On the island of Kiska, Alaska, an abandoned Japanese midget submarine has lain silent in the grass that has consumed its former launch facility for decades. The abandoned wreck is now part of a Pacific war memorial.
“Japanese Type A midget submarine beached in eastern Oahu, after it unsuccessfully attempted to enter Pearl Harbor during the 7 December 1941 Japanese attack. The photograph was taken on or shortly after 8 December 1941.” (NHHC: 80-G-32680)
At the end of World War II, Allied Occupation forces found hundreds of midget submarines built and building in Japan, including large numbers of the “Koryu” type. Many of these boats were in massed groups at shipyards and naval bases.
