Ishimura is probably a very ancient village. When peace came to Japan following the feudal period, the tengu ancestors of the Ishimura Clan settled in Ishimura to teach Bushido. The clan resides in a large temple near the village where most of the townspeople live. While the village still experiences threats both inside and outside its walls, peace is more or less a constant and the Ishimura Clan remains (as Kai claims), "the best kept secret in Japan."
Ishimura "石村" means "stone village."
