Notes:  The MOGAMI class were a part of the 1931 Supplementary Program, designed as light cruisers (although they were larger than most foreign heavy cruisers).  During trials, both MOGAMI and MIKUMA showed welding defects in their hulls, questionable stability, and distortions which prevented the turrets from being trained properly.  Both were taken in for refits in 1936-1938.  Additional strengthening of the hull and armor brought their displacement to 11,200 tons, but reduced their top speed from 37 to 35.9 knots.  Also, changes were made to their anti-aircraft armaments.  These modifications were deemed successful, and  KUMANO and SUZUYA were completed to these specifications.  In 1939-40, the class was "converted" to "true" heavy cruisers at Kure Navy Yard with twin 8" turrets replacing the triple 6.1" turrets, and more armor added, bringing their displacement to 12,400 tons and slightly reducing their top speed.

KUMANO was commissioned into the 7th Cruiser Division in October, 1937, where she served with her three sister ships.  Upon the beginning of hostilities in 1941, KUMANO took part in many operations.  In early June, 1942, CruDiv 7 was present at the Battle of Midway but KUMANO saw no significant action.  In early April, 1943, KUMANO was drydocked at Kure.  Her 13mm AA guns were removed and replaced by six 25mm AA guns in triple mounts, bringing their total to 20 barrels.  A Type 21 air search radar was fitted at the same time.  On 15 April, KUMANO returned to service.  Off Kolombangara on 18 July 1943, KUMANO suffered a near-miss from an aircraft bomb; some of her aft hull plates were damaged and she needed repairs.  Following two sets of emergency repairs, KUMANO arrived at Kure on 3 September 1943 for complete repairs, which took two months.  In late March, 1944, KUMANO received eight more 25mm AA guns (in single mounts).  In June, 1944, KUMANO took part in the Battle of the Philippines Sea.  Then in October, 1944, KUMANO took part in the Battle of the Leyte Gulf in "Operation Sho-Go" ("Victory").  On 25 October, Admiral Kurita's force attacked a group of American escort carriers and destroyers in the Battle off Samar.  During the battle, KUMANO was hit by a torpedo from the American destroyer JOHNSTON (DD-587); the hit tore off a portion of KUMANO's bow, reducing her top speed to 15 knots.  KUMANO was ordered to retire towards the San Bernardino Strait; while on her way, she was attacked by American torpedo bombers, which scored a near-miss.  The next day, KUMANO was again attacked by aircraft; this time, from the HANCOCK (CV-19).  Three 500-lb. bomb hits were scored by the attackers, further damaging KUMANO.  Following emergency repairs, first at Coron then at Manila, KUMANO was ordered to Formosa.  On 6 November 1944, off Cape Bolinao, Luzon, KUMANO was hit by two torpedoes fired by a "wolfpack" of four American submarines.  KUMANO's repaired bow was blown off, while the second hit blew a hole in her starboard side, causing an 11 list.  KUMANO was taken in tow by the DORYO MARU and was taken to Santa Cruz harbor.  On 28 November 1944, while under repairs there, KUMANO was attacked by aircraft from American Task Force 38's TICONDEROGA (CV-14).  She was hit by five torpedoes and four 500-lb. bombs, causing KUMANO to capsize and sink.
