This underground bunker was used as the headquarters of the Imperial Japanese Navy during the Battle of Okinawa, and was dug in 1944 by a naval installation team of about 3,000 men, the remains of the battle in which 4,000 soldiers fought. Currently, a 300-meter section is open to the public, and the commanding officer's office and operations room remain in their original state. The museum exhibits artifacts and photographs, and is maintained as a battle site park that communicates peace.
This is an underground command post dug by the former Imperial Japanese Navy for the defense of Oroku Airfield (now Naha Airport) in 1944, at the end of the Pacific War, in preparation for the landing of U.S. forces. Approximately 3,000 men of the 226th Naval Expeditionary Unit dug the dugout with pickaxes and a circular spoon, and completed it in December of the same year. Up to 4,000 soldiers holed up in the dugout, which served as a command center for fierce ground fighting until June 13, 1945, when Commander Minoru Ota and his men committed suicide.
In the 300m dugout open to the public, the commander's office, operation room, staff room, code room, medical room, etc. remain as they were in those days. The walls are covered with grenade holes and pickaxe marks, showing the tragedy of the Battle of Okinawa. In the museum on the ground, Commander Ota's telegram to the Vice Minister of the Navy, "Okinawa Prefecture Citizens Shikusen Heri," as well as artifacts, photographs, and paintings are on display.
The area around the bunker has been developed as a naval bunker park, with a cenotaph and observation plaza. Many visitors come here on school trips and for peace education, and the park is well known as a war site park that transmits the message of lasting peace from Okinawa to the world.
