Yamashiro

Yamashiro Province (山城国, Yamashiro-no-kuni) was an ancient province of Japan located in the Kinai region, corresponding roughly to the southern part of present-day Kyoto Prefecture. The name means "mountain castle" or "mountain province," a reflection of the mountainous terrain that characterizes the area, including the hills surrounding Kyoto.

From the 8th century, Yamashiro contained Heian-kyō (present-day Kyoto), the imperial capital established in 794. As the seat of government and culture for much of early Japanese history, the province played a central role in the political and artistic life of the nation. It continued to be an important regional hub through subsequent periods under various rulers. The province is known for its historic religious sites, including Enryaku-ji on Mount Hiei, a major Tendai Buddhist center, as well as numerous temples and shrines that contributed to Japan’s religious and cultural heritage.

Administratively, Yamashiro existed as a province until the Meiji era reforms that reorganized Japan’s territorial structure. In 1871, with the abolition of the han system, Yamashiro was merged into Kyoto Prefecture. Today, the historic area forms part of central and southern Kyoto, encompassing portions of modern Kyoto City and surrounding municipalities. The name Yamashiro endures in historical writing and local geography, reflecting the region’s medieval and early modern significance within the Kyoto region.
