is a village located in Ōshima Subprefecture, Tokyo Metropolis, Japan., the village had an estimated population of 1,841, and a population density of 99 persons per km2. Its total area is 18.58sqkm.
Kōzushima Village covers the islands of Kōzu-shima, one of the northern islands in the Izu archipelago in the Philippine Sea, 178km (111miles) south of central Tokyo. Warmed by the Kuroshio Current, the town has a warmer and wetter climate than central Tokyo.
Per Japanese census data,[1] the population of Kōzushima has declined in recent decades, since 1990.
Kōzushima Village was founded on October 1, 1923, when the Izu islands were administratively divided into villages and town.
The village economy is dominated by commercial fishing and seasonal tourism. There is also some small-scale farming. In the middle of the 20th century, unsuccessful attempts were made to develop silkworm farming. Many tourists come for sports fishing and scuba diving. Its white sandy beaches make it an excellent place to swim in summer, since it receives considerably fewer visitors than the other islands in the Izu chain. There are many hiking courses around Kōzu-shima's volcano, Tenjō-san, which dominates the center of the island. However, winter visits are discouraged, cancellation of flights and ferries due to inclement weather can strand visitors. The island is also noted for its local Shōchū.
Kōzushima is accessible by ferry from mainland Tokyo, Shimoda, Shizuoka, or other Izu Islands.There are also daily flights from Chōfu Airport, in western Tokyo to Kozushima Airport.
The village operates one public elementary and one public middle school.
Tokyo Metropolitan Government Board of Education operates http://www.kouzu-h.metro.tokyo.jp/, the only high school in the village.
