In December 1945
U. S. Marines occupied the Bonin Islands including Chi Chi Jima and destroyed
and burned all equipment and buildings of military value to demilitarize the island. During 1946, a US Navy facility was established on the island and operated until the 1960s.
During 1947 a war crimes trial on Guam prosecuted by USMC Colonel Presley M. Rixey tried those responsible for these crimes, but received little press in the United States. The Japanese found guilty were hanged and buried in unmarked graves on Guam. Executed were Japanese Army General Yoshio Tachibana and Major Sueo Matoba who ordered the executions. Lt. Col. Kikuji Ito and Captain Noburu Nakajima who executed prisoners were executed.
Others were given prison sentences including Lt. Morishita who beheaded a prisoner.
During the 1980s, Chi Chi Jima was returned to Japan. Today, the island is a resort area for divers and vacationers from Japan.

Yoake and Mount Asahi Radio Stations
Mount Yoake and Mount Asahi are the two two highest peaks on Chi Chi Jima. The Japanese Navy
built an array of short and long range radio receivers and transmitters
at the summit of each mountain defended by anti-aircraft guns. These communications facilities were used to relay
messages and eavesdrop on American communications. Although targeted by American
aircraft, the facility was never substantially damaged. On September 2, 1944 TBM
Avenger 46214 piloted by Lt(jg) George H. W. Bush was damaged and crashed offshore. In 1946, American occupation forces dynamited the roof the the radio facility, collapsing it.
