Typhoon Jebi (2018) Typhoon Jebi was a powerful Pacific tropical cyclone that struck Japan in early September 2018, becoming the costliest typhoon in Japanese history. Rapid intensification near the Philippine Sea led to a Category 5-equivalent peak before recurving toward Kansai Airport and Osaka Bay, causing widespread damage across Shikoku, Honshu, and Hokkaido.

Meteorological history

Jebi originated from a tropical disturbance linked to the monsoon trough east of the Philippine Sea and was monitored by the Japan Meteorological Agency and the Joint Typhoon Warning Center; early advisories referenced synoptic-scale interactions with an upper-level trough and the Kuroshio Current. The system consolidated into a tropical depression as tracked by the Philippine Atmospheric, Geophysical and Astronomical Services Administration and later intensified due to low vertical wind shear and high sea surface temperatures influenced by the Pacific Ocean warm pool and the El Niño–Southern Oscillation. Rapid intensification produced an eye feature visible on Himawari-8 imagery and reached peak intensity with a minimum central pressure comparable to notable events like Typhoon Haiyan and Typhoon Tip. A mid-latitude trough and interaction with the Kuroshio Extension steered the system northward; prior to landfall, extratropical transition processes occurred as the cyclone interacted with the East China Sea baroclinic zone and the Oyashio Current.

Preparations and warnings

Japanese authorities, including the Japan Meteorological Agency and local prefectural governments in Osaka Prefecture, Hyōgo, Kobe, and Wakayama, issued evacuation advisories and storm surge warnings for communities around Osaka Bay and the Seto Inland Sea. Transportation operators such as JR West, All Nippon Airways, and Japan Airlines suspended services across key hubs including Kansai International Airport and the Tōkaidō Shinkansen corridor; ports and ferry operators like Kawasaki Heavy Industries and regional shipping companies canceled sailings. Emergency management agencies coordinated with Japan Self-Defense Forces units, and utilities including Tokyo Electric Power Company and regional water authorities pre-positioned crews. The International Olympic Committee and sports federations monitoring events in the region adjusted schedules, while corporate entities such as Panasonic, Sony, and Toyota activated continuity plans for facilities in affected prefectures.

Impact

Jebi produced destructive storm surge and wind impact along the Osaka Bay coastline, inundating parts of Kansai International Airport and causing closure of runways and terminal flooding that affected carriers like Delta Air Lines, Korean Air, and Cathay Pacific. Urban centers including Osaka, Kobe, and Kyoto experienced structural damage to ports, bridges such as the Akashi Kaikyō Bridge corridor, and maritime assets including container ships registered to flags like Panama and Liberia; one cargo vessel struck the Sky Gate Bridge R at Kansai, severing the airport link. Agriculture in Shikoku and Hokkaido sustained losses affecting producers represented by organizations like the National Federation of Fisheries Cooperative Associations and the Japan Agricultural Cooperatives. Energy infrastructure owned by companies such as Kansai Electric Power Company and transport networks including West Japan Railway Company and regional airports suffered outages and service suspensions. Casualties included fatalities and many injuries reported by municipal authorities in Osaka Prefecture and Kobe, while damage estimates later exceeded figures from storms like Typhoon Mireille.

Aftermath and recovery

Recovery efforts involved coordination between municipal governments, Ministry of Land, Infrastructure, Transport and Tourism, and national emergency responders, with reconstruction of critical infrastructure at Kansai International Airport prioritized alongside repair to the Hanshin Expressway and port terminals such as Osaka Port. Supply chain disruptions affected manufacturers including Canon, Hitachi, and Mitsubishi Heavy Industries, prompting interim logistics rerouting by shipping lines like Mitsui O.S.K. Lines and NYK Line. Insurance firms such as Sompo Japan Insurance and Tokio Marine processed claims, contributing to the aggregate economic loss assessments by the Bank of Japan and international reinsurance markets like Munich Re and Swiss Re. Long-term mitigation planning referenced best practices from events including Great Hanshin earthquake recovery and coastal defenses modeled after projects in Netherlands and United Kingdom.

Records and naming

Meteorological agencies recorded Jebi as one of the most intense typhoons to make landfall in Japan since instrumental records that include events like Typhoon Vera; the system set local records for central pressure and storm surge in parts of Osaka Bay and for rapid intensification rates comparable to Hurricane Patricia (2015). The World Meteorological Organization Typhoon Committee naming list provided the designation contributed by Korea; the name originates from a term meaning "swallow" in the contributing language and followed naming conventions used alongside entries like Typhoon Mangkhut and Typhoon Trami.

International response and aid

International assistance and offers of support came from neighboring states and international organizations including United States, China, South Korea, Australia, the United Nations Office for the Coordination of Humanitarian Affairs, and the International Red Cross and Red Crescent Movement. Multinational logistics providers such as Maersk and DHL participated in relief shipments, while foreign airlines including Emirates and Air France adjusted flight schedules to aid repatriation and cargo movements. Technical exchanges on disaster resilience involved institutions like the World Bank, the Asian Development Bank, and research centers such as the International Research Institute for Climate and Society and University of Tokyo disaster science programs.
