The Hiburi-class escort ship (日振型海防艦,, Hiburi-gata Kaibōkan) was a design development from the Mikura-class escort ships of the Imperial Japanese Navy (IJN), serving during and after World War II.^[2]

^ The vessel on the photograph has been identified as two different vessels.
First option: Daitō in August 1944, by Ships of the World special issue Vol.45, Escort Vessels of the Imperial Japanese Navy.
Second option: Shōnan in July 1944, by the Yamato Museum.
^ The 11 vessels described in this article are classified to the Ukuru class in many books, because the Hiburi class closely resembles the Ukuru class. The IJN's official documents, however, call them the Mikura class.
