The Ōsumi Peninsula (大隅半島, Ōsumi Hantō) projects south from the Japanese island of
Kyūshū and includes the southernmost point on the island,
Cape Sata.[1] Its east coast lies on the
Pacific Ocean, while to the west it faces the
Satsuma Peninsula across
Kagoshima Bay. Politically it is part of
Kagoshima Prefecture. Lava erupted in 1914 by
Sakurajima (previously an island) made a land connection with the northwest of the Ōsumi Peninsula.
