Toyoshimaen Niwa no Yu is a garden hot spring facility associated with the former Toshimaen amusement park site in Nerima Ward, Tokyo, an urban spa that brought the hot spring bathing experience to a densely populated residential ward of the metropolitan capital in the traditional form of a garden-style bathhouse. The Toshimaen amusement park, which operated for nearly a century before closing in 2020 to be partially redeveloped as the Harry Potter theme park Studio Tour Tokyo, was one of the most beloved recreational spaces in the Tokyo metropolitan area, and the Niwa no Yu garden bathing facility provided a quieter alternative to the amusement attractions for visitors seeking relaxation in a garden setting with thermal water amenities. The facility exemplifies the Japanese tradition of bringing spa culture into the urban environment, making the restorative benefits of hot spring bathing accessible to residents of the capital who may not have the time or means to travel to traditional mountain or coastal onsen resorts.
