Okinawa was an escort ship ("Kaibōkan") of the Imperial Japanese Navy during the Second World War. She belonged to the Ukuru class. The ship is most notable for its possible participation in the sinkings of two submarines.

Design and building

The Ukuru class escorts were very similar to the preceding Mikuru class. The main difference was a simplified hull form which enabled a shorter building time.Conway's All the World's Fighting Ships 1922-1946 Okinawa was built by the Nihon Kokan shipyard at Tsurumi. The building started on 10 December 1943 and some 8 months later the ship was completed. She was named after the island of Okinawa.

In service

During her career Okinawa spent most of the time escorting various ships in convoys. In November 1944 she participated in the Japanese Operation TA, the reinforcement of Leyte, by escorting troop transports. In December of the same year, Okinawa escorted the carrier Kaiyo.{{cite web |website=Nihon Kaigun Long Lancers |url=http://www.combinedfleet.com/taops1.htm |title=Operation TA}}
