I have booked this small 8sqm compact room on Agoda for about Yen 10,000 per night. It is tiny but has everything you can possibly need. It is designed in such a way that even if you have a lot of luggage, there is ample space under the bed to store it.

The bathroom even has a bathtub and all amenities are provided including face wash. It’s pretty amazing. You literally don’t need to bring anything as this hotel has a public bath and hot spring in the basement with cleanser and moisturizer creams.

There is even a laundry, microwave and ice machine area, as well as a breakfast restaurant (at additional charge). Robes, slippers, and towels are provided.

An excellent stay.
