Lat 24°47′N Long 141°19′E  Iwo Jima 硫黄島 is part of the Volcano Islands in Ogasawara Subprefecture in Japan. In Japanese, Iwo To or Iwo Jima means "Sulfur Island". Surrounded by the North Pacific Ocean, the island is less than five miles long and two and a half miles wide at its widest point and has been described by many as pork chop shape when viewed from the air and has no source of potable water. Located 80 km to the north is North Iwo Jima (Kita Iwo Jima). Iwo Jima is located south and west of the midpoint between Tokyo on Honshu in Japan and Saipan in the Mariana Islands.

In Japanese, Iwo To or Iwo Jima means "Sulfur Island". Prewar and in Japan the correct name for the island was Iwo To. During World War II, the Americans referred to the island as Iwo Jima. Postwar, many Japanese referred to as Iwo Jima by the Japanese.

Wartime History
Roughly 22,000 Japanese defenders prepared defenses and sighted the potential landing beaches with artillery, mortars, rockets and machine guns. The island's radar provided an early warning system and interception point for Japanese aircraft to attack B-29 Superfortresses passing the island returning to the Marianas.

American missions against Iwo Jima
July 4, 1944–February 27, 1945

On February 19, 1945 an amphibious landing by the U. S. Marine Corps (USMC) landed on the invasion beaches on the southern coast of the island near Mount Suribachi. The first day of combat resulted in 2,400 American casualties. During the battle US. Marines, sailors and soldiers killed an estimated 20,000 Japanese and captured over 1,000 prisoners. On March 25, the Battle of Iwo Jima was declared over and the island secured, although mopping up continued until July by the US Army, including the 147th Infantry Regiment. Immediately, the island's airfields were repaired and expanded for American used and for B-29 emergency landings until the official surrender of Japan in September 1945.

During the U. S. occupation of Japan, American forces maintained a presence on Iwo Jima until the end of the Korean War. In 1968, Iwo Jima was returned to Japan and was the last part of Japan under U. S. military control but continued to maintain a small American presence in the form of a U. S. Coast Guard (USCG) station until closed in October 1993.

Since 1968, the Japanese Self Defense Force (JSDF) maintains a base on Iwo Jima including Iwo Jima Airport (Motoyama No. 2, Airfield No. 2, Central Field). Today, Iwo Jima is off limits to outside visitors or tourists, aside for the annual World War II memorial services held once a year.

Invasion Beach
Located on the east coast of the island. Site of the massive American landing on Iwo Jima. The amphibious assault on Iwo Jima was considered to be the "ultimate storm landing," with a striking force of 74,000 Marines. The U.S. Marine 4th and 5th Divisions led the invasion, with the 3rd Division in reserve. After the war, the landing beaches were largely cleared of wreck age which was sold as scrap metal.

Mount Suribachi (Suribachiyama)
555' volcano on the southern end of Iwo Jima, the highest point on the island. The Japanese tunneled a seven-story interior structure. Heavily bombed and napalmed by American aircraft during the assault. The summit was captured on February 23, 1945, sight of the first and second flag raising and memorial

Japanese Bunkers and Tunnels
Prior to the American assault, the Japanese built 16 miles of tunnels into Iwo Jima for defenses and living quarters and a hospital 46' underground. Many of these tunnels were tombs for Japanese defenders killed on the island. In 1984, three mummified Japanese soldiers were discovered in a cave.

General Kuribayashi Bunker (General's Bunker)
Located near the northern end of Iwo Jima. A large tunnel complex that reaches 75' underground with five levels.

Sgt G. W. Rosson recalls from 1946:
"We went all through the General's cave down to the 2nd level. All of the halls 4 by 6 feet would go down at a 60 degree to the next level. The General's cave is 75 feet deep at the bottom floor. Lot of stories of what was in that cave, one small room had a bath tub half way in the ground. One room had chairs and tables all over the place. There were a lot of Japanese paper all over the floor. We went down to the next level it got hotter and the smell was bad. We came to the next opening going down to the next level. Since this was the General's cave we new that there had to be another way out. We found it a big wooden door that we couldn't get open. In one of the rooms there were 8 or 9 dead bodies. The smell was bad, their skin was dried up. There were a lot of air shafts going up."
