Mimatsukan (Omotenashi no Yado Mimatsukan) is a 21-room inn in Ikaho Onsen, Shibukawa, Gunma, about 3 minutes on foot from the Stone Steps. Its landlady writes that it is a small inn that wants guests to feel warmth. Before you book, three things matter: it does not accommodate food allergies; it takes many credit cards but no electronic money; and its rooftop open-air bath has no washing area, so you wash in the indoor bath first.

Honto check: Every rule and figure below is from Mimatsukan’s official Japanese site, the fixed notes on its official booking page, and the Shibukawa City page on bathing tax, read on October 20, 2026. We have not stayed there. The inn has no English pages. Deliberately not stated: the tattoo rule, vegetarian or halal options, a curfew, which rooms have their own bath, a shuttle, and bus times or fares, none of which the official pages give.

Which room types does Mimatsukan have?

The room page shows four types. All rooms have a toilet with a bidet seat, a fridge, TV, safe, yukata, towels and Wi-Fi; a bath is listed as “in some rooms,” without saying which.

The baths at Mimatsukan

What is the rooftop open-air bath like?

Ukigumo, on the top floor, has two baths, Akagi-no-yu and Haruna-no-yu, which switch between men and women (on some days they do not switch). It is open 15:00 to 9:30, with breaks at night and for cleaning. There is no washing area and no shampoo; it is for soaking only.

What about the indoor bath?

The indoor bath, Zaan, has a floor of Ryukyu tatami and the same 15:00 to 9:30 hours, with shampoo, conditioner, body soap and hair dryers. The water is a simple hot spring (metasilicic acid) from Ikaho’s Shirogane-no-yu source, clear and odorless. Ask the front desk how busy it is.

Is there a private bath?

Yes. The private open-air bath Komochi-no-yu costs 2,200 yen per group (tax included), from 15:30 to 22:00. Apply at the front desk on the day; you cannot pick a time, and to book ahead you phone the inn. Check the length of a session with the inn when you book.

Can I bathe with a tattoo?

The official pages do not mention tattoos. Ask the inn before you book; our tattoo and onsen guide explains what to ask.

Meals at Mimatsukan

What is dinner like?

Dinner is the Joshu Kakaa-zen, a set meal where you choose your main dish; the base is Joshu mochi pork shabu-shabu, and Joshu beef mains cost extra (beef and pork from 1,100 yen, beef shabu-shabu or sukiyaki 2,200 yen, tax included, per the dining page). Check the surcharge on your plan. Dinner is at 18:00, 18:30 or 19:00, chosen at check-in; breakfast is Japanese, at 8:00 or 8:30. Guests arriving after 19:00 may eat in a separate room.

Where are meals served?

Meals are in the dining hall, except in Kodama rooms, where up to 3 guests can eat in the room. If you want the dining hall there, write it in the booking notes. Extra dishes, such as Akagi chicken yakitori, are on the menu.

Can the inn handle allergies or a special diet?

No for allergies: the inn states that it does not accommodate food allergies. The official pages say nothing about vegetarian, vegan or halal meals.
