations Tension Monitor

1. North Korea – Tension Level: High

North Korea conducted its second ballistic missile test in under a week on August 12, firing from the Wonsan area on the east coast; South Korea's Joint Chiefs of Staff assessed a flight of more than 700 km. Japan's Defence Minister Shinjiro Koizumi said Tokyo lodged a strong protest through the two countries' embassies in Beijing and called the launch a serious problem for public safety. On August 14, Pyongyang warned it would answer the upcoming allied exercise with overwhelming force. The 11-day US–South Korea "Ulchi Freedom Shield" exercise began on August 17 and runs to August 27, incorporating counter-drone, GPS-disruption and cyber-defence components.

Source: Al Jazeera, The Washington Post, UPI

💡Tips for Professionals: The August 17–27 exercise window is the historically reliable trigger period for further launches, and a launch on a Japan-overflight azimuth activates J-ALERT with immediate Shinkansen suspensions on the Tohoku and Hokkaido lines. Confirm every team member has J-ALERT-capable alerting enabled on a Japanese SIM or roaming profile, rehearse a shelter-in-place decision that does not depend on a principal's consent in the moment, and avoid scheduling irreversible rail-dependent movements in northern Japan during this window.

2. China – Tension Level: High

Four China Coast Guard vessels entered Japanese territorial waters off Kuba-jima in the Senkaku Islands on the afternoon of August 14, remaining inside the territorial sea for approximately 90 minutes before withdrawing, according to the 11th Regional Coast Guard Headquarters. Separately, Beijing lodged a strong protest on August 15 after Prime Minister Sanae Takaichi sent a ritual offering to Yasukuni Shrine and Defence Minister Shinjiro Koizumi, Economic Security Minister Kimi Onoda and other Cabinet and LDP figures visited the shrine on the 81st anniversary of Japan's surrender. China's Foreign Ministry characterised the visits as an attempt to obscure wartime responsibility, and its Defence Ministry separately urged vigilance against Japanese remilitarisation. The maritime pattern remains one of near-continuous presence in the contiguous zone punctuated by short territorial-sea entries.

Source: NHK, Nikkei, NHK

💡Tips for Professionals: Yasukuni-linked friction historically produces a two-to-three-week tail of elevated activity around the Chinese Embassy in Minami-Azabu, Minato Ward, the Yasukuni and Kudanshita precinct, and Chinese consulates in Osaka, Fukuoka, Nagoya, Sapporo and Niigata — including both nationalist counter-protest and threats against Chinese diplomatic facilities. For Chinese-national principals, raise counter-surveillance measures and reduce pattern predictability; for Japanese corporate principals with China exposure, re-check travel security arrangements on the mainland side before any inbound trip.

3. South Korea – Tension Level: Moderate

Seoul's Foreign Ministry expressed regret over the August 15 Yasukuni offering and ministerial visits, using its standard formulation rather than escalating to summons or countermeasures. The reaction sits against an unusually constructive bilateral baseline: President Lee Jae-myung and Prime Minister Takaichi have met repeatedly over the preceding months, including reciprocal hometown summits in Nara and Andong, and both governments have continued to institutionalise security and energy cooperation. Historical-memory friction therefore remains rhetorically live but has not disrupted the working relationship, and it is being managed alongside a shared focus on North Korean missile activity.

Source: NHK

💡Tips for Professionals: Threat levels against South Korean nationals and facilities in Japan remain at baseline; no elevated posture is warranted this week. Maintain normal situational awareness only in symbolically charged precincts (Kudanshita, the Diet area) around commemorative dates, and note that the strength of the current bilateral relationship makes trilateral Japan–US–ROK military activity a more likely driver of North Korean rhetoric than of Japan–ROK friction.

4. Russia – Tension Level: Moderate

No new Japan–Russia incident was reported during the August 12–19 window. The most recent significant event remains the July 25 violation of Japanese airspace by a Russian military aircraft over islets claimed by Tokyo in the Northern Territories, which drew a formal protest. Japan continues to describe the occupation of the Northern Territories as illegal in its diplomatic documentation, and Russia–North Korea military cooperation remains a stated Japanese security concern. Air Self-Defense Force scramble activity in the northern approaches continues at an elevated routine level.

Source: The Japan Times

💡Tips for Professionals: Northern Hokkaido and the Nemuro/Rebun–Rishiri maritime corridors remain the sensitive zone; airspace incidents there can produce short-notice regional airspace restrictions and Chitose-routed flight delays. For principals travelling in Hokkaido, keep a surface-transport fallback for any northern leg and avoid committing to same-day connections out of New Chitose.

