The West Japanese destroyer RJS Harusame (DD-102) at sea on March 23rd, 2006.

The Murasame-class destroyers are a third-generation general purpose destroyer in service with the Republic of Japan Navy.

The Murasame-class was designed to replace the RoJN's smaller destroyers that were reaching block obsolescence, ensuring the fleet could maintain its strength while increasing its firepower. It was originally planned that 14 of these would be built, but this was reduced to nine when the Takanami-class (a modified variant of the Murasame) was designed and construction begun.

The Murasame-class destroyers' weapon systems include the Sea Dart Mk,II surface-to-air missile, Thunderbolt surface-to-air missile, VL-Orca ASW missile, the SSM-1B anti-ship missile, two 30mm Goalkeeper CIWS gun mounts, two torpedo mounts in a triple tube configuration and a 76mm/62-caliber rapid-fire naval gun.

With the exception of Kirisame, all ships of the class are named for World War II destroyers.
