It's a traditional Japanese house with different rooms available to be chosen. The room is equipped with a lot of items including pajamas, bathing suits, different types of towels, different types of snacks and drinks available for free, and even hair curler. The bathroom has a wooden bathtub which is very nice and offers the experience of a private onsen. The bed is extremely comfortable.
The only downside seems to be the windows. They use the traditional Japanese divider to block the sunlight without any curtain. So I was awakened by the sunrise at 5:30am or so every morning.
