Japan Protective Security Report (Weekly)

Week of April 22 – April 29, 2026

Published: Wednesday, April 29, 2026 (JST)

🔒 Section 1: Weekly Security News Summary

Bears Emerging from Hibernation Invade Urban Areas Across Tohoku Ahead of Golden Week — Authorities Issue Warnings

Japanese authorities issued warnings across northeastern Japan (Tohoku region) from April 24–27, 2026, as Asiatic black bears emerged from hibernation and were reported near apartment buildings, warehouses, and railway stations at rates exceeding those of 2025 — itself a record year for bear encounters. One possible fatal mauling of a woman was reported in Iwate Prefecture, and a police officer sustained injuries in a separate bear encounter. Aomori Prefecture issued a special warning after five bear sightings in ten days, while Iwate and Fukushima prefectures issued similar alerts. The Guardian reported 238 bear attacks in the twelve months from April 2025, including 13 deaths, the majority occurring in the Tohoku region. Authorities are urging particular caution for Golden Week holidaymakers planning countryside excursions in the northeast.

Sources:

💡Tips:

  • If routing principals through rural Tohoku during Golden Week, avoid early-morning and dusk travel on forest roads or near river valleys — peak bear activity times. Carry noise-making devices and verify accommodation is in bear-exclusion zones.
  • Inform principals planning outdoor activities (hiking, camping, cycling) in Aomori, Iwate, Akita, and Fukushima prefectures that official bear alert levels are elevated; recommend postponing non-essential rural excursions until mid-May.

Japan Lower House Passes National Intelligence Bureau Bill: Major Intelligence Overhaul Moves Forward

Japan's House of Representatives passed landmark legislation on April 23, 2026 to establish a National Intelligence Council chaired by the Prime Minister, and a subordinate National Intelligence Bureau (NIB) to centralise and coordinate intelligence activities across all government ministries. The bill received majority support from the ruling LDP-Innovation Party coalition and several opposition parties; the Communist Party and Reiwa Shinsengumi voted against it. The legislation now moves to the Upper House, where passage is expected by July 2026. The bill mandates that personal privacy be protected and political neutrality maintained, though critics have raised surveillance concerns. This represents Japan's most significant intelligence reform in decades, consolidating functions currently dispersed across the Cabinet Intelligence and Research Office (CIRO), National Police Agency, Ministry of Defense, and other agencies.

Sources:

💡Tips:

  • The NIB's establishment will likely lead to enhanced monitoring of foreign-national activities and expanded information sharing with allied intelligence agencies. Corporate security managers handling sensitive foreign clients in Japan should begin reviewing their operational security protocols in anticipation of a more integrated domestic intelligence posture.
  • Anti-surveillance protest activity is anticipated as the bill progresses through the Upper House — particularly in central Tokyo near the National Diet Building (Nagatacho/Kokkai-gijidomae area). EP teams should monitor for permitted and spontaneous demonstrations in this district through July 2026.

Yasukuni Shrine Spring Festival: South Korean Arrested; China and South Korea Issue Diplomatic Protests Over PM Takaichi's Offering

On April 22, 2026, Tokyo Metropolitan Police arrested a 64-year-old South Korean national at Yasukuni Shrine during its annual spring festival for allegedly obstructing the ceremony. The suspect had displayed a banner urging "war criminals to stop praying" and making territorial claims over the Dokdo/Takeshima islands. On the same day, Prime Minister Sanae Takaichi sent a masakaki ritual offering to the shrine for the second consecutive time as Prime Minister — opting not to visit in person — triggering formal diplomatic protests from both China and South Korea. Over 100 conservative legislators, including a Cabinet minister, prayed at the shrine in person. China's Foreign Ministry condemned the move as "a blatant provocation against international justice," while South Korea expressed "deep regret" and summoned the Japanese ambassador.

