The Type 3 Ke-Ri light tank was an experimental Japanese design which matched the chassis of the standard Type 95 Ha-go light tank with a 57mm gun. Although a modified turret was developed, there was very little space once the bigger gun was installed. Only a small number of Type 3 Ke-Ri light tanks were produced.
