This class was planned to replace the earlier Isuzu-class and possess both ASW capability as the successor of the Chikugo-class and ASuW capability as the successor of the Yubari-class, but there are many enhancements as follows:
- Introduction of stealth technology.
- This class is the first combatant ship of the JMSDF with stealth technology. Their superstructure has traditional vertical surfaces, but their hulls are angled to reduce their radar cross section.
- Enhanced electronics.
- This is the first destroyer escort class with the Naval Tactical Data System and OYQ-7 combat direction system. It is also the first destroyer escort class which has ECM capability with the OLT-3 jammer.
- Modified weapon systems.
- The Short Range Air Defense system comprises the OPS-14 air-search radar, the OPS-28 surface search and target acquisition radar, one Otobreda 76 mm rapid-firing gun controlled by the FCS-2 fire-control system and Phalanx CIWS. The OPS-14 is the Japanese equivalent of the American AN/SPS-49 radar, and the OPS-28 is the equivalent of the American TAS Mk.23. Phalanx CIWS has given the ships an improved self-defence capability against anti-ship missiles. Mk.31 RAM GMWS Point Defense Missile System was planned, but it is not installed yet.
- The ASW system comprises an OQS-8 hull-sonar (Japanese equivalent of the American DE-1167), ASROC anti-submarine rocket from the Type 74 octuple launcher (Japanese license-built version of the American Mark 16 GMLS) and lightweight ASW torpedoes from two HOS-301 triple 324 mm (12.8 in) torpedo tubes. A Tactical Towed-Array Sonar System was planned but it is not installed yet.
The JMSDF intended to build eleven ships of this class, but finally, only six were built because Hatsuyuki-class destroyers started deploying in distinct forces. All six vessels of the class are named after World War II cruisers.
