The Kamishima class minelayer (神島型敷設艇, Kamishima-gata Fusetsutei?) was a class of minelayers of the Imperial Japanese Navy (IJN), serving during and after World War II. 9 vessels were planned under the Maru Sen Programme, however only 1 vessel was completed until the end of war.

Background[]

  • End of 1944, Japanese sea lanes were cut apart by United States Navy. The IJN wanted to secure only the security of the Sea of Japan.
  • Therefore, the IJN had to lay a naval mine in La Pérouse Strait, Tsugaru Strait and Tsushima Strait. However, the IJN already exhausted minelayers.
  • The IJN planned two kinds of minelayers. One was the large-sized Minoo class, the other the small-sized Kamishima class.
