Fuse Hot Spring

November 22, 2025, Evening Bath & Dinner I arrived around 5:45 PM. The parking lot near the entrance was full, so I parked one level lower. The bathing fee is 500 yen, but with the JAF discount, it's 450 yen. To receive the discount, please go directly to the reception desk instead of purchasing a ticket from the vending machine. There are free shoe lockers, 100-yen returnable lockers for valuables, free baskets for changing clothes, and conditioner-in-shampoo and body soap provided. I came to take a bath, but there was a dining room (with table seating) just before the bath entrance. I looked in and saw that there were only about three groups of customers, and since I was hungry, I decided to have dinner first. I purchased tickets for a handmade croquette set meal (750 yen) and ramen (700 yen) from the vending machine, handed them to the dining counter, and waited for a while. After about five minutes, my ramen was called first, and about three minutes later, my set meal was called and served. The ramen had thin, curly noodles and a sweet broth, and was perfectly edible. I seasoned one croquette with sauce and the other with salt, but I think salt would have been fine for both. I recommend the salt, which brings out the sweetness of the potatoes. With my stomach full, I headed to the bath, and there was a sign on the wall of the changing room that said the bath temperature was set at 40-42°C. There were quite a few customers, but it didn't feel crowded until I had to wait in line for the washing area or sauna. There was one indoor bath, and since it was night, it looked colorless and transparent, I couldn't smell it, and the water temperature on my own thermometer was 38°C! That's not 40°C! It felt quite lukewarm. There were about 15 washing areas with no partitions, and one shower booth. The sauna's thermometer read 96°C, which was pretty good, and the cold water bath was also cool and refreshing. There were two open-air baths, one circular and one rectangular, both at 40°C. The indoor bath was so lukewarm that it felt very warm. There were five chairs in the open-air area, so you could also enjoy an open-air bath. I alternated between the open-air bath, sauna, cold bath, and open-air bath, relaxing for an hour.

I visited at 12:30 on a weekday while traveling from Tateshina to Saitama. I put my shoes in the shoe locker and bought a bath ticket from the machine. There was also a 500 yen adult admission and an 1100 yen lunch set. The 5-star rating is based on value for money and does not reflect the facilities or management. Most of the visitors were elderly, with a few elderly people struggling to walk. The changing room was mainly equipped with baskets, with about 15 lockers with locks. There were also lockers for valuables, so they were used for different purposes. There was a large indoor bath, sauna, cold bath, and slightly heated outdoor bath. There were many washing areas considering the size of the bath, so it never got crowded. The quality of the spring water was unknown; it was colorless, odorless, and not slimy. It seemed to have a slight salt content, so I think it was a salt spring, but the details were unclear. For a bathing fee cheaper than Tokyo's public baths and such facilities, I couldn't complain. If you're in the area, please stop by.

It was night, but I stopped by for a quick break. It's 500 yen for adults and 250 yen for children (up to elementary school age). Super cheap! The baths were especially nice, especially the open-air bath. ♨️ The sky was so expansive, so I enjoyed a relaxing soak while gazing at the stars. 😊 The facility is quite spacious, with a dining area (with a wide selection of menu items) and a relaxing tatami-floored table space. It's a great place for both solo travelers and families (depending on the number of people, of course). Parking is scattered throughout the facility. Just park wherever you find one.

The facility was even more impressive than I expected. In addition to a large rest area, there is a dining room and private rooms (for a fee), so you can stay here and relax at your own pace. The water is colorless and transparent, but it is a natural hot spring, so it warms you up nicely and leaves you feeling refreshed after bathing. The basic facilities include an indoor bath, open-air bath, and sauna, and it is bright and clean. Anyone can use all of this hot spring facility for 500 yen, with no time limit. I envy those who live nearby and can go whenever they want.

I stopped by on my way back from hiking Mt. Tateshina. There's an open-air bath and sauna, and the hot spring price is an incredible 500 yen. I also had rice, and the pork cutlet was delicious. I'd like to try the ramen next time, as they apparently make it from dashi stock. I really liked it. I'll definitely go again.