Sources:

💡Tips:

  • The Kudanshita/Yasukuni Shrine area (Chiyoda Ward) may see continued small-scale protest activity in the days following the festival. EP teams operating in this district should conduct route surveys and identify clear ingress/egress options not reliant on Yasukuni-dori during heightened tension periods.
  • Diplomatically sensitive dates on the Japanese calendar (spring and autumn Yasukuni festival seasons, August 15 war anniversary) consistently attract nationalist and counter-protest gatherings. Incorporate these recurring dates into your annual advance planning calendar.

'Analog Fraud' Scheme Using Fake Postal Arrest Warrants Targets Elderly Residents in Central Japan

NHK World reported on April 22, 2026 that police in central Japan have confirmed at least 45 cases of a sophisticated "analog fraud" scheme in which fake arrest warrants are delivered via standard postal "letter pack" envelopes — deliberately targeting elderly individuals who are unfamiliar with smartphones and may be less attuned to digital scam warnings. As of the report date, 34 confirmed cases were recorded in Aichi Prefecture, 10 in Gifu, and 1 in Mie. In one documented case in Nagoya, a 78-year-old woman was deceived into placing 26 million yen (approximately USD 163,000) in a paper bag at her home after receiving a phone call from an individual posing as a police officer, followed by delivery of a forged warrant. Police noted the forged documents contained non-standard Chinese characters and incorrect postal codes. The scheme deliberately avoids digital channels to evade cybercrime detection systems.

Sources:

💡Tips:

  • Elderly high-net-worth principals and family members in the Nagoya, Aichi, and Gifu areas are at elevated risk from this scheme. Brief household staff and family members: legitimate police and judicial authorities in Japan do not send arrest warrants by postal letter pack, and do not instruct individuals to leave cash at their homes.
  • For principals who receive unsolicited phone calls claiming to be from police, prosecutors, or courts — advise them to hang up immediately and call the police directly via the national non-emergency line (110) to verify. Ensure that trusted family or security staff contact information is prominently posted near home landlines.

Yokohama Home Invasion Robbery: Two Ex-Convicts Arrested, Linked to Up to Ten Similar Incidents

Kanagawa Prefectural Police arrested Ken Murakami (45) and Yukio Kaji (41) on April 22, 2026, on suspicion of robbery causing injury following a violent home invasion at a Yokohama woman's apartment on April 1. Both suspects are recently released ex-convicts with no fixed address, and both admitted to the allegations. Investigators are examining their potential involvement in nearly ten other similar incidents across Kanagawa Prefecture, some of which reportedly involved sexual assault. The pattern of itinerant, career-criminal perpetrators targeting residential properties — particularly those of women living alone — underscores persistent vulnerability of residential premises in the greater Tokyo/Yokohama metropolitan area.

Sources:

💡Tips:

  • Residential security reviews are recommended for principals and their family members residing in the Kanagawa Prefecture area — particularly those living alone. Ensure that entry door security meets minimum standards: reinforced frame, deadbolt, wide-angle peephole, and chain lock. Do not open doors to unannounced callers.
  • This case reflects a broader trend of organised home invasion targeting by small groups of career criminals operating across prefectural boundaries. Corporate security managers should share this threat profile with household management staff and consider periodic security sweeps of principal residences.

🌏 Section 2: Japan–Foreign Nations Tension Monitor

North Korea — Tension Level: High

North Korea conducted its second cluster-munitions ballistic missile test of April 2026 on April 24, launching five "Hwasongpo-11-Ra" short-range ballistic missiles (SRBMs) armed with cluster bomb and fragmentation mine warheads toward a sea target approximately 136 kilometres away, striking a 31-acre area. Kim Jong Un personally oversaw the test, and Pyongyang released imagery of the cluster munition effects — the first such images made public. Japan's Ministry of Defense confirmed the launches and determined the missiles did not enter Japanese territory or its exclusive economic zone. This marked the seventh SRBM launch of 2026 and the fourth in April alone. South Korean, Japanese, and U.S. intelligence services are jointly analysing the missiles' technical specifications. An earlier cluster munitions test was conducted on April 8.

