Tokyo has 1,663 public drinking fountains on the map, including 44 refill-friendly points for your water bottle. On the comfort side, 2,908 public toilets are mapped, 752 of them free and 769 wheelchair-accessible. The map also lists 349 public showers — handy after a run, a ride or the beach.
The map combines official open data with OpenStreetMap, then gets better every week thanks to its users: report a broken fountain in two taps, or suggest a missing one with a long press on the map. That's what makes H2Où the most up-to-date map of the city.
Most outdoor fountains are switched off during freezing months. The map flags indoor points and those that stay on year-round.
