About Keage Water Purification Plant

The Keage Water Purification Plant takes water from the Lake Biwa Canal and supplies the city, and is known as Japan's first rapid-filtration water plant. It is one of the canal facilities that have supported Kyoto's modernisation since the Meiji era.

The grounds are planted with countless azaleas, and public openings have been held to coincide with their peak. Slopes covered in red, white and pink blossoms are a sight many look forward to every year.

Being on a hilltop, the plant enjoys wide views of green Higashiyama and the city. Open days are announced each year; in 2026 they were April 25, 26 and 29. Facility tours require advance reservations (with a lottery if oversubscribed). Check Kyoto City Waterworks Bureau information before you go.
