Japan Defense Tanks*
*
This formation holds the rarest of Japanese tanks, some of whom were only built in prototype and in very few numbers.  one can speculate that if the war had continued, more would have been built.  The Type 1 Chi-He saw combat, and perhaps the type 2 Ho-I, but all the rest were kept on the Japanese main islands and never saw the enemy before the war ended.*
*
Here are some production numbers according to several sources:*
*
Type 1 Chi-He = 170-587 *
Type 2 Ho-I   = 30 *
Type 3 Chi-Nu = 60-100 (another 100 in production) *
Type 4 Chi-To = 6 *
Type 5 Chi-Ri = 1 *