Why it matters in Japan: North Korea's accelerating cluster-munitions SRBM tests — four launches in April alone — represent a significant escalation in tactical strike capability targeting area concentrations such as military bases, ports, and urban infrastructure. Japan's J-ALERT system activates nationwide for each confirmed launch. EP teams and corporate security managers should maintain pre-planned shelter-in-place procedures and verify that all team members have J-ALERT, NHK World, and wireless emergency alert apps active and enabled on all devices. Coastal areas of Honshu and Kyushu face an indirect psychological threat environment during high-tempo launch periods.

China — Tension Level: High

Sino-Japanese tensions intensified on multiple fronts this week. China's Foreign Ministry formally condemned PM Takaichi's April 22 Yasukuni Shrine offering, calling it "a blatant provocation against international justice and an affront to human conscience." Separately, the Chinese Embassy in Tokyo publicly accused Japanese authorities of failing to act on multiple threats against Chinese nationals and diplomats in Japan — including at least three terrorist threats received since March 2026. Beijing has also expressed strong opposition to Japan's April 21 decision to ease lethal arms export rules and the April 27 launch of a security policy review panel under PM Takaichi examining Japan's "comprehensive national strength," which explicitly references China's defense budget expansion as a driver of the review.

Why it matters in Japan: The combination of Embassy-level threat incidents, unresolved Yasukuni diplomatic friction, and Japan's accelerating defense posture shift creates an elevated threat environment for Chinese-affiliated facilities and personnel in Japan. EP operators protecting Chinese-national clients or conducting operations near Chinese diplomatic facilities (Chinese Embassy: Minami-Azabu 3-chome, Minato Ward) should increase situational awareness and reduce predictability of movement patterns. Heightened counter-protest activity is possible near Yasukuni Shrine (Kudanshita, Chiyoda Ward). Advise principals to maintain a low profile regarding geopolitically sensitive locations and public statements during this period.

Sources:

South Korea — Tension Level: Medium

Japan-South Korea relations faced renewed strain this week over the Yasukuni issue. South Korea expressed formal diplomatic regret on April 22 over PM Takaichi's Yasukuni ritual offering, and the April 22 arrest of a South Korean national at the shrine's spring festival — the man had displayed a banner with anti-Yasukuni messages and territorial claims over the Dokdo/Takeshima islands — drew significant media coverage in both countries. Seoul demanded an apology from Tokyo regarding the Yasukuni offering, which was not forthcoming. The incident did not escalate to full ambassador-level summoning but reflects persistent historical friction that has a proven record of mobilising nationalist sentiment and organised demonstration activity in both countries.

Why it matters in Japan: Yasukuni-related friction between Japan and South Korea periodically generates protests near the shrine (Kudanshita, Chiyoda Ward) and at Japanese and South Korean government facilities. During peak tension periods, EP teams operating in central Tokyo should anticipate small-scale but passionate demonstrations near Yasukuni Shrine, the National Diet Building (Nagatacho), and the South Korean Embassy (Minami-Azabu, Minato Ward). South Korean-national clients in Tokyo may face heightened social friction in historically charged contexts. Monitor for spontaneous gatherings particularly on historically significant dates.

Sources:

United States — Tension Level: Low-Medium

Japan's security relationship with the United States entered a period of structural recalibration this week. Al Jazeera reported on April 24 that Japan's record $58 billion defense budget for FY2026 reflects growing concern that U.S. extended deterrence is weakening, prompting Tokyo to accelerate its "southern shield" build-up in the Nansei/Ryukyu Islands chain to independently deter Chinese military action near Taiwan and in the East China Sea. PM Takaichi on April 27 inaugurated an expert panel to revise Japan's three national security documents by end-2026, with nuclear submarine acquisition and AI-integrated defense systems among the topics under active consideration. Japan also approved expanded lethal arms exports to 17 allied nations on April 21, partially reducing supply-chain dependence on U.S. equipment. No formal bilateral diplomatic friction was reported this week, but the structural shift toward Japanese strategic autonomy is accelerating in both pace and scope.

