Questions

Do the rooms at Mizunoto have hot-spring baths?

No. Suika-wing rooms have their own bath, a hinoki open-air bath in the Japanese-Western rooms and a semi-open-air bath in the Western rooms, but the water is not hot-spring water. The hot-spring water is in the large baths and the three private baths.

Is it Mizunoto or Mizunooto?

Both spellings are the same ryokan. The name is mizu no oto, "the sound of water", and the ryokan writes it Mizunoto in English.

Can guests with tattoos bathe at Mizunoto?

Not in the large baths, whatever the size of the tattoo. The three private open-air baths are free and open to guests with tattoos, as are the baths in the rooms.

How does dinner work at Mizunoto?

Dinner is a kaiseki course in the restaurant, at 17:30 or 20:00. You choose the course and the sitting at check-in, first come, and there are no private dining rooms.

Can Mizunoto cater for food allergies?

Yes. With two days' notice the ryokan serves a low-allergen menu without the 28 listed allergens. Buffet dishes label only the eight main allergens.
