Hokuyo Maru
Coastal freighter (4,217 t) bombed on 17 Feb 1944; a bomb behind No. 3 hold and a boiler explosion tore twin holes in her starboard side. She sits upright with the superstructure and funnel intact on a seabed at about 60 m, so marine growth is limited and the wreck is rarely dived and strictly technical.

- Tips: Technical-only wreck; plan gas and deco for 55–64 m. Wrecks are war graves – look, photograph, take nothing. Some cargo (shells, mines, bombs) is unstable: do not touch it.
