It seems that the sauna boom has become established. The Nifty Lifestyle Co., Ltd. (2024 Sauna Ranking List) has been announced, so let’s introduce it right away.

In the “Nifty Onsen Sauna Ranking 2024,” both the nationwide rankings in the general and private categories, as well as the rankings by region (East Japan and West Japan), will be announced.
The voters for this ranking are users of “Nifty Onsen,” where bath lovers gather. This ranking is different from the serious “Sauna Rankings” created by sauna experts, so it is well suited for those who want to enjoy saunas in the future.
