The 1Ks were designed as ore carriers, with strengthened hulls and long welldecks fore and aft of a central island. The design was standardized by the Ministry of Communications, with assistance from the Navy Ministry, early in 1942, and was based on uniform specifications adopted by several yards prior to the war. They were not significantly different from peacetime designs and were intended for economical use after the war.