5. United States – Tension Level: Low

Alliance relations remain stable, with no bilateral friction incident reported in Japan during the reporting week. The principal development affecting the regional posture is President Trump's August 17 statement that the United States will substantially reduce the scale of its joint military exercises with South Korea, announced while Ulchi Freedom Shield was already under way. Any structural reduction in allied exercise tempo has second-order implications for Japan's deterrence calculus and for the operating rhythm of US facilities in Japan, though no changes to US installations in Japan were announced this week.

Source: Al Jazeera

💡Tips for Professionals: No elevated posture is required for US-affiliated principals or facilities. Standard protocols remain appropriate around the Embassy in Akasaka, Yokosuka, Atsugi, Yokota, Iwakuni and the Okinawa installations; note only that Okinawa base-access and flight-line activity is currently more disruptable than usual following the August 18 Naha runway event.

🌋 Section 3: Natural Disaster Report

1. "Reiwa 8 August Chiba Heavy Rain" — Record Rainfall and Catastrophic Flooding (August 13–14)

Successive linear precipitation bands stalled over Chiba Prefecture on August 13–14, producing 367.0 mm of total rainfall and 115.0 mm in a single hour at Chiba City — both local records. The Japan Meteorological Agency issued Level 5 emergency heavy-rain warnings for 22 municipalities and Level 5 landslide warnings for six, and formally named the event on August 14 — its first such naming in six years. As of August 17–18, 13 people were confirmed dead, two missing and 34 injured, with more than 2,300 buildings flooded, over 24,000 households losing power, and around 7,000 passengers stranded at Narita Airport. One fatality resulted from carbon monoxide poisoning caused by indoor generator use during the blackout. Twenty-five cities and towns have been designated under the Disaster Relief Act.

2. Chiba Recovery Status — Rail and Road Restrictions Persist Into the Coming Week (Ongoing)

Recovery is incomplete and will constrain movement in eastern Chiba through late August. JR East's Sotobo Line resumed the Oami–Honno section on August 18, but the Honda–Oami section — where ballast was washed out at Toke Station and in an adjacent tunnel — is not expected to reopen until August 24, with replacement buses running between Honda–Toke and Soga–Mobara from 6:00 a.m. to 9:00 p.m. More than 1,300 vehicles were abandoned on flooded roads across the prefecture; the Chiba National Highway Office has been clearing them from National Routes 6, 14, 16, 51 and 357 to restore emergency-vehicle access. Expressway closures have been lifted, but water outages continued in parts of the prefecture.

3. Typhoon Season — Chan-hom Exits After Unprecedented Ibaraki Landfall; Two Systems Stay Offshore (August 11–16)

Typhoon No. 15 (Chan-hom) made landfall near Kashima City in southern Ibaraki Prefecture at around 8:00 p.m. on August 11 with a central pressure of 980 hPa — the first typhoon landfall in Ibaraki Prefecture since records began in 1951, and the product of an unusual east-to-west approach track. It crossed Honshu overnight, passed Fukui Prefecture by 6:00 a.m. on August 12 and weakened to a tropical depression over the Sea of Japan at 9:00 a.m. Typhoon No. 16 (Peilou, August 8–13) and Typhoon No. 17 (Nangka, August 11–16) both tracked well offshore with no direct impact on Japan. The 2026 season is running ahead of the seasonal average for named storms.

4. Seismic Activity — No Intensity-5 Events in Japan; Kumamoto Aftershock Sequence Continues

No earthquake registering JMA seismic intensity 5-lower or above occurred anywhere in Japan during the August 12–19 window. The two largest events affecting Japanese territory were a magnitude 5.4 near Iwo Jima on August 16 (maximum intensity 1) and a magnitude 5.1 west of the Ogasawara Islands on August 14 (maximum intensity 1), neither with damage or tsunami risk. The aftershock sequence from the magnitude 7.1 "Reiwa 8 Kumamoto Earthquake" of July 28 — which produced maximum intensity 7 at Uki City and Hikawa Town — continues in gradual decline but remains active. The JMA advises that earthquakes of around intensity 5-lower or greater remain possible in the affected area for one to two months from the mainshock, a window running into late September.

