JS Yūbari (DE-227) was a Yūbari-class destroyer escort of the Japanese Maritime Self-Defense Force.

[1][2] The Maritime Self-Defense Force has further developed the Coast Guard (PCE) plan, which was considered in the Third Defense Build-up Plan as an alternative to the conventional submarine chaser (PC), and JS Ishikari in the post-fourth defense plan in 1977.

[4] From the above background, the basic design is an advanced version of 52DE.

The central hull form has been followed and looks very similar, but the standard displacement has been increased by about 200 tons, the total length has been extended by 6 metres (20 ft), and the overall width and depth have also increased slightly.

The vessel was engaged in disaster relief due to the eruption of Mount Usu that occurred on 31 March 2000.
