A powerful typhoon was expected to make landfall somewhere between the Tokai and Kanto regions by early Friday, the Meteorological Agency said.
Typhoon Mawar affected air and ferry services throughout Thursday. Japan Airlines and All Nippon Airways canceled many domestic flights, mainly between Tokyo and western cities.
Passenger ferries between Tokyo and the Izu Islands, as well as those between Nagoya and Tomakomai, Hokkaido, were also canceled.
Japan Railway group companies canceled some train services to and from the Izu Peninsula, Shizuoka Prefecture, and the Kii Peninsula in Wakayama Prefecture, and scrubbed 27 night trains Thursday.
The typhoon was located about 90 km southwest of Irozaki, Shizuoka Prefecture, as of 7 p.m. Thursday and was heading northeast at 20 kph, the agency said.
About 20 mm of rain fell per hour in areas of the Kii and Izu peninsulas Thursday morning, and a maximum wind velocity of about 112 kph was registered in Shionomisaki, Wakayama Prefecture.
