Dedicated torpedo cruisers based on the Furutakas but with lighter main armament and with four triple 21" tubes per side plus six reloads. Two planned, Kitakami, Kiso. A half sister (Oi) will replace the torpedo tubes with space for four 20t radio-guided MTBs.

Screw it, armor is overated. Only 100t more expensive but adds better guns, better torpedoes, and a knot. An extra knot and a 2" belt was not worth the 800t.
