Frequently asked questions
Which herbal saunas in Japan can be booked as a private room?
34 of the 103 facilities in this guide can be used as a private or reserved room. The prefectures with the most are Tokyo (7), Osaka (4), Nagano (2). Use the "Private / shared" filter on the list to narrow it down. 16 facilities use a tent, entered one person at a time.
What is the difference between Thai herbal steam and yakuso steam?
Thai-style herbal steam simmers Thai herbs such as plai, kamin (turmeric) and takrai (lemongrass), and fills a tent or a small room with the steam; the room is usually kept at a low to middle temperature, around 40–50°C. Yakuso (medicinal-herb) steam is the style found at bathing facilities across Japan, and covers rooms such as the kanpo yakuso salt sauna, where mugwort and kanpo crude drugs are turned into steam, as well as mushiyu and ishiburo, stone chambers warmed by hot-spring heat and lined with herbs. The families of herbs used, and the origins of the facilities, are different.
Is yomogi-mushi the same thing as a herbal sauna?
Yomogi-mushi is a Korean-derived style in which you sit on a stool with an opening and mugwort steam rises from below; it is usually offered as a single-person apparatus. This guide covers rooms you enter with your whole body — sauna rooms, steam rooms and tents. Many facilities also offer yomogi-mushi alongside; where that is the case it is noted in the “Style” row on the facility page.
