  ## Demographics
  
  Per Japanese census data, the population of Kōzushima has declined in recent decades.
  
  ## History
  
  Kōzushima Village was founded on October 1, 1923, when the Izu islands were administratively divided into villages and town.
  
  ## Economy
  
  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 its 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.
  
  ## Transportation
  
  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.
  
  ## Education
  
  The village operates one public elementary and one public middle school.
  
  * Kozushima Junior High School (神津島村立神津中学校)
  * Kozushima Elementary School (神津島村立神津小学校)
  
  Tokyo Metropolitan Government Board of Education operates Kōzu High School [ja] , the only high school in the village.