Why it matters in Japan: Japan's pivot toward greater strategic self-reliance may gradually alter the operational landscape for U.S.-affiliated facilities and personnel in Japan over the medium term. In the near term, the alliance remains robust and U.S. facilities face no elevated direct threat. However, EP operators protecting U.S. government or military clients should be aware of organised domestic opposition sentiment: a Shinjuku rally of over 10,000 protesters in March 2026 opposed PM Takaichi's defense expansion policies. Monitor for permit applications and announced demonstration events near U.S. military facilities (Yokosuka, Okinawa, Camp Zama) and the U.S. Embassy (Akasaka 1-chome, Minato Ward, Tokyo).

🌋 Section 3: Natural Disaster Report

Wildfires: Major Blazes in Otsuchi Town — Iwate Prefecture, Tohoku (April 22–28, 2026)

Two wildfires broke out on April 22, 2026 in mountainous areas of Otsuchi Town, Kamihei District, Iwate Prefecture, and spread rapidly due to dry, windy conditions with no rainfall recorded for five consecutive days. By April 26, the burned area had reached 1,373 hectares and evacuation orders covered 1,558 households — approximately 3,257 residents, or roughly one-third of Otsuchi's total population. At peak, 1,400 firefighters and Japan Self-Defense Force personnel, supported by dozens of helicopters, were deployed. Additional fires broke out in Niigata Prefecture (Nagaoka, Uonuma) and Fukushima on April 26. The Otsuchi fires were formally designated a major disaster on April 28. As of April 28, light rain had reduced the blazes to "largely under control" status after burning a total of approximately 1,618 hectares — making this the second-largest wildfire in Japan since the Heisei era. The cause remains under investigation. One minor injury was reported at an evacuation centre; no fire-related fatalities were confirmed.

Operational Impact: Otsuchi Town and surrounding areas of Kamihei District, Iwate Prefecture, should be treated as active disaster zones with ongoing road closures, high volumes of evacuee and emergency vehicle traffic, and SDF vehicle movements on local roads. All non-essential travel to the Otsuchi/Kamihei district should be avoided or postponed through at least early May 2026. Smoke from the fire zones may affect air quality within 30+ kilometres; principals with respiratory conditions require particular attention during any Tohoku travel. For Golden Week itineraries involving the Tohoku region, verify all route accessibility directly with local authorities before departure — do not rely solely on navigation apps, which may not reflect current closures.

Earthquake: M7.7 Sanriku Earthquake and 7-Day Megaquake Special Advisory — Northeast Japan (Advisory Lifted April 27, 2026)

A magnitude 7.7 earthquake (JMA scale: M7.5) struck off the Sanriku Coast of Honshu at 4:52 p.m. JST on April 20, 2026. JMA subsequently issued a rare "special advisory" for 182 municipalities stretching from Hokkaido to Chiba Prefecture, warning of an elevated probability of a follow-on megaquake (M8.0 or greater) within a 7-day window. An 80-centimetre tsunami was observed at Kuji Port, Iwate Prefecture, and tsunami advisories were issued for the northeastern Pacific coastline. The special advisory was formally lifted on April 27 at 5:00 p.m. JST after the 7-day window elapsed without a major follow-on event. A M6.2 aftershock struck southern Hokkaido's Tokachi region at 5:23 a.m. on April 27, reaching upper-5 seismic intensity on Japan's scale; no casualties or significant damage were reported. Background seismicity off Fukushima and Miyagi continued throughout the reporting week.

Operational Impact: Although the formal megaquake special advisory was lifted on April 27, JMA and seismological experts continue to advise elevated caution in northeastern coastal prefectures, as aftershock sequences following an M7.7 mainshock can persist for weeks to months. EP and corporate security teams with operations in Hokkaido, Tohoku, and Kanto should maintain updated emergency evacuation plans to high ground for all coastal venues, hotels, and event sites. Properties in designated tsunami-inundation zones should be avoided where operationally feasible. Ensure all team members have the NHK World and J-ALERT apps installed and configured to receive emergency alerts in English. The Nankai Trough megaquake scenario (M8–9, affecting Tokai, Kinki, Shikoku, and Kyushu) remains a separate, ongoing long-term risk and is unaffected by this event.

