Nikkō-in, Buddhist temple in Yabu, Japan

Nikkō-in is a Buddhist temple nestled among mountains, built with traditional wooden structures that feature carved details and religious symbols throughout. The buildings display craftsmanship in their design, with details visible in the rooms and on the roofs.

According to temple tradition, the hermitage was founded by Nikkō Keijū during the reign of Emperor Bidatsu in the Asuka period. In 1485 it received a land donation from Yamana Masatoyo. Its halls, including Jōju-in, Yakushi-in and the Niō gate, were destroyed by fire in 1560 and 1570. Originally called Ishiwarayama Taishakuji Nikkō-in, it was renamed Myōkenzan Nikkō-in in July 1888.
