Raidori Onsen Raidori-so

Located about a 30-minute walk from the Murodo bus terminal and about a 15-minute walk from Mikurigaike Onsen is "Raidori Onsen Raidori-so ".

Raidorisawa Hutte

This hot spring is about a 40-minute walk from the Murodo bus terminal, about a 30-minute walk from Mikurigaike Onsen, and very close to Raidorisawa Campsite. Raidorisawa Hutte has separate indoor and outdoor baths for men and women. The indoor baths are small, with only six washing stations. There are no showers, so you use a hot water faucet and a water faucet to fill a washbasin with hot water of your preferred temperature in a retro style. There is no window in the indoor bath, so there is no view. The water is milky white, but unlike Mikurigaike Onsen and Raitoso, it has a slightly less sulfuric aroma.
The indoor and outdoor baths are not connected, so after leaving the indoor bath, get dressed before heading to the outdoor bath. The open-air baths are free-flowing hot-spring water with no added water, so the water is about 50 degrees Celsius and hot. Before entering the bath, you should pour out water from the faucet next to the bathtub and stir the water with a hand tub to set the temperature to your liking. It takes some effort to get into the bath, but you can enjoy the cool mountain air as well as the view of Tateyama.

Guests can enjoy draft beer and snacks after bathing, while day-trippers can purchase beer and chuhai from vending machines. You can drink on the benches outside the entrance of the hutte, so you can relax while enjoying the view of the Raitorisawa Campground.

Points to keep in mind when visiting Mikurigaike Onsen

atmospheric temperature

Mikurigaike Onsen is located at an elevation of 2,410 meters above sea level. Therefore, the temperature is lower than in the plains. To give you an idea of the temperature, if the temperature at Toyama Station is 20°C, the temperature around Mikurigaike Onsen is expected to be 6°C. And if the wind is strong, the temperature is even lower. Even if it is not cold at the time of departure, be sure to bring warm clothes such as a fleece or down jacket.
There is still snow in Tateyama during April and May, and in October and November, it begins to snow and on bad days it can even become a blizzard. For those who travel only to enjoy the hot springs, it is recommended to visit between June and September, when the weather is calmer.


Mountain weather is changeable. Even if it is only a 10-minute walk from the Murodo bus terminal to Mikurigaike Onsen, we recommend that you bring rain gear. Take a rain kappa instead of an umbrella. On windy days, the wind speed will be about 15 m/s, and your umbrella will break. Even a mountain parka that seems to be water repellent will get soaked after 10 minutes in the rain, so we recommend the use of rain wear.

personal effects

From the Murodo bus terminal to Mikurigaike Onsen, there are uneven cobblestones. There are also stairs in various places, making it difficult to walk with a carry-on bag. When going to Mikurigaike Onsen, be sure to bring a backpack or something that will free up both hands.
Also, the cobblestones are not well maintained. If you go there in heels, there is a possibility of twisting your foot. It is recommended that you wear sneakers that you are accustomed to walking in.


We introduced the attraction of "Mikurigaike Onsen ", which is located at the highest point in Japan. It is a mountain lodge, so it is different from a regular hot spring resort, but you can enjoy the food, atmosphere, and quiet time that only a mountain lodge can offer. Even if you are not a mountain climber, you can easily go for a walk between June and September, so why not enjoy the hot spring and the great nature of Tateyama?
