Kawanishi N1K1 "REX" Late

In the late stages of World War II, the Kawanishi N1K1 "Rex" (Kyōfū) floatplane fighter was primarily used for defensive roles in Southeast Asia and in the Japanese home islands. 
 
Key locations and units for the "Rex" late in the war included:
Borneo (Balikpapan): The first operational unit formed here in early 1944 for air defense, claiming 29 Allied planes before disbanding in less than two months.
Indonesia: Units were based out of Ambon and the Aru Islands in the Moluccas.
Malaya: Units were stationed at Penang Island.
Japan (Home Islands): In 1945, they were used for homeland defense, specifically operating from Lake Biwa (northwest of Kyoto) by the Sasebo Air Corps and the Ōtsu Air Corps.
Okinawa: They were also utilized during the Battle of Okinawa.
