It draws many tourists who come to eat the octopus and blowfish caught off the island and prepared there, to enjoy the onsen, to fish, or to spend time on the beach.

The total area of the island is 0.77 square kilometers, of which approximately half is owned by the Imperial Household Agency.

During the Edo period, it was part of the holdings of Owari Domain under the Tokugawa shogunate and contained a fishing settlement.

With the establishment of the modern municipalities system after the start of the Meiji period, the island was organized as a village within Chita District, Aichi.

From Kōwa Station, visitors can board a bus which will take them to a high-speed boat which will take them to the island in about ten minutes.
