Source of Water in Sapporo, Japan

Sapporo’s tap water primarily comes from surface water sources, including the Toyohira and Sosei Rivers. These rivers provide abundant, clean water.

The water is collected in reservoirs and dams, such as the Chubetsu Dam, which store and supply water throughout the year, ensuring consistent availability.

Groundwater also supplements surface water, especially during dry seasons, but surface water remains the main source for Sapporo’s municipal water supply.

Sapporo Drinking Fountains

Public drinking fountains in Sapporo use treated tap water, which meets national safety standards, making the water itself safe to drink.

However, cleanliness and maintenance of fountains vary, so users should visually check for hygiene before use to avoid bacterial contamination on surfaces.

When in doubt, using personal water bottles filled from home tap water is advisable, ensuring safe hydration without relying solely on public fountains.
