This is an injection-plastic ship model kit.
From the manufacturer:
Ordered in 1917 to the Sasebo Naval Arsenal and completed in April 1921 as the 4th vessel of the Harima-class cruisers, Kitakami was converted into a torpedo cruiser. She subsequently participated in the Battle of Midway as part of the Aleutian screening force. She was later used as a fast transport and made numerous sorties to Rabaul and other locations in the Solomon Islands and New Guinea. After taking severe damage in a torpedo attack by the submarine HMS Templar on 27 January 1944, she was converted to a Kaiten human torpedo carrier. She survived the war, and was used as a tender for repatriation vessels after the war.
Parts come molded in grey, with some clear parts, and decals included.
