Japanese midget submarine HA-19 was one of five submarines that attacked Pearl Harbor on that morning each with a crew of two and carrying two torpedoes.

HA-19’s gyrocompass malfunctioned and she ran aground outside the entrance to Pearl Harbor and was captured.

Ensign Kazuo Sakamaki, the boat commander, survived while his crewmate drowned. Sakamaki became the first Japanese prisoner of war. Included in the display are photos of Ensign Sakamaki, internment documents, and images of HA-19 aground. Postscript: in 1991, Sakamaki visited the National Museum of the Pacific War for its annual Symposium and was reunited with HA-19.
