The
Type 97 Chi-Ha (九七式中戦車 チハ
Kyūnana-shiki chū-sensha Chi-ha?) was a
medium tank used by the
Imperial Japanese Army during the
Second Sino-Japanese War, the
Battles of Khalkhin Gol against the
Soviet Union, and the
Second World War. It was the most widely produced
Japanese medium tank of
World War II.

The 57 mm main gun, designed for
infantry support, was a carry over from the 1933
Type 89 medium tank. The
suspension was derived from the
Type 95 Ha-Go light tank, but used six road wheels instead of four.
[5]The 170 hp
Mitsubishi air cooled
diesel engine was a capable tank engine in 1938.

The Type 97's low silhouette and semicircular
radio antenna on the
turret distinguished the tank from its contemporaries. After 1941, the tank was less effective than most
Allied tank designs.
[6] In 1942, a new version of the Chi-Ha was produced with a larger three-man turret, and a high-velocity
Type 1 47 mm tank gun. It was designated the
Type 97-Kai or Type 97
Shinhoto Chi-Ha.