Source: Japan Meteorological Agency

5. Extreme Heat — Record Number of Extremely Hot Days Nationwide

Japan's 2026 summer has produced a sharp escalation in heat since mid-July, with the number of locations recording 40°C or above reaching record levels and July logging the second-highest count of extremely hot days on record. Kumamoto City and Kikuchi City recorded their first-ever 40°C-class days on August 3, and the Tokai region recorded five consecutive such days. Forecasters expect above-normal temperatures to persist into late August, particularly in western Japan, with continued severe heatstroke risk. Heat is compounding disaster response in Chiba, where power and water outages have coincided with peak temperatures.

💡Tips for Professionals:

• Chiba and Narita routing is the operational headline. Narita access should be planned on the assumption of degraded rail redundancy through August 24: if the Sotobo Line or a Chiba surface route forms part of a contingency plan, that contingency is currently unavailable. Use Narita Express plus a pre-positioned vehicle, and treat the Keisei Skyliner as the primary rail alternative rather than any JR line routed through eastern Chiba.
• Post-flood road hazards outlast the water. More than 1,300 abandoned vehicles, scoured shoulders, undermined pavement and displaced manhole covers persist for weeks after floodwater recedes. Advance any Chiba ground route physically before running a principal over it; do not rely on navigation apps, which do not reflect washouts or informal closures.
• Generator carbon monoxide killed someone in this event. If a client residence or safe house has a portable generator, confirm in writing that it is sited outdoors and that staff have been briefed. This is the single most preventable death mode in Japanese blackout scenarios.
• Heat is currently a higher-probability medical threat to a protection detail than any hostile act. Rotate outer-perimeter and static personnel on a fixed schedule rather than by feel, mandate electrolyte intake, and pre-identify the nearest emergency department for every venue. Suited close-protection officers working exterior positions in Kanto and western Japan are in the highest-risk category.
• Kumamoto remains in an active aftershock window into late September. For any Kyushu movement, confirm accommodation seismic standards, identify evacuation routes on arrival, and expect intermittent Kyushu Shinkansen and expressway inspection stoppages after any felt event.

📅 Section 4: Upcoming Major Events & Traffic Restrictions

Coverage: August 19–26, 2026

Tokyo

60th Azabu-Juban Noryo Matsuri (Summer Festival) — August 22–23, 2026 (Saturday–Sunday)

• Location: Azabu-Juban shopping district, Minato Ward — Azabu-Juban Station (Tokyo Metro Namboku Line / Toei Oedo Line), Patio Juban and surrounding streets
• Traffic: The festival area becomes a pedestrian-only zone, with vehicle access closed through the shopping district on both days from approximately 2:00 p.m. to 9:30 p.m. No general public parking is provided. Attendance approaches 400,000 across the two days.
• Source: Azabu-Juban Shopping Street Association

Shinagawa Cruise (August Cruises) — August 21–22, 2026

• Location: Shinagawa waterfront, Minato Ward
• Traffic: No road closures announced; localised pedestrian and pick-up congestion at waterfront access points during boarding and disembarkation windows.
• Source: GO TOKYO (Tokyo Metropolitan Government)

💡Tips for Professionals: Azabu-Juban is the single most consequential item on this week's Tokyo calendar for protection work, because the closure area sits inside Minato Ward's embassy and executive-residential belt — the same streets used for routine diplomatic and corporate movement. Re-route principals via Roppongi-dori or Meiji-dori and avoid the Azabu-Juban/Ichinohashi block entirely from 1:00 p.m. on both days; a vehicle that enters the zone before closure may not be extractable until after 9:30 p.m. Where a residence or office lies inside the perimeter, complete all vehicle movements before noon and plan an on-foot walk-out route to a pickup point outside the cordon. Otherwise, Tokyo is in a genuinely quiet week between the Obon peak and the late-August festival cluster — use it for route surveys and advance work.

Osaka / Hyogo (Kansai)

108th National High School Baseball Championship — Final — August 22, 2026 (Saturday)

• Location: Hanshin Koshien Stadium, Nishinomiya City, Hyogo Prefecture (Hanshin Main Line, Koshien Station)
• Traffic: Capacity crowd at a 47,000-seat venue with limited road access and no meaningful spectator parking. Severe congestion on the Hanshin Main Line and on National Route 43 and the Hanshin Expressway Route 3 Kobe Line corridor before and after the match. Egress congestion is concentrated in the 60–90 minutes following the final out.
• Source: Hanshin Koshien Stadium

Osaka Station "Super Summer Festival" Events — August 22–23, 2026

• Location: Toki no Hiroba (5F), Osaka Station City, Kita Ward, Osaka
• Traffic: Indoor concourse event; no road closures. Expect elevated pedestrian density inside Osaka/Umeda Station during afternoon hours (approximately 11:00–17:30).
• Source: West Japan Railway Company

💡Tips for Professionals: The Koshien final is a fixed, well-policed event, but the Route 43 / Hanshin Expressway Kobe Line corridor is the primary Osaka–Kobe arterial and it degrades badly on final day — if a principal is moving between Osaka and Kobe on August 22, either complete the movement before 11:00 a.m. or route inland via the Chugoku Expressway. Do not plan an airport run to Itami or KIX through Nishinomiya in the two hours after the match. Umeda's underground network is the fastest way to move a principal through central Osaka on the 22nd–23rd, but it is also the hardest environment in which to maintain formation; brief the detail on link-up points before entering.

