Super typhoon could submerge 1/3 of Tokyo
A recent study by the Tokyo Metropolitan Government (Japan) warned that one-third of the city's area could be submerged in floodwaters and nearly four million people would be affected if a super typhoon made landfall in the capital and caused a tsunami.

This is the first assessment of Tokyo's vulnerability to large storm surges, and comes amid rising storm damage globally.
According to the report, 212 square kilometers, or about 30% of the area of the central Tokyo area, could be submerged under 10 meters of floodwater if a super typhoon makes landfall.
Such a powerful storm could affect 3.95 million people, or 25 percent of the city’s 13.7 million residents, local authorities said, submerging the central business and entertainment districts and major railway stations. In particular, the eastern part, near the Arakawa River, could be in a state of constant flooding for a week if large waves breach the river levees of Tokyo Port.
Based on the report's forecast, the Tokyo Metropolitan Government has drawn up plans for evacuation, preventive measures, and reviewed the way it issues storm warnings to local residents.
Severe storms often hit the Land of the Rising Sun, causing landslides and floods, and causing great casualties.
