“The sauna was very spacious and the outside chilling area as well. You can throw water onto the sauna stove and its a proper Harvia stove. As a Finnish person i can highly recommend the place even though the prices were a bit steep in my opinion.”
“Beautiful, exclusive sauna. Make sure you book online. Very relaxing experience. Needed some signage outside but I located it easy enough.”
“This sauna is located in the building that houses architect Tanijiri Makoto's architectural firm. Apparently, he designed and manages it, too. This sauna is famous, even in the Sauna Michelin Guide, but because it's reservation-only, it's rarely crowded, making for a truly luxurious experience. The day I went, it was a cold night, so it was snowing even in Hiroshima, and the cold bath felt almost like a waterfall. I couldn't stay in the tub, so I poured water over my head with a bucket and shivered. On a warmer day, bathing in the open air would probably be nice, but it was just too cold. The cold bath was so cold that it felt like it was below freezing. In a way, it was a valuable experience. As mentioned in reviews, the area in front of the cold bath is extremely slippery when you pour water on it, so be careful. I almost fell over myself. The building itself is an old building that has been roughly renovated, leaving it as it is, which is very exciting for architecture lovers. You climb up a mysterious, abandoned staircase, making you wonder if there's really a sauna in a place like this, but the atmosphere is also exciting. I like the hideaway-like atmosphere. I wasn't sure if the finish on the walls of the stairwell was the same as it was back then, but it was really nice. I was curious about how it was constructed. The exterior of the building is painted red rust, which gives it a nice atmosphere. All reservations are made online, so once you get used to it, it's easy to make a reservation, and it's great because you can just go in without meeting anyone. The sauna is so amazing that there's no need to explain it. It's the best”