📅 Section 4: Upcoming Major Events & Traffic Restrictions

Tokyo

Golden Week 2026 — National Holiday Period — April 29 (Showa Day) through May 6, 2026 (Constitution Day substitute holiday)

  • Area: Nationwide; Tokyo hotspots include Shibuya, Harajuku, Shinjuku, Asakusa, Ueno, Odaiba, Komazawa Olympic Park, and Yomiuri Land
  • Expected impact: Japan's largest annual travel period — an 8-day stretch encompassing four national holidays. Approximately 160 MPD investigators and Tokyo Metropolitan Government staff are deployed ahead of Golden Week for security and crowd management. Peak crowd days in Tokyo are expected May 3–5. Major tourist areas will be at maximum congestion. Intercity Shinkansen seats are heavily booked; airports at capacity on April 29 and May 2 (JAL/ANA southbound peaks). Highway traffic: outbound peak May 2 (up to 45 km jams forecast by NEXCO East on Tomei/Chuo expressways), inbound peak May 5.
  • Source: NEXCO East | Go Tokyo (TMG) | NHK World-Japan
  • Operational note: Advance route planning is critical throughout Golden Week. Expect 20–45 minute delays at all major Tokyo rail hubs (Shinjuku, Shibuya, Tokyo Station, Ueno) on peak days (May 3–5). For principal movement within Tokyo, plan via subway rather than expressway. For expressway travel, NEXCO recommends departing before 07:00 on May 2 (outbound) and before 06:00 on May 5 (inbound) to avoid worst congestion. Emergency contact protocols should account for mobile network congestion on national holiday peak days.

Metropolitan Expressway ETC-Only Operation During Golden Week — May 3 (from 22:00) and May 6 (from 01:00), 2026

  • Area: Metropolitan Expressway (Shuto Expressway) — all toll gates
  • Expected impact: The Shuto Expressway will operate ETC-only tolling during the specified windows on May 3 and May 6. Vehicles without functioning ETC transponders — including many rental cars and foreign-registered vehicles — will be unable to access the Metropolitan Expressway during these periods.
  • Source: Shuto Expressway (Metropolitan Expressway)
  • Operational note: Security teams operating vehicles on Golden Week must confirm that ETC transponders are installed, registered, and funded in all EP vehicles, advance cars, and support vehicles. Brief all drivers. For any vehicle without ETC, pre-plan complete surface-road alternatives (National Route 246, Route 4, Route 1, etc.) well in advance of May 3 and May 6.

Meat Festival 2026 TOKYO — April 29 – May 10, 2026

  • Area: Odaiba Special Venue, 1-1-16 Aomi, Koto City, Tokyo (Odaiba waterfront)
  • Expected impact: Large outdoor food festival at the Odaiba waterfront throughout Golden Week. High foot traffic expected. Access via Rinkai Line (Tokyo Teleport Station) or Yurikamome (Aomi/Tokyo Big Sight stations). Vehicle access to Odaiba will be congested; avoid Rainbow Bridge during peak afternoon hours (12:00–18:00).
  • Source: Matcha Japan
  • Operational note: Odaiba is a peninsula accessible via limited road and rail routes. Pre-identify both Rainbow Bridge (vehicle) and Yurikamome (rail) exit routes before any principal movement to this venue. Large open-air festival settings present elevated crowd-crush and petty crime risk during peak hours. Advise principals to arrive before noon or after 17:00 to minimise congestion exposure.

