押上温泉 大黒湯

Oshiage Onsen Daikokuyu, six minutes from Oshiage Station, is a sento founded in 1949 whose baths use a weakly alkaline natural hot spring, with the Skytree in view from its large open-air bath. Both sides have a 95 °C far-infrared sauna; one side adds a mugwort salt steam sauna at 50–60 °C, and the two bath halls swap daily. Second-floor decks with hammocks serve for cooling. Sauna ¥300–400 extra on ¥600 entry; open mid-afternoon to 10:00 next morning; closed Tuesdays; tattoos allowed.
