In 1942, Japan had begun development of new tanks to deploy onto the battlefield. However, these new tanks would take considerable time to produce, and Japan needed a quicker solution. As a result, the Chi-Nu would undergo many design changes. All of these changes had the single goal of mounting the Type 5 75mm cannon on a chassis that was easily mass-produced and which would require little or no change of existing production capability. The Type 3 Chi-Nu was designed with a Type 3 75mm tank cannon, derived from the dated Type 90 field artillery. Japan installed a prototype turret from the Chi-To onto the chassis of the Chi-Nu for testing purposes, labeling it the Chi-Nu Kai, with the tank performing a series of tasks at the Iyo Lake shooting grounds in Japan. The prototype proved successful in these trials and was accepted for use. The Chi-Nu turret was also re-designed for the Type 5 75mm gun, and this variant would become the Chi-Nu II.
