The JMSDF operated a total of 64 P2V-7 (SP-2H) patrol aircraft from 1956 to 1981. The first 16 were transferred from the USN, the remainder either assembled or manufactured by Kawasaki in Japan. The final delivery was in 1965, three years after Lockheed had finished production. This example was one of those delivered in knocked-down component form

One of 35 transferred from the USN to the JMSDF in 1957 and phased out in the mid 1960s. It was ordered as USAAF 44-47556 but before completion on the production line it was transferred to the USN as BuAer 85125. Carried code 3MSS-24 when in use as instructional airframe at the 3rd MSDF Service School at Shimofusa AB from 1964 to 1974

A total of 83 P-2Js were delivered to the JMSDF between 1969 and 1979. Besides converting the Neptune to turboprop power, Kawasaki incorporated many of the advanced systems used in the Lockheed P-3 Orion. A 54-inch fuselage extension between the wing and cockpit accommodated improved electronics

The JMSDF started receiving this version of the EC135 customised to Japanese requirements in late 2009 as replacements for the OH-6 trainer fleet. So far 13 are in service with 211 KyoikuKok at Kanoya
