Typhoon Jangmi (No. 6) Strikes Japan: Landfall, Damage, and Disruption

Typhoon No. 6, Jangmi (チャンミー), made landfall in Japan on Wednesday, June 3, 2026, triggering widespread damage across a broad swath from western to eastern Japan. According to Kiolix Pulse's Google Search trend data, searches for "台風" (typhoon) in 🇯🇵 Japan have surpassed 1 million, placing the topic firmly at the top of the country's trending search list.

Track and Current Status

Jangmi made landfall near the southern coast of Wakayama Prefecture at approximately 4:30 a.m. on June 3. According to the Japan Meteorological Agency (JMA), a June 3 landfall is the fourth-earliest on record since statistics began in 1951. The last typhoon to make landfall in Japan was Typhoon No. 15 in September of the previous year.

As of 7:00 a.m. on June 3, the storm's center was located near Shima City (志摩市), moving north-northeast at approximately 45 km/h. Central pressure stood at 980 hPa, with maximum sustained winds of 25 m/s near the center. JMA forecast the center to reach east of the Kanto region by 6:00 p.m. the same day, and to move off Japan's eastern coast by 6:00 a.m. on June 4, after which the system is expected to transition into an extratropical cyclone.

The name Jangmi (장미) was proposed by South Korea and means "rose" in Korean. Typhoon names are drawn from a pool of 140 names submitted by member states and territories of the ESCAP/WMO Typhoon Committee, assigned in order of formation.

Notably, 2026 has seen a typhoon form in every month from January through May — only the third time this has occurred since records began in 1951, following 1965 and 2015.

Damage by Region

Okinawa (沖縄)

Okinawa bore the initial brunt of Jangmi as it passed near the prefecture on June 1–2. Storm damage was reported across the island — downed trees, toppled utility poles, and damaged vehicles were documented in Naha and surrounding areas. According to Okinawa's prefectural disaster task force, at least 16 people sustained minor injuries, and one worker responding to the outage suffered a serious electric shock and was rendered unconscious. At peak impact, 27 municipalities and 16,080 households lost power; as of June 3, approximately 1,950 households remained without electricity. Mozuku seaweed farms in Katsuren were reported to have suffered near-total crop losses.

Wakayama and Shikoku (和歌山·四国)

A Level 5 flood special warning — the highest tier in Japan's alert system — was issued for Kushimoto Town (串本町) in Wakayama Prefecture. In neighboring Kozagawa Town (古座川町), the Kozagawa River was confirmed to have flooded, prompting a Level 5 "Emergency Safety Action" order at 5:50 a.m. on June 3 covering 16 districts, 862 households, and 1,672 residents downstream from the Aise district.

In Tokushima Prefecture, part of Anan City received the same Level 5 emergency order, and a flood danger warning was issued for the Katsuura River (勝浦川). There were also warnings of potential senjō kōsuitai (線状降水帯) formation over Shikoku — a phenomenon in which an elongated band of intense convective cells develops and repeatedly drenches the same area with extreme rainfall.

Tokai and Kinki (東海·近畿)

As Jangmi tracked eastward across Honshu, Owase City (尾鷲市) in Mie Prefecture recorded a 24-hour rainfall total exceeding 500 mm — a record-setting figure for June. Aichi Prefecture was placed under a severe storm warning, with forecast accumulations reaching up to 250 mm and renewed risk of senjō kōsuitai formation. The storm's peak rainfall coincided closely with morning rush hour, compounding transportation disruption.

Kanto (関東)

The Kanto region faced a separate but overlapping threat: a front extending northward from the typhoon's center generated particularly intense rainfall ahead of the storm's closest approach. Forecasters noted that mountainous areas of western Tokyo could see 200–300 mm of rain in 24 hours — compared to the city's average June monthly total of roughly 168 mm. A Level 4 imminent flood warning was issued for the Meguro River (目黒川) in Tokyo.

Transportation Disruptions

The surge in searches for terms such as "JR東海 計画運休" (JR Central planned service suspension), "jr東日本 運行情報" (JR East service updates), "台風 電車" (typhoon train), and "東京メトロ" reflects acute public concern about transit. JR Central announced planned suspensions on the Tokaido Shinkansen and other key lines, while JR East and Tokyo Metro issued real-time service updates. Multiple departures from Haneda Airport were also cancelled.

Why "台風 米軍" Is Trending

Among the most-searched related terms are "台風 米軍" (typhoon U.S. military) and "台風6号 進路 米軍." These refer to the track forecasts published by the U.S. military's Joint Typhoon Warning Center (JTWC), which many people in Japan consult alongside JMA guidance, particularly when a storm's path is uncertain or when it is approaching populated areas.
