JS Sawakaze (DDG-170) was the third ship of the Tachikaze-class destroyers built for the Japan Maritime Self-Defense Force (JMSDF).

No helicopter facilities are provided, and the ASW armament is confined to ASROC missiles and Mk 46 torpedoes.

In order to save on construction costs the class adopted the propulsion plant and machinery of the Haruna-class destroyers.

On February 13, 2002, based on the Act on Special Measures Against Terrorism, dispatched to the Indian Ocean along with Haruna and the supply ship Tokiwa.

On June 25, 2010, she was decommissioned along with the escort ship Hatsuyuki to the Yokosuka District Chief, Sadayoshi Matsuoka, and retired.
