The Kawasaki KH-4 was a four-seat general-purpose helicopter developed from the Model 47G-3B. Main changes incorporated an all-new cabin, a new instrument layout, a modified control system and larger fuel capacity. The engine retained was a 270hp Lycoming TVO-435-B1A or -D1A. An experimental variant of the KH-4 was the KHR-1 which was modified to test a three-blade rigid rotor system. This aircraft flew for the first time on 26 April, 1968.

At the beginning of the sixties, Kawasaki decided to develop a version of the three-seat Bell Model 47G-3, with a stretched cabin to make room for two rows of seats. The first KH-4 flew in August 1962 and received Japanese type approval on 9 November of that year. By the beginning of 1972, 193 of the Kawasaki KH-4 had been built, 19 of which were assigned to the Japanese Army, 23 to the Thai armed forces, four to the South Korean armed forces and one to the Philippines.
