## Geography

Ōnohara-jima consists of nine main islets and several smaller rocks and stacks. The island is the remnant of an andesite lava dome with sheer sides, the only visible portion of a submarine volcanic caldera. The above sea-level portion has a surface area of approximately 0.2 square kilometers, with a summit height of 114 metres (374 ft) on the main islet of Koyasu-shima (小安島).

Located in the Kuroshio Current, the area has abundant sea life, and is popular with sports fishermen and scuba divers.

During the Korean War, aircraft of the United States Air Force used Ōnohara-jima as a bombing range, endangering the Japanese murrelet, a rare seabird. The bombing was stopped after Jack Moyer wrote a letter to an associate of then-US President Harry S. Truman.[1][2][3]
