Herbal löyly saunas in Japan — 22 facilities
Water in which herbs have been steeped is poured over the sauna stones, so the scent rises with the steam. 22 facilities across 17 prefectures in this guide run it, each verified on the facility's official site or an equally citable source.
10 can be used as a private or reserved room, 11 are shared only, and 1 do not publish which. The prefectures with the most are Gifu (3), Osaka (3), Nagano (2), Iwate (1) and Ibaraki (1).
4 of them publish the use of yomogi (Japanese mugwort). Note that yomogi-mushi — sitting on a stool with an opening while mugwort steam rises from below — is a different, single-person apparatus, and is not what this page lists.
Look up the herbs themselves in the RootHerb Index, and the styles and terms in the glossary.
