The ship is nominally the second in the class, but the first-of-class is still being completed at the Mitsubishi Heavy Industries shipyard in Nagasaki.
The 30DX class is intended to initially replace Japan’s six Abukuma-class frigates and eight Asagiri-class destroyers. Construction is distributed among several shipyards, and is expected to deliver two ships per year beginning in 2022.
19 NOV, the naming and launching ceremony for the frigate "KUMANO" was held at Tamano Works, Mitsui E&S Shipbuilding Co.,Ltd. She combines compactness and manpower saving.

The 30DX frigate design has an overall length of 130 meters, a beam of 16 meters, and displaces about 5,500 tonnes fully loaded, and is designed to reach a maximum speed of over 30 knots thanks to its propulsion pack of MAN diesel engines and a Rolls-Royce MT30 gas turbine.
