Despite the success of the Tenryū-class high speed light cruiser design, the Imperial Japanese Navy felt that they would be outgunned by the larger US Navy Omaha-class of light cruisers then under development. The Kuma-class was the successor to the Tenryū-class, based on a larger hull that could accommodate larger guns, and was intended for both high speed scouting missions, and destroyer or submarine flotilla command assignments.

With the development of the long range oxygen-propelled Type 93 "Long Lance" torpedoes in the 1930s, the Imperial Japanese Navy drafted plans to create a special "Night Battle Force" of torpedo-cruisers. The idea was based on Japan's success in the naval Battle of Port Arthur in the Russo-Japanese War. As the new Type 93 torpedoes had a range longer than that of contemporary battleships main guns, the concept was to have a high speed strike force attack an enemy fleet at night with a massive and overwhelming barrage of torpedoes. Major surface combatants would follow up at dawn to finish off the wounded enemy.

However, the rapid development of naval aviation and submarine warfare in the 1930s quickly made this plan obsolete. Although the Kuma-class cruisers were never to fulfill their original design objective, the design provided to be useful in combat operations ranging from the Aleutian Islands to the Indian Ocean.
