ww2dbaseHa-19, a 47-ton Type A midget submarine, was built at Kure, Japan, in 1938. Between late Nov and early Dec 1941, she was transported aboard the larger submarine I-24 to the waters off Pearl Harbor, Hawaii, United States where she was one of five midget submarines launched to participate on the 7 Dec Japanese raid.

ww2dbaseA non-functioning gyrocompass prevented Ha-19 from entering Pearl Harbor. After many adventures, she went aground at Waimanalo, on the east coast of Oahu. The submarine and her pilot, Ensign Kazuo Sakamaki, were captured on 8 December. Ensign Sakamaki was the first Japanese prisoner of war taken by the United States during the Pacific War.

ww2dbaseHa-19 was salvaged and later sent to the United States' mainland, where she was featured at War Bond drives throughout the country. After the end of the war she was exhibited for many years at Key West, Florida, United States. In 1991, Ha-19 was moved to Fredericksburg, Texas, United States, where she remains on display at the Admiral Nimitz museum.
