Fumizuki is a Mutsuki-class destroyer of the Imperial Japanese Navy, launched in 1926 and sunk in Chuuk Lagoon in 1944. The wreck still carries its bow and stern guns and a torpedo launcher, the reason divers visit it.

Also known as Fumitsuki, Fumitzuki, Fumitzuki Destroyer, Fumitsuki Maru.

The dive

Dives on the 98 m (320 ft) destroyer stay between 24 and 37 m (80 and 120 ft). Its armament is the point of the dive: guns at the bow and at the stern and, between them, a torpedo launcher.

Fumizuki was laid down at the Fujinagata Shipyards in Osaka on 20 October 1924, launched on 16 February 1926 and completed on 3 July 1926. At Truk on 17 February 1944, during Operation Hailstone, a Grumman TBF Avenger's bomb landed close enough to disable her turbine, and she flooded and sank on 18 February 1944.
