We present a historical survey of accelerator projects evolved at KEK since its foundation as the National Laboratory for High Energy Physics in 1971. Also included is a brief description of the high energy accelerator programs in Japan prior to the birth of KEK, and a short account of Shigeki Suwa and Tetsuji Nishikawa, who played crucial roles in the birth and development of KEK.
