Design:

The hull is an enlarged type of Hatsuyuki class, and the hull form is of the shelter deck style. Also, as the latter batch of the Hatsuyuki class, the upper structure is made of steel, but since it was incorporated into the design from the beginning, the adverse effect on the movement performance was solved.

The engine room was greatly renovated. Instead of the COGOG propulsion system of the Hatsuyuki class, this class has the COGAG propulsion system with four Kawasaki-Rolls-Royce Spey SM1A gas turbines. With these powerful engines, it was possible to run at 26 knots (48 km/h; 30 mph) by driving only two of the four engines, especially the benefits of tracking a submarine were great. And alternating arrangement was introduced to improve resistance and durability, as in the steam turbine driven destroyers.

Equipment:
The earlier batch was equipped the OYQ-6 combat direction system (CDS). This system employed one AN/UYK-20 computer as the same as OYQ-5 tactical data processing system of the Hatsuyuki class, but with expanded memories, it can exchange tactical data via Link-11, which the OYQ-5 does not support. Later, all OYQ-6 systems were upgraded to the OYQ-7, integrated with OYQ-101 ASW Direction System. All ships of this class were later retrofitted with the terminal for the MOF system, the key operational C4I system of the JMSDF which uses the Superbird SHF-SATCOM.

The surface-search radars were replaced by OPS-28. The air-search radars were updated to OPS-14C in the earlier batch, and in the latter batch, OPS-24 3D radars were introduced. This was a maritime version of the land-based J/FPS-3 early-warning radar, and first shipboard active electronically scanned array radar in the world. In the latter batch, electronic warfare support measures systems were also replaced by NOLR-8, completely newly developed with emphasis on anti-ship missile defense.

Its weapon system is basically the same as the Hatsuyuki class except for the minor change on its FCS. However, a new SH-60J was installed as a shipboard helicopter, so a large capacity data link device was installed. The hangar is enlarged in order to accommodate two helicopters, but only one helicopter is used operationally.
