Hongō Water Supply Station Park, Urban park with water supply facilities in Hongō, Tokyo, Japan.
Hongō Water Supply Station Park is an urban park built on the former grounds of a water utility facility in Tokyo's Hongō district. It combines Japanese and Western garden designs with walking paths and seating areas spread throughout the site.
The water supply facility that emerged in the 1800s as crucial infrastructure for Tokyo's growth was transformed into a public park in 1976. This conversion allowed the community to gain new public space within a densely built area.
The garden is split in two: a Japanese garden on the south side, modelled on the Musashino coppices, where a stone channel of the Kanda aqueduct main line has been rebuilt, and a French-style garden on the north side with a pergola, a globe and a rose bed of 52 varieties and 300 plants, among them Knock Out and Golden Border.
Three nearby stations offer access: Ochanomizu, Suidobashi, and Hongō San-chōme are each about seven minutes walk away. The park's pathways are well-maintained and easy to navigate, making it simple to explore the different garden sections at your own pace.
The park covers 7,800 square metres above a distribution reservoir completed in 1974, which expanded a waterworks built by Tokyo's water bureau in 1892. The reservoir still operates beneath the lawns and paths, so the garden sits directly on working water infrastructure rather than on ordinary ground.
