The No.8 minesweeper (第八号掃海艇, Dai Hachi Gō Sōkaitei), also sometimes called W-8 was a No.7 class minesweeper owned and operated by the Imperial Japanese Navy during World War II, and one of only two W-7 class minesweeper to survive World War II. The ship was laid down on 11 December 1937, and completed on 15 February 1939. Upon completion, it was registered with the Sasebo Naval District. After making it through World War II with fairly little damage, the ship was scuttled by the Royal Navy in the Strait of Malacca on 13 July 1946.