Chiba

Post-Disaster Restoration Works (Ongoing) — through August 24, 2026 and beyond

• Location: Eastern and central Chiba Prefecture — Chiba City, Mobara, Oamishirasato, Ichihara and surrounding municipalities
• Traffic: JR Sotobo Line Honda–Oami section remains suspended until approximately August 24, with replacement buses on the Honda–Toke and Soga–Mobara sections between 6:00 a.m. and 9:00 p.m. Abandoned-vehicle removal continues on National Routes 6, 14, 16, 51 and 357. Expressway closures have been lifted; localised water outages persist.
• Source: Tokyo Shimbun, Ministry of Land, Infrastructure, Transport and Tourism

💡Tips for Professionals: Treat Chiba as a degraded-infrastructure environment for the whole reporting week, not a recovered one. Any Narita-bound movement that would ordinarily use a Chiba surface route as a fallback should substitute a second pre-surveyed road option north of the flood zone. Confirm hotel and venue water supply directly before committing a principal to an overnight stay in the affected municipalities — outage information has been changing daily and is not reliably reflected on booking platforms.

Kyoto

Summer Evening Programme — Ghost-Story Sessions and Yokai Events — August 22–23, 2026, 18:00–21:00 (last entry 20:30)

• Location: Central Kyoto venue programming; multiple sites across the city
• Traffic: No road closures announced. Standard late-summer tourist density on the Kawaramachi and Gion approaches during evening hours.
• Source: Kyoto City Official Travel Guide

💡Tips for Professionals: Kyoto's constraint this week is heat and tourist volume rather than any event closure. Schedule outdoor site visits before 10:00 a.m., and remember that Kyoto's grid offers few genuine alternate routes once Shijo-dori or Kawaramachi-dori congests — a single stalled vehicle can hold a motorcade for 20 minutes with no bypass.

Fukuoka

Local Summer Festivals and Fireworks — August 22, 2026 (Saturday)

• Location: Kurume Castle ruins, Kurume City (evening event, approximately 19:00–20:00); Koishiwara River near Amagi Bridge, Asakura City (fireworks from approximately 19:40)
• Traffic: Localised evening congestion and temporary restrictions on approach roads in Kurume and Asakura. No impact expected on central Fukuoka City or Fukuoka Airport access.
• Source: Crossroad Fukuoka (Fukuoka Prefecture Official Tourism)

💡Tips for Professionals: Central Fukuoka is unaffected this week; the events are outside the city. Fukuoka Airport's short runway-to-city transfer remains the fastest in Japan, but its single runway offers no redundancy — build in a diversion assumption for Kitakyushu or Saga if weather deteriorates.

Look-Ahead: Late August Surge (August 27 – 30)

The week following this reporting period carries a heavy nationwide event load that requires planning now:

• Tokyo Koenji Awa Odori (67th) — August 29–30, Koenji, Suginami Ward. Vehicle entry prohibited 4:10 p.m.–8:30 p.m. both days across the area bounded by Ome Kaido, Kanjo Nana (Ring Road 7), Waseda-dori and Mabashi-dori. No public parking. Source
• 28th Nippon Domannaka Matsuri (Domatsuri) — August 28–30, 16 venues across central Nagoya including Hisaya-odori Park, Oasis 21 and Nagoya Castle, with traffic restrictions around venues. Source
• Hokkaido Marathon 2026 — August 30, start and finish at Odori Park West 4, Sapporo. Traffic restrictions across the central Sapporo course from 5:30 a.m. to 3:30 p.m. Source

💡Tips for Professionals: If a principal has Sapporo, Nagoya or western Tokyo commitments on August 28–30, lock vehicles, drivers and hotel loading-dock access this week — all three cities absorb their full annual peak simultaneously, and late bookings will not be available. The Hokkaido Marathon closure in particular isolates central Sapporo hotels from New Chitose Airport for most of the morning of August 30.
