Typhoon Man-yi

Typhoon Man-yi was a powerful tropical cyclone that struck Japan in September 2013, causing widespread disruption across the Pacific Ocean basin and prompting emergency responses from national and local authorities. The system evolved from a tropical disturbance near the Mariana Islands before intensifying en route to the Ryukyu Islands, the Kanto region, and the Hokuriku region, producing strong winds, heavy rainfall, and coastal storm surge. The storm affected transportation networks including the Tokaido Shinkansen, prompted evacuations in Chiba Prefecture and Kanagawa Prefecture, and was analyzed by agencies such as the Japan Meteorological Agency and the Joint Typhoon Warning Center.

Meteorological history

Man-yi originated as a tropical disturbance southeast of the Mariana Islands within a monsoon trough associated with the Western Pacific seasonal convective activity. The Japan Meteorological Agency and the Joint Typhoon Warning Center monitored consolidation of convection as environmental shear decreased and sea surface temperatures near the Philippine Sea remained anomalously warm. The system attained tropical storm status while moving northwestward, later undergoing rapid deepening influenced by an upper-level anticyclone linked to the Subtropical Ridge. Interaction with mid-latitude westerlies and a developing baroclinic zone near the Korean Peninsula induced an eventual recurvature northeastward toward the Kii Peninsula, where extratropical transition began as it encountered the Oyashio Current and cooler waters. Operational estimates by the Meteorological Satellite Center and best-track analyses by the International Best Track Archive for Climate Stewardship placed peak intensity with minimum central pressure under 950 hPa and maximum sustained winds consistent with typhoon classification.

Preparations and warnings

Advance warnings were issued by the Japan Meteorological Agency in coordination with prefectural disaster management offices in Kyoto Prefecture, Hyōgo Prefecture, Mie Prefecture, and the Greater Tokyo Area. The Ministry of Land, Infrastructure, Transport and Tourism mobilized flood defenses and advised riverbank reinforcements along the Kiso River and Tone River, while municipal governments in Chiba Prefecture and Saitama Prefecture initiated voluntary evacuations for residents in designated evacuation centers such as municipal schools and gymnasiums. Transportation operators including East Japan Railway Company and Central Japan Railway Company suspended services on the Tokaido Shinkansen and regional lines; aviation authorities affected airlines like Japan Airlines and All Nippon Airways resulting in cancellations at Haneda Airport and Narita International Airport. The Self-Defense Forces and local fire departments stood by for search-and-rescue, and the Red Cross Society of Japan prepared relief supplies.

Impact

Man-yi caused casualties and structural damage across multiple prefectures, with fatalities reported in urban and rural settings. Heavy precipitation triggered landslides near the Noto Peninsula and river flooding in the Kantō and Hokuriku regions, impacting communities in Ishikawa Prefecture and Niigata Prefecture. Coastal storm surge and high waves damaged seawalls and ports including facilities in Kanagawa Prefecture and disrupted fishing fleets registered in Fukuoka Prefecture. Widespread power outages affected households served by utilities such as Tokyo Electric Power Company and Hokuriku Electric Power Company, while agricultural losses were reported for rice paddies and orchards in Aomori Prefecture and Akita Prefecture. The storm impeded major sporting events and cultural festivals across Osaka and Yokohama, and triggered emergency declarations in several municipal jurisdictions. Economic impacts influenced freight operations for conglomerates including Mitsubishi Heavy Industries and supply-chain interruptions for manufacturers in the Chubu region.

Aftermath and recovery

Following landfall and dissipation, recovery efforts involved interagency coordination among the Cabinet Office (Japan), prefectural governors, and municipal mayors to restore infrastructure and provide temporary housing. The Self-Defense Forces assisted with debris removal and water distribution, while non-governmental organizations such as the Japanese Red Cross Society and Peace Winds Japan delivered humanitarian assistance. Restoration of rail service by operators like West Japan Railway Company and utilities by companies including Tohoku Electric Power Company proceeded under accelerated timetables, with engineers repairing damaged bridges on national routes managed by the Ministry of Land, Infrastructure, Transport and Tourism. Reconstruction grants and disaster relief pensions were administered under frameworks involving the Diet of Japan and local assemblies, and lessons from the event informed updates to municipal hazard maps and evacuation protocols in prefectures such as Chiba and Kanagawa.

Records and naming

The name assigned by the ESCAP/WMO Typhoon Committee followed the established naming protocol used across the Western North Pacific basin; Man-yi was contributed by Hong Kong and is associated with a local geographic reference. The storm's rapid intensification phase and track near major population centers drew comparison in operational records maintained by the Japan Meteorological Agency, the Joint Typhoon Warning Center, and the National Institute of Informatics datasets. Meteorologists compared barometric minima and wind profiles to historical events cataloged in the International Best Track Archive for Climate Stewardship and in national records such as the Data Integration and Analysis System of Japan.

Seasonal context and comparison

Man-yi occurred during the 2013 Pacific typhoon season, a year featuring multiple notable systems including Haiyan-class events and several damaging cyclones that affected the Philippines, Taiwan, and the Korean Peninsula. Seasonal drivers included a neutral-to-weak El Niño–Southern Oscillation phase and intraseasonal variability tied to the Madden–Julian Oscillation, which modulated convective activity in the Western Pacific. Climatologists compared Man-yi's impacts and track to prior Japanese landfalls such as storms studied in the aftermath of Typhoon Talas (2011) and Typhoon Wipha (2013), incorporating findings into broader assessments by institutions like the Meteorological Research Institute and international collaborations including the World Meteorological Organization.
