Mount Suribachi (摺鉢山, Suribachiyama) is a 169-metre (554 ft)-high mountain on the southwest end of Iwo Jima in the northwest Pacific Ocean under the administration of Ogasawara Subprefecture, Tokyo Metropolis, Japan.

[citation needed] Joe Rosenthal's iconic World War II photograph, Raising the Flag on Iwo Jima, depicting United States Marines raising an American flag, was taken at the mountain's peak during the Battle of Iwo Jima in 1945.

[2] The Japanese Meteorological Agency reported that on May 2, 2012, a small eruption caused water discoloration to the northeast, and confirmed the appearance of a new fumarole.

[1] During World War II, the Japanese built tunnel and bunker systems in and on Mount Suribachi.

For the United States, Iwo Jima was an important strategic point between the United States and mainland Japan, needed for its close proximity to Japan as an airstrip for supporting aircraft in Japanese mainland bombing operations but became useful for damaged B-29s returning to the Mariana Islands from bombing Japan, a status that resulted in severe fighting that led to over 20,000 American casualties and close to 20,000 Japanese killed.
