The United States government has delivered the first Bell Boeing V-22 Osprey to Camp Kisarazu on July 10. The Japan Ground Self Defence Force (JGSDF) became the first operator of the V-22 outside of the U.S. military.

V-22 was already in use in Japan but US was the operator.

The V-22 can conduct multiple missions which are not possible with traditional rotorcraft or fixed-wing aircraft alone. The marine version resists corrosion and reduces the cost of long-term sustainability. The Japanese V-22 has a unique configuration with a Japanese-specific communication system.
