The {{Nihongo|Ōnohara Islands|大野原島|Ōnohara-jima}} are a group of volcanic deserted islands located in the Philippine Sea approximately {{convert|180|km|mi}} south of Tokyo and {{convert|10|km|mi}} west of Miyake-jima, in the northern portion of the Izu archipelago, Japan.

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 {{convert|114|m|ft}} on the main islet of {{nihongo|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 US Air Force used Ōnohara-jima as a bombing range, endangering the Japanese murrelet, a rare seabird that breeds on Ōnohara-jima. The bombing was stopped after Jack Moyer wrote a letter to an associate of then-US President Harry S. Truman.Gonzales, Mithi Laya S & Shinoke, Hidenori [http://www.birdlife.org/sites/default/files/attachments/Review%20of%20LCGs%20on%20Miyake%20Island%2C%20Japan_FINAL%2020%20Dec%202013.pdf Co-Existing in Harmony with Nature: Local Conservation Groups at Miyake Island IBA, Tokyo, Japan ] Retrieved September 11, 2017Polunin, Nicholas [https://books.google.com/books?id=iWb7AQAAQBAJ&dq=onoharajima+bombing+range&pg=PA224 World Who Is Who and Does What in Environment and Conservation page 224] Retrieved September 11, 2017{{cite web|author1=Stephen Hesse|title='Miyake man' leaves a legacy of inspiration|url=http://www.japantimes.co.jp/life/2004/01/15/environment/miyake-man-leaves-a-legacy-of-inspiration/#.U8bZ5I1dUWE|publisher=The Japan Times|accessdate=11 September 2017}}
