Mutsuki was a Mutsuki-class destroyer of the Imperial Japanese Navy and the flagship of Destroyer Division 30.
In December 1941 she went with the force that attacked Wake Island. Kenji Hatano was her captain for that attack.
On 11 December 1941 she took part in the bombardment during the Battle of Wake Island. On 23 December she was with the landing force. She came through the Wake operation afloat.
Her end came on 25 August 1942, about 40 miles northeast of Santa Isabel. She was standing by the bombed Kinryu Maru, assisting that ship, when Army B-17s sank her.
Forty-one of her men were killed. Credit for the sinking was not given to any one plane. Hatano was relieved on 8 September 1942.
