Typhoon Wipha has pummelled central Japan, bringing stong winds, record rainfall, landslides and flooding.
At least 14 people have died and more than 50 people are missing.
Many of the dead were buried in mudslides or crushed as buildings collapsed.
Izu Oshima was in the direct path of the typhoon, triggering a landslide that caused part of a volcano to cave-in, destroying more than 30 homes.
At the crippled Fukushima nuclear plant, operators pumped out rain water near storage tanks contaminated by radiation.

"We have held a meeting of the relevant ministries and will do everything in our power to deal with this situation."
Tokyo's Fire Department rescue team has been despatched, as rescuers struggle to access many areas.
The capital was largely spared from damage. Though there was still disruption, as flights were cancelled, bullet train services suspended and schools closed.
(SOUNDBITE) (Japanese) COMMUTER, MISUZU SUSAKI, SAYING:
"It's indeed scary, the wind and everything. It's incredible, there's tornados and mudslides. Natural disasters are just scary."
Typhoon Wipha is expected to move north-east and weaken later on Wednesday.
