The Type 2 Ke-To Light Tank (????? ??, Nishiki keisensha Ke-To?) was developed by the Imperial Japanese Army during World War II as an improvement on the existing Type 98 Ke-Ni, which itself was built to replace the aging Type 95 Ha-Go. The designation ?Ke? represented ?light?, and ?To? represented the number seven.Shortcomings of the Type 98 design had been evident to both field troops and the Imperial Japanese Army General Staff since the start of the Pacific War. Although the older design had been able to hold its own in the Second Sino-Japanese War in support of infantry operations against the poorly armed National Revolutionary Army of the Republic of China (which lacked tanks or anti-tank weapons) it was a poor match for more heavily armed and armored Allied tanks such as the M4 Sherman.
