The Japan Meteorological Agency called for vigilance across the Kanto region as the ninth typhoon of the season looked set to pound the Izu island chain south of Tokyo as early as Aug. 1.
It warned of strong winds and high waves, as well as landslides and swollen rivers due to heavy rain.
The typhoon was slowly moving northward over the Pacific Ocean and situated about 320 kilometers north-northeast of Chichijima island, part of the Ogasawara island chain far to the south of Tokyo, as of 6:45 a.m. on July 31, according to the agency.
With a central atmospheric pressure of 980 hectopascals, the typhoon was generating maximum wind speeds of 90 kph and maximum instantaneous wind speeds of 126 kph.
Heavy rain is expected in the Izu island chain and the Kanto region on Aug. 1 to 2 due to developed rain clouds around the typhoon.
Up to 200 millimeters of rain was forecast for the Izu island chain in the 24 hours through 6 a.m. on Aug. 2. The figure for the Kanto region was 120 mm.
Waves cresting as high as 7 meters accompanied by swells are also forecast in both areas.
