Japanese naval officers who arrived to fortify the island before the U.S. invasion mistakenly called it Iwo Jima. In this way, the "Iwo Jima" reading became mainstream and was the one used by U.S. forces who arrived during World War II. Former island residents protested against this rendering, and the Ministry of Land, Infrastructure and Transport's Geographical Survey Institute debated the issue and formally announced on June 18, 2007, that the official Japanese pronunciation of the island's name would be reverted to the pre-war Iōtō. Moves to revert the pronunciation were sparked by the high profile films Flags of Our Fathers

With the landing area secure, more troops and heavy equipment came ashore and the invasion proceeded north to capture the airfields and the remainder of the island. Most Japanese soldiers fought to the death. On the night of March 25, a 300-man Japanese force launched a final counterattack. The Marines suffered heavy casualties; more than 100 were killed and another 200 Americans were wounded. The island was officially declared "secured" the following day.

Reunion of Honor

On February 19, 1985, the 40th anniversary of the day that U.S. forces began the assault on the island, veterans from both forces gathered for the Reunion of Honor just a few meters away from the spot where U.S. Marines had landed on the island.
During the memorial service a granite plaque was unveiled with the message:

On the 40th anniversary of the battle of Iwo Jima, American and Japanese veterans met again on these same sands, this time in peace and friendship. We commemorate our comrades, living and dead, who fought here with bravery and honor, and we pray together that our sacrifices on Iwo Jima will always be remembered and never be repeated.


It is inscribed on both sides of the plaque, with the English translation facing the beaches where U.S. forces landed and the Japanese translation facing inland, where Japanese troops defended their position.

After that, the Japan-U.S. combination memorial service of the 50th anniversary was held in front of this monument in March 1995. The 55th anniversary was held in 2000, followed by a 60th reunion in March 2005 (see U.S. National Park Service photo below).
