TOKYO, June 2 (Xinhua) -- A severe tropical storm is moving north toward Japan's southwestern island of Kyushu on Tuesday after bearing down on Okinawa the previous day, the country's weather agency said.

As of 7 a.m. local time, Typhoon Jangmi, the season's sixth typhoon, was located west-northwest of Amami-Oshima Island between Kagoshima and Okinawa prefectures and moving north-northeast at a speed of about 25 km per hour, the Japan Meteorological Agency (JMA) said.

Over 10 people were injured in Okinawa Prefecture amid strong winds, public broadcaster NHK reported.

Airlines have canceled over 320 flights in and out of Kyushu and elsewhere on Tuesday, while Shinkansen bullet trains could also be affected, with the Tokaido line facing possible disruptions from Tuesday night into Wednesday, the report said.

The JMA is cautioning against strong winds and heavy rain, citing the potential for landslides, floods in low-lying areas and overflowing rivers in the Amami region on Tuesday and in western Japan from Tuesday into Wednesday. ■
