38% of evacuation centers in central Tokyo, 20 major cities in expected flood areas
As many as 38 percent of current and planned public evacuation centers are located in severe flooding danger areas in the 23 wards of Tokyo and 20 designated cities with a population of 500,000 or more, a Mainichi Shimbun poll of the municipalities has found.
Half of the capital's evacuation centers, especially those in eastern parts of the city below sea level, would be submerged in a flood caused by a one-in-a-millennium-scale rainfall. In the case of Osaka in western Japan, more than 80 percent of such facilities face the risk of flooding if the Yodo and Yamato rivers flooded.

By area, 70 percent of evacuation centers in the city of Niigata on the Sea of Japan coast are expected to be submerged due to the flooding of the Shinano and other local rivers in the event of catastrophic rainfall. The same ratio of centers in Kawasaki south of Tokyo would be flooded should the Tama River overflow. Meanwhile, inundations are projected to hit 50 percent of evacuation sites in Kyoto, western Japan, and 40 percent in the cities of Saitama, north of Tokyo, Hamamatsu and Nagoya in central Japan, and Kumamoto in southern Japan.
Among the capital's 23 wards, all designated evacuation centers in Adachi and Katsushika would be flooded. The ratio is more than 90 percent in Arakawa, Edogawa and Sumida, and more than 80 percent for Koto, Taito and Chuo -- mostly in eastern Tokyo.
