Ichikawa Bekkan Seikanso is a 24-room inn on a green hilltop in Ikaho Onsen, Gunma. The inn says its rooms look out over Mount Akagi and the Tanigawa range, with the Nikko mountains in the distance. Before you book, three things matter: its three private open-air baths are free and need no booking; dinner is served in private dining areas; and allergy requests must reach the inn by 7 days before your stay.
Three free private open-air baths at Seikanso
The inn’s own tagline is “views and three free private open-air baths.” The water is a simple hot spring the inn calls Shirogane no Yu, listed for fatigue recovery.
How do the private baths work?
There are three: Shirakaba and Mayumi, both open-air, and Futarishizuka, a semi-open-air bath of hinoki and hiba wood. They are free and not booked; use one whenever it is empty, for about 30 minutes a time. They run as private baths from 15:00 to 23:00, and are one flight of stairs down from the large baths.
What happens to them in the morning and in winter?
In the morning, until 9:30, Shirakaba becomes the men’s open-air bath and Mayumi the women’s. Futarishizuka is not used as a private bath in the morning, except as a perk for guests in the top-floor view rooms. In winter, the washing areas of the open-air baths cannot be used because the pipes freeze.
What about the large baths?
There are two large baths, Yamabuki and Hototogisu, and they swap between men and women at night. The official pages give their hours differently in different places, so check the times at check-in.
Can I bathe with a tattoo?
The official pages do not mention tattoos. The private baths are used by your own group, but ask the inn before you book. Our tattoo and onsen guide explains what to ask.

MOKUREN is the only room with its own bath, a semi-open-air tub filled from the same hot spring, and children cannot book it. For the Showa retro rooms, there is no elevator: you climb two floors from the front desk, and the inn says these rooms do not suit older guests or anyone with limited mobility. Rooms have a TV, fridge, safe, kettle, hair dryer, yukata, towels and toiletries.
Meals at Seikanso
Where and when is dinner served?
Dinner is a kaiseki meal in private dining areas, starting from 18:00; tell the inn if you will arrive late. One plan instead serves a dinner bento in your room. Breakfast runs at 7:30, 8:00 or 8:30, with Koshihikari rice from a farm in the Tone-Numata area.
What is the signature dish?
The inn’s specialty is a braised block of Waton mochibuta pork, a dish it says recreates the power food of the Sanada warriors linked to the Ikaho stone steps. It comes with some plans, or as an extra plate of 400 g for 3,800 yen. Other plans add Joshu beef sirloin or offer smaller portions.
Can the inn handle allergies or a special diet?
The FAQ says to raise allergies or religious food needs when you book, or up to 7 days before your stay. The booking page explains that the kitchen can only leave the ingredient out. It cannot handle wheat allergies, allergies to traces such as egg or dairy used as a binder, allergies to ingredients in common seasonings, or other cases where removing the food is hard.

Each plan’s price depends on the number of guests, so compare on the same headcount. A bathing tax applies in hot-spring towns; confirm the amount with the inn, and see our onsen bathing tax guide.
