I made a reservation for Friday night with breakfast included. I left Haneda in the evening, so I rented a car and headed there, but I thought I wouldn't be able to get food in time. I tried to buy something at a convenience store along the way, but instead of going to a convenience store, I ended up on a mountain road! I thought this was a bad idea, so I checked it on the map (although it should have been fine from the beginning...) and went back to the 7-Eleven near Isosaki Branch.When I arrived at the hotel after buying dinner, I didn't know where the parking lot was because it was my first time there (at first I thought it was going down the gravel slope on the left in the foreground, but it looked different so I just stuck my head in, but it was back up). When I called in front of the inn, they told me it was late at night, so they let me park in front of the entrance. I couldn't do it anymore. sorry. I was told the location of the parking lot in the morning and confirmed it. There was a large parking lot a little further ahead. I'll park here next time.The lunch box I bought was heated and brought to my room. Perhaps because it was run by the family, they were very kind and apologetic.Now, onto the main topic! The main topic is hot springs!The best! (There is no open-air bath)I love alkaline hot springs, so I'm always looking for them. I decided to stay here after reading the reviews. It was good. I got there at night, so after a while the night bathing time was coming to an end, so I took one bath at night. The first thing I do in the morning is from 7am after I wake up. I chose breakfast at 7:30, so I ate rice and then once. It's open until 9am, so check out once before checking out. I went there 4 times leisurely.If there was one thing I noticed about this bathing facility, it would be that the shower was too strong, as was mentioned in other reviews. There was no one else, so I used it once and it turned out like this! That's what I thought, so I put it out sideways, but if I put it out straight, hot water from the shower would enter the bathtub, so I thought I'd have to be careful when it was crowded with customers. Also, the side that grips the shower head doesn't grasp the head at all, so if you let it out forcefully, the water pressure will cause the shower to angle upwards, causing it to flop into the bathtub behind you. I think this grip is also a factor, so I thought it would be much better to simply change the part that fixes the shower head to a firmer grip.Hot water is goodBoth the building and the rooms are nice (the toilet in the room had a washlet).The breakfast was also delicious.The people at the hostel are also kind.Other than the shower head, it's perfect for me!Take a bath with happinessI had a relaxing time in the large room.Thank you very much.
