Typhoon Jangmi (also known as Typhoon No 6) moved northwards over the course of this week. From Okinawa to mainland Japan, prolonged and heavy rainfall led to landslide warnings and the flooding of rivers, with Japan issuing level 4 warnings for some rivers, signalling a risk of overflowing. This level is high enough for municipalities to issue evacuation orders. Three-hourly rainfall totals on Wednesday reached 105mm in Chiyoda, Tokyo, which was a record high for the month. Sustained wind speeds of 80mph (130kph) were recorded on Monday – making it a category 1 typhoon – bringing damage and disruption to businesses, transport, infrastructure and the environment.
By Wednesday, 23 people had been injured, 17 of whom were in Okinawa. The typhoon damaged 57 homes and led to 60,000 homes losing electricity. In addition to this, 1.52 million people were advised to evacuate by authorities. The typhoon damaged the exterior wall of Himeji Castle, a Unesco world heritage site in western Japan. The maximum recorded wind speed at Himeji was 56mph, according to the Japan Meteorological Agency. The typhoon has now weakened into a tropical depression and has moved eastwards, away from the islands.
