After the construction of the Tenryū-class cruisers, the drawbacks of the small cruiser concept became apparent. At the end of 1917, plans for an additional six Tenryū-class vessels, plus three new-design 7,200 ton-class scout cruisers were shelved, in place of an intermediate 5,500 ton-class vessel which could be used as both a long-range, high speed reconnaissance ship, and also as a command vessel for destroyer or submarine flotillas. Kitakami was the third in a series of five vessels in this class which were built from 1918-1921.[1]
The Kuma-class vessels were essentially enlarged versions of the Tenryū-class cruisers, with greater speed, range, and weaponry.[1] With improvements in geared-turbine engine technology, the Kuma-class vessels were capable of the high speed of 36 knots (67 km/h), and a range of 9,000 nmi (17,000 km) at 10 kn (12 mph; 19 km/h).[1]
The number of 14 cm/50 3rd Year Type naval guns was increased from four on the Tenryū class to seven on Kitakami: two forward, one on each side of the superstructure and three aft, which meant that only six guns could be brought to bear on a broadside. The torpedo launchers were also increased to four double launchers: however, the Kuma class remained highly deficient in anti-aircraft protection, with only two 8 cm/40 3rd Year Type naval guns and two machine guns.[2]
On 25 August 1941, Kitakami returned to Sasebo for conversion to a "torpedo cruiser" with ten quadruple torpedo tube mounts for the 61 cm (24 in) Type 93 “Long Lance” torpedo, in line with Imperial Japanese Navy plans to create a special "Night Battle Force" of torpedo-cruisers. Modification was completed by 30 September 1941, and Kitakami was assigned to the Japanese First Fleet, CruDiv 9.[4]
From January to May 1942, Kitakami was assigned largely to training duties around the Japanese home islands. At the time of the Battle of Midway on 29 May 1942, Kitakami and her sister shipŌi were part of the Aleutian Screening Force, and returned safely to Japan on 17 June 1942.[4]
CruDiv 9 was disbanded on 21 November 1942, and Kitakami was assigned directly to the Combined Fleet. In November, Kitakami transported troops from Manila to Rabaul, New Britain, and returned to Sasebo by the end of the year.[4]
On 15 March 1943, Kitakami was reassigned to CruDiv 16 of the Southwest Area Fleet as a guard ship based out of Surabaya. She escorted three troop convoys from Surabaya to Kaimana, New Guinea during April and May.[4]
On 23 June 1943, while at Makassar, Kitakami, Ōi, Kinu and Kuma were bombed by ConsolidatedB-24 Liberators of the 5th Air Force's 319th Bomb Squadron. None of the cruisers were hit, but some sustained slight damage from near-misses.[4]
In late January 1944, Kitakami escorted another convoy to Port Blair. On its return voyage while transiting Malacca Strait, southwest of Penang, Malaya, on 27 January 1944, the Kitakami was hit aft by two torpedoes fired by the submarine HMS Templar. Kinu took Kitakami in tow to Angsa Bay, Malaya for emergency repairs, followed by extensive repairs at the No. 101 Repair Facility at Seletar Naval Base, Singapore in February. Repairs were not completed until 21 June 1944. However, after departing Singapore to escort the tanker Kyokuto maru, Kitakami began to take on water and had to put into Cavite Navy Yard in the Philippines from 12 July 1944 to 26 July 1944. Despite the additional repairs, Kitakami still took on water on her return voyage to Sasebo.
As a Kaiten carrier

From 14 August 1944 Kitakami was repaired and modified at Sasebo Naval Arsenal into a Kaiten human torpedo carrier with a capacity for eight Kaiten. A 20-ton crane, formerly from the seaplane carrierChitose, was fitted to raise and lower the Kaiten into the water. Her stern was remodeled into an overhanging ramp configuration and the aft turbines were removed as well, and the space used to hold spare parts and repair equipment. The removal of these turbines reduced Kitakami's top speed from 36 to 23 knots (67 to 43 km/h). All of Kitakami's remaining armaments were removed and replaced by two Type 89 127-mm AA guns and 67 Type 96 25-mm (twelve triple-mount and 31 single-mount) AA guns, two Type 13 air-search and one Type 22 surface-search radars. Two depth charge launching rails were installed at the stern and two depth charge throwers were also installed.[1] The refit was completed on 20 January 1945, and Kitakami was reassigned directly to the Combined Fleet.
In July 1945, an additional twenty seven single mount Type 96 25-mm AA guns were fitted to Kitakami. However, on 24 July 1945 about 200 aircraft Task Force 38's Essex, Ticonderoga, Randolph, Hancock, Monterey and Bataan again attacked the Kure area. Kitakami was damaged by strafing and thirty-two crewmen were killed.[4]
Post-war
After the surrender of Japan on 2 September 1945, Kitakami was moved to Kagoshima and assigned to the Repatriation Service. She was used as a repair tender for ships on repatriation duties.[1]
Kitakami was removed from the navy list on 30 November 1945,[3] and scrapped from 10 August 1946 – 31 March 1947.
