About

Nara Ion House does one thing: kosoburo (酵素風呂), the enzyme bath where you lie buried up to your neck in fermented wood powder (ogakuzu, おがくず). The powder heats through fermentation and draws a deep sweat without any water involved. Reviewers often note that skin feels noticeably smoother afterward. After your session, you shower off in the washing area and can relax with tea in the lobby.

I went. Let me write my impressions now. It probably won't be a full review — I forgot to take photos. I'll post ones from the internet. Nara Ion House This was my first enzyme bath experience. First — the smell. Initially I thought, ugh, I have to get into this? Then you get used to it. The sensation — you literally feel like a potato. Then like a sweet potato grilling at the supermarket. Also a bit like a burial mound. But the heat is tolerable. The most interesting part is the feeling afterward. You don't wash it off right away — you're supposed to scrub with it first. But your skin afterward is unbelievably soft and the overall circulation is great too. And a sense of lightness. In the lobby there's delicious hatomugi tea. Downsides: it's hard to get to without a car, nothing runs there. And my personal downside — I like luxury, and this place is simple and old-fashioned. But it's clean and tidy, which is a plus. I'd go again. And their advertisement about becoming a new slim person — that's tempting!
