Construction

She was built in 1937 under the 3rd Naval Armaments Supplement Programme, in preparation for the anticipated war with the United States. She was intended to supplement the Combined Fleet's existing food supply ship Mamiya. Her design was similar to that of Mamiya, but she was smaller. Her warehouse was able to supply 25,000 men over two weeks. A sister ship, Kusumi, was planned in 1942 under the Modified 5th Naval Armaments Supplement Programme, but construction was cancelled after the start of the Solomon Islands campaign.
