Tokyo Toshima City
A day-use hot spring in Sugamo featuring amber-glowing natural hot spring water and a high-temperature sauna
"Tokyo Somei Onsen SAKURA" is a day-use hot spring facility in Toshima City, Tokyo. Beyond a narrow alley, a Japanese garden opens up, and natural hot spring water rises from deep underground in the birthplace of the Somei Yoshino cherry blossom. When it flows into the baths, it shimmers amber, and the mineral-rich water wraps around the skin, leaving warmth behind even after you get out. In the indoor cypress bath, you can sink into the lukewarm water, while in the open-air bath you can look up at the sky and feel the breeze. Work up a sweat in the heat of the stadium sauna, then regulate your breathing in the cold plunge bath and totonou space. With a restaurant overlooking greenery, relaxation services, and a resting area, you can spend the day in quiet comfort.

This natural hot spring rises from deep underground and shimmers amber as it flows into the tubs. The saline water gently wraps the skin and leaves warmth and moisture behind even after bathing. In the indoor cypress bath, you can slowly sink into the lukewarm water and surrender yourself to the quiet as both body and mind unwind. Outside, you can soak in the steaming amber water while looking up at the open sky, and enjoy a sense of a hidden hot spring even while staying in the city in an outdoor bath lined with stone and bamboo.

As its name suggests, the stadium sauna features tiered seating in a wood-lined room. The high heat penetrates deep into the core of your body, and you can work up a sweat at your own pace by choosing where to sit. Dark wooden walls and gentle lighting create a calm atmosphere, and the time spent facing the heat until sweat quietly rises helps you leave the noise of the city behind.

This cold plunge bath is set in a dim stone-tiled room, where water falling from the spout creates quiet ripples. The cold water that envelops your overheated skin gently tightens the body. In the adjacent totonou space, you can breathe deeply while feeling the outdoor air, and the back-and-forth between cold water and breeze naturally deepens your breathing.
