The Hirokawa Maru was a cargo ship for the Kawasaki Line before she began her military career, cut short by a American raid on November 14th, 1942.  She was sunk off a white sand beach just north of Honiara where she lies today, semi exposed.  Despite the shallow waters in which she rest and numerous salvage raids, the wreck maintains an impressive structure, and supports a stunning forest of soft coral.
