Ogasawara Subprefecture

Ogasawara Subprefecture is a subtropical archipelago within Tokyo Metropolitan area, comprising more than 30 islands scattered across Pacific waters. The island group sits roughly 1000 kilometers south of central Tokyo.

The archipelago remained unpopulated until the 1830s, when settlers from Hawaii, America, and Europe established the first permanent settlement under British administration. This early founding shaped the islands' demographic and cultural makeup.

Residents speak Bonin English, a creole language that developed when early settlers and Japanese inhabitants came into contact. This linguistic blend shapes the everyday life and sense of belonging in the community today.

Reaching the islands requires a 24-hour boat journey aboard the Ogasawara Maru from Tokyo, as air travel is not currently an option. Plan accordingly when organizing your visit.

Only two islands, Chichijima and Hahajima, are inhabited, while three remote islets function as critical stations for weather and marine research. These smaller islands play a vital role in scientific observations of the region.
