Iwo Jima, officially Iō-tō (硫黄島^?,  listen (help·info): "sulfur island"), is an island of the Japanese Volcano Islands chain, which are south of the Ogasawara Islands and together with them form the Ogasawara Archipelago. The island is 650 nautical miles (750 mi; 1,200 km) south of mainland Tokyo and is administered as part of Ogasawara, one of eight villages of Tokyo (but is presently uninhabited). It is famous as the setting of the February–March 1945 Battle of Iwo Jima between the United States and the Empire of Japan during World War II. The island grew in recognition in the west when the iconic photograph Raising the Flag on Iwo Jima was taken during the battle. The U.S. occupied Iwo Jima until 1968, when it was returned to Japan.

In 1779, the island was charted as Sulphur Island, the literal translation of its official name, during Captain James Cook's third surveying voyage.

General Tadamichi Kuribayashi (栗林 忠道, Kuribayashi Tadamichi^?, born 7 July 1891 in Nagano Prefecture, Japan – c. 26 March 1945 on Iwo Jima, Japan) was a haiku poet, diplomat, and General (Taisho) of the Imperial Japanese Army General Staff. He is best known for being overall commander of the Japanese garrison during the Battle of Iwo Jima.

Even before the battle, General Kuribayashi insisted upon sharing the hardships of his men. He also refused to permit banzai charges, which he regarded as an unnecessary waste of his men's lives. Although the United States military had expected to capture Iwo Jima in 5 days, Kuribayashi and his men waged guerilla warfare against them for 36 days. Although he is believed to have been killed in action in the final assault, Kuribayashi's body was never identified by the Americans.

The 2006 movie Letters from Iwo Jima brought General Kuribayashi's story to an international audience for the first time. Kuribayashi was portrayed by Japanese actor Ken Watanabe. The film received wide acclaim and four Academy Award nominations.
