Toshimaen Niwa no Yu in Mukoyama, Nerima-ku, Tokyo, is an 'otherworldly escape in the city' surrounded by a 1,200 tsubo Japanese garden. The outdoor Finnish sauna in the garden features 600 kg of sauna stones and an automatic löyly system, promoting vigorous sweating with the scent of wood. The mist-type steam sauna is set at 45-50°C, gently warming the body with humid heat. For cooling, there is a deep cold plunge bath with a garden view, 140 cm deep, enhancing the 'totonou' experience quietly with the outdoor environment. The water is a natural hot spring rising from 1,445 meters underground, with both open-air and indoor baths offering views of the garden.
