Disaster-ravaged northern Japan has now been overwhelmed by floods. At least one person is known to have died and 300 000 have been warned to leave their homes. This is the weather system that has already killed dozens on the Korean peninsula.
Forecasters are warning that the torrential rain is likely to continue.
Sanjo City is the regional capital of Nigata Prefecture. More than 600 millimetres of rain have fallen in the city since Wednesday. One man in Fukushima was caught in a mudslide as he built a sandbag barrier to hold off the floods.
Experts have warned the the quake-hit areas are more prone to mudslides, as the shaking has weakened the topsoil.
