Oyamazaki-cho is a town in Otokuni-gun, Kyoto Prefecture. It is located on the border with Shimamoto-cho, Mishima-gun, Osaka Prefecture. It is the smallest town in area in Kyoto Prefecture. The town belonged to former Otokuni-no-kori (present-day Otokuni-gun), Yamashiro Province.
Yamazaki has been a focal point for transportation since ancient times because the confluence of the Katsura-gawa (Yodo-gawa River system), Uji-gawa as well as Kizu-gawa Rivers are located at the foot of the hillside stretching deep into the plain. The Battle of Yamazaki, in which Hideyoshi TOYOTOMI (called Hideyoshi HASHIBA at that time) defeated Mitsuhide AKECHI, was waged in Mt. Tenno in Oyamazaki-cho. The idiomatic phrase 'Tenno-zan wo mukaeru' (approach Tenno-zan), meaning 'to have a showdown,' originated from this historical event.
