The Yubari-class destroyer escort (or frigate) of the Japanese Maritime Self-Defense Force is the successor of the Ishikari-class destroyer escort. Yubari was named after the experimental light cruiser of the 1920s-30s, which served in (and was lost during) World War II.

This class was the extended version of its predecessor, JDS Ishikari (DE-226). The displacement was slightly increased, and some improvements were introduced. But they were almost same and there were many points in common as follows:

Both ships of this class were deployed at the Ominato District Force (home-ported at Mutsu, Aomori). The Ominato District is the northernmost district of the JMSDF and forefront against the Russian Pacific Fleet. Originally it had been planned to build six of this class (1985 Mid-Term Defense Buildup Program). However it was decided that this class was too small to continue in production, so it was succeeded by the Abukuma-class with an entirely new design.
