 It was the first class to use combined gas or gas (COGOG) propulsion system in the JMSDF.The all-gas-turbine propulsion system is composed of two Kawasaki-Rolls-Royce Tyne RM1C gas turbines for cruising and two Kawasaki-Rolls-Royce Olympus TM3B gas turbines for high speed operation.This combination and mounting method of these engines are similar to the Type 21 frigates of the British Royal Navy, so it was not possible to adopt an alternating engine room arrangement like a conventional JMSDF destroyer, the lack of redundancy was pointed out.
