The history of Zensui-ji is uncertain, as the documentary evidence of its foundation has been lost. The temple's legend states that it was founded by Empress Genmei during the Wado era (708-715), and that the tempe was originally called "Wado-ji". During the early Heian period, Saichō came to the temple to pray for rain, and converted it to the Tendai sect. Later, when Emperor Kanmu fell ill, Saichō sent water from a spring at this temple, and the emperor made a miraculous recovery. The emperor bestowed the name of "Zensui-ji" on the temple in commemoration of this event. At its peak, the temple grew to have 26 subsidiary temples, which occupied both mountains adjacent to the main temple.
The temple is 3.9 kilometers, or approximately a one-hour walk, from Mikumo Station on the JR West Kusatsu Line.
The Main Hall (Hondō) of Zensui-ji was built in the Nanboku-chō period and was completed in either 1364 or 1366. It is in the irimoya-zukuri-style and is a seven by five bay building with a hinoki cypress bark shingled roof. The building was designated a National Treasure in 1954.[1]
The temple also has many statues which are National Important Cultural Properties:[2]
