Japan has returned to using the prewar name for the island of Iwo Jima at the urging of its original inhabitants, who want to reclaim an identity they say has been hijacked by high-profile movies like Clint Eastwood's "Letters from Iwo Jima."

The old name, Iwo To, was adopted Monday by the Japanese Geographical Survey Institute in consultation with Japan's coast guard.

Surviving islanders evacuated during the war praised the move, but others said it cheapens the memory of a brutal campaign that today is inextricably linked to the words Iwo Jima.

Back in 1945, the small, volcanic island was the vortex of the fierce World War II battle immortalized by the famous photograph by Joe Rosenthal of The Associated Press showing Marines raising the American flag on the islet's Mount Suribachi.

Before the war, the isolated spit of land was called Iwo To — pronounced "ee-woh-toh" — by the 1,000 or so people who lived there. In Japanese, that name looks and means the same as Iwo Jima — Sulfur Island — but it has a different sound.

The civilians were evacuated in 1944 as U.S. forces advanced across the Pacific. Some Japanese navy officers who moved in to fortify the island mistakenly called it Iwo Jima, and the name stuck. After the war, civilians weren't allowed to return and the island was put to exclusive military use by both the U.S. and Japan, cementing its identity.

Today Iwo To's only inhabitants are about 400 Japanese soldiers.

The 1945 battle for Iwo Jima pitted some 100,000 U.S. troops against 22,000 Japanese deeply dug into a labyrinth of tunnels and trenches. Nearly 7,000 Americans were killed capturing the island, and fewer than 1,000 of the Japanese survived.
