The storm brought heavy rainfall and gusty winds, disrupting traffic in extensive areas. Some 1 500 homes in Ibaraki prefecture, north of Chiba, have lost power until morning. 

TEPCO said Chanthu has also moved over the crippled Fukushima Daichi Nuclear Power Plant, but nothing unusual was reported and activity remains the same today, WestPacWx reported.

Most of the Fukushima prefecture is under a landslide warning.
