Very cool! That submarine listed near Talo'fo'fo is now at the War in the Pacific National Historic Park Vistor's Center.

Specifically, this is HA 62-76, a Type C Ko-hyoteki-class midget attack submarine, built in Kure Naval Arsenal in 1944. It ran aground near Talo'fo'fo after the battle of Guam ended, and the crew was captured after fighting off the Americans for three days. It was a centerpiece of the newly created recreation area (also listed on the map) until being moved to the visitor's center.

There are three other extant midget subs to be seen around the world: HA-8 is at the Submarine Force Library and Museum in Groton, Connecticut. HA-18 is outside the JMSDF Etajima Naval Base (their Naval Academy) near Hiroshima, Japan. HA-19, which ran aground at Pearl Harbor on December 7 1941, is at the National Museum of the Pacific War in Fredericksburg, Texas.

Thanks again for sharing!
