Kōshō-ji (Uji)

Kōshō-ji is a Buddhist temple located in Uji, Kyoto Prefecture, Japan. It belongs to the Ōbaku school of Zen Buddhism, one of the three major Zen schools in Japan (along with Rinzai and Sōtō). Kōshō-ji is considered the birthplace of Ōbaku Zen in Japan, as it was originally founded by Ingen Ryūki, the founder of the Ōbaku school.

Originally established in Kyoto in 1643, the temple was moved to its current location in Uji in 1661, several years after Ingen Ryūki's death. The move was initiated by his successor, Mokuan Shōtō. The architecture of Kōshō-ji is notable for its distinctive Chinese-influenced style, reflecting the Ōbaku school's close ties to Ming Dynasty China. This influence is evident in its layout, building designs, and decorative elements.

Key features of Kōshō-ji include the somon (main gate), the sanmon (second gate), the butsuden (Buddha hall), and the hattō (lecture hall). The temple complex also includes smaller halls, gardens, and other structures. Kōshō-ji is a significant historical and cultural site, offering insights into the transmission and development of Zen Buddhism in Japan, particularly the unique character of the Ōbaku school. It is a designated Important Cultural Property of Japan.
