かのせ温泉赤湯

Visited in June 2025 This day-trip hot spring also features a campground and lodge facilities. Head 5-6 kilometers from Route 49 toward the mountains. The building that appeared was a magnificent wooden lodge-style structure. I was surprised to find it in such a place! The entrance fee was a reasonable 500 yen. The interior has a completely different atmosphere once you step inside, and it's very pleasant. The staff were also very friendly. The hot spring is on the first floor, and the restaurant is on the second floor. The stairs to the second floor are also made entirely of wood, adding to the charm. The hot spring water flows freely from the source at 60 degrees. There are three bathtubs: two indoors and one open-air bath with a roof. The water is cloudy, perhaps due to its chemical composition. First, I went to the open-air bath. It wasn't very large, but it was a little hot. Next, the indoor bath. The baths further from the outlet were even hotter. I slowly let my body get used to the water before entering. Finally, there's the bathtub with the outlet. It's hot here! My legs are stinging. I slowly squat down, buttocks, stomach, chest... By this point, the heat is unbearable lol I endure it for a minute...and start to sweat lol When I get out, my whole body is bright red! The sweat doesn't go away for a while. But after a while, my body feels refreshed! I might get addicted lol. The hot bath is over 50 degrees. I've been to hot springs all over the place, but this might be a hidden gem that will leave a lasting impression. I'll definitely visit again. I'd also like to come here for camping or a barbecue. Thank you for your help!

Akayu Onsen, located at the Tsunogami Campground in Kanose, is surrounded by a log cabin-style building with a parking lot. There's also a restaurant, making it a great place to spend a long time. Open only during the winter months from December, the facility is also open for reservations for banquets. Due to the high source temperature, the indoor and outdoor baths, with windows open, are filled with 59°C spring water, 100% pure and undiluted. One side of the two separate indoor baths is particularly hot, offering a chance to gaze upon the masters. Of course, the water can be diluted, so even children enjoy it. It's perfect for a cold day. The sodium-calcium sulfate hot spring (neutral, hypotonic, high-temperature spring) is said to be effective for neuralgia, muscle pain, and joint pain. Reception opens at 10:00 and closes at 19:30 and 20:00. Closed on Tuesdays. Since the facility is located in the mountains, please be careful with your car's equipment, especially in winter.

I've experienced many hot springs, but the hot water in the indoor bath here was close to the hottest point I could bathe in! It seems to be a whopping 49 degrees, and sometimes even 50 degrees! I think it's best to get used to the low-temperature baths (which are still plenty hot, lol) before attempting this. This is a wonderful hot spring where you can really feel the energy of the earth. It's sure to be a great training experience, and it was a truly valuable experience that made me feel like I understood a little bit about Ishikawa Goemon's feelings. Just be careful not to accidentally get into the hot water.

The water is brown and slightly salty. The hottest bath is a whopping 50 degrees, thanks to the 59-degree hot spring water flowing through it! Is that a joke? Is there anyone who can bathe in it? The bath next to it is about 45 degrees. That's more than enough for a pro (lol). Only the open-air bath can be adjusted with water. Not the indoor bath. The water is rich in nutrients, and the bathing fee is relatively inexpensive. Free oshiruko (sweet red bean soup) and amazake (sweet rice drink) are served at the beginning of the year. It's for advanced bathers, but if you're in Niigata, be sure to check it out.

I visited on January 2nd to collect stamps for the stamp rally. I had heard that the baths were quite hot, so I went in with some preconceived notions. The open-air bath was just big enough to get in. You really couldn't stay in the indoor bath for long unless it was filled with water. Even after I got out, my body was so warm I didn't feel cold at all. Compared to the waters at other day-trip hot springs, it is much warmer. They were serving generous servings of oshiruko and amazake (sweet red bean paste) on the day I visited. I recommend it for cold days.