Craft Gyoza Festival TOKYO 2026 — April 29 – May 6, 2026

  • Area: Komazawa Olympic Park Central Plaza, Setagaya Ward, Tokyo
  • Expected impact: Open-air food festival at Komazawa Olympic Park. Moderate to high foot traffic. Accessible via Tokyu Den-en-toshi Line (Komazawa-daigaku Station, approximately 15 minutes walk). Limited parking — vehicle approach is not recommended.
  • Source: Matcha Japan
  • Operational note: Komazawa Olympic Park is a large, open facility with multiple exits — a more manageable crowd profile than dense urban festival venues. No formal road restrictions have been announced, but local residential streets around the park will see significantly elevated pedestrian traffic throughout the Golden Week period.

Metropolitan Expressway Route 1 Haneda Line — 48-Hour Full Closure — May 9 (Saturday) 00:00 – May 10 (Sunday) 24:00, 2026

  • Area: Metropolitan Expressway Route 1 Haneda Line (southbound), Higashi-Shinagawa Pier to Samezu Reclamation section
  • Expected impact: Full 48-hour closure of the southbound Haneda expressway link affects all vehicle traffic between central Tokyo and Haneda Airport via Route 1. Alternative routes via National Route 15 (Daini-Keihin) or Expressway C2/B will be significantly more congested. Airport transfer times from central Tokyo should be extended by a minimum of 30–60 minutes during this closure.
  • Source: Tokyo Haneda Airport | Traicy EN
  • Operational note: Although this closure falls slightly outside the core Golden Week window, it directly follows the return-traffic surge (inbound peak May 5–6). Any principal movement to or from Haneda Airport on May 9–10 must use alternative surface routes or rail (Keikyu Line or Tokyo Monorail). Build a 45–60 minute buffer into all Haneda airport transfers on these dates. If the principal's schedule permits, consider advising use of Narita Airport or Tokyo Station Shinkansen connections as alternatives.

Fukuoka

Hakata Dontaku Harbor Festival 2026 — May 3–4, 2026 (Eve Festival: May 2, 17:00–20:30)

  • Area: Hakata District, central Fukuoka City. Dontaku Parade route: Meiji-dori (Gofukumachi to Tenjin, approximately 1,270 metres). 30+ stage venues across the city.
  • Expected impact: One of Japan's largest festivals — approximately 2 million visitors over 2 days in normal years. This is the 65th postwar revival year (theme: "80 Years Since the Revival"). Tenjin and Hakata districts will be at maximum capacity on May 3–4. All transit (Fukuoka Subway, JR Hakata Station) and roads through central Fukuoka will be severely congested. Formal road closures along the Meiji-dori parade route are in effect during afternoon parade hours.
  • Source: Fukuoka Now | Visit Fukuoka (Crossroad Fukuoka) | Japan Cheapo
  • Operational note: Hakata Dontaku draws approximately 2 million visitors and is Japan's most widely attended single festival event. EP teams in Fukuoka on May 3–4 should avoid routing principals through Tenjin or Meiji-dori during parade hours (approximately 13:00–18:00). For airport transfers to/from Fukuoka Airport (FUK), use the Subway Kuko Line — but anticipate heavy boarding congestion at Hakata Station. Crowd density in central Tenjin will reach levels comparable to major Tokyo crowd events; full crowd safety protocols apply.

Toyama

Tonami Tulip Fair 2026 — April 22 – May 5, 2026 (09:00–17:30; last entry 17:00)

  • Area: Tonami Tulip Park, Tonami City, Toyama Prefecture. Approximately 3.5 million tulips across 300+ varieties on display.
  • Expected impact: Japan's largest tulip festival, coinciding fully with Golden Week. Heavy tourist traffic to Tonami City expected during April 29 – May 5. Toyama Chiho Railway and JR Johana Line to Tonami Station will be crowded. Local roads around Tonami Tulip Park will be congested throughout Golden Week.
  • Source: Tonami Tulip Fair Official | Japan Guide
  • Operational note: For EP teams accompanying principals to the Tonami area during Golden Week: pre-arrange designated drop-off and pick-up points away from the main park gates, as parking areas and access roads become gridlocked by mid-morning. Approach before 10:00 or after 16:00 for minimum congestion. Crowd density within the park itself is manageable given its large outdoor scale.
