Also called Osaka Shipping, this appears to have been a renaming of Kotani Kisen, with the former fleet at the same address in 1970–71. By 2000 it was an operating company of Mitsui OSK Lines. Kotani Kaiun, formed in 1981, moved from operating-company to name-company status in the registers. Kotani Steamship, formed in 1988, operated a joint venture with Osaka Senpaku and was subsequently listed under Mitsui O.S.K.
Japan, Osaka.
