Nakanobo Zuien, Arima Onsen (2026): Adults Only, Tattoos

Guide·September 26, 2026·18 min read·Sourced & cross-checked

Nakanobo Zuien is a 47-room ryokan in Arima Onsen, the hot spring town in the hills behind Kobe, and it has both of Arima’s waters: the brown kinsen and the clear ginsen. Its rules are the kind that decide whether you can book at all: no one under 13 may stay, even at the adult rate; tattoos are not allowed in the large baths; there is no bathing-only entry; and cancellation charges begin seven to ten days out.

This page reads the ryokan’s own English and Japanese pages, FAQ and terms of stay, and says so where they disagree with each other. For where Arima sits relative to Kobe and Sannomiya, see our Kobe map.

Where the English and Japanese pages disagree, we say which is which. Deliberately not stated: room rates; the amount of the bathing tax, which the terms list without a figure; the contents of the day-use plans, which load on a booking page we could not read; and the shuttle timetable, which the site does not publish.

Why Nakanobo Zuien is adults only

Under 13 cannot stay, whatever you pay

The English page is titled adults only and says that children below the age of 13 are not permitted, and that the rule holds even if a full adult fare is paid. The Japanese page says the same. This is the single rule that rules the ryokan out for most families, and it is easy to miss on a booking site that simply shows two adults.

Where the ryokan sends families instead

The FAQ answers the question directly: families with children are asked to use the sister hotel in Arima, the Arima Grand Hotel. Because children cannot enter, the ryokan also has no nursing room, baby chair or changing table.

The one place children can go

The Japanese restaurant on site, Shunsai Inano, is open to non-guests and to children. It is not a private room. So a family staying elsewhere in Arima can still eat here, which is worth knowing if one of your party is staying and the others are not.

The baths at Nakanobo Zuien: kinsen, ginsen and tattoos

What kinsen and ginsen actually are

The ryokan publishes both analyses. Kinsen is an iron-bearing sodium chloride strong-salt spring, hot and brown, run through the baths with some recirculation but no water added and no heating. Ginsen is a simple, weakly radioactive cold spring, which is heated and has water added. The ryokan adds that the kinsen contains seven of the nine main components Japan’s environment ministry uses to define a therapeutic spring, and that only baths labeled kinsen or ginsen use spring water.

The large baths are kinsen only

The two large baths, Zuisen and Sousen, open 14:00 to 24:00 and 5:30 to 12:00, and the men’s and women’s sides swap overnight. Zuisen has an indoor bath with a mid-to-low temperature sauna and an outdoor bath facing the garden; Sousen has a mist sauna. The English page calls the second bath “Ten-sen”; the Japanese page calls it Sousen.

Tattoos: not in the large baths, try the private bath

The FAQ says guests with tattoos are asked not to bathe, and suggests booking the private bath. The English page puts it as “No tattoo allowed” under the large baths. The terms go further and list tattooed guests using the large baths among the rule breaches for which the ryokan may end a stay. Our tattoo and onsen guide explains why a private bath is the standard answer in Japan.

The two private baths

The family bath, Jusen, uses kinsen, costs 4,400 yen, runs 6:30 to 22:30 and must be reserved. Separately there is a free private outdoor bath with ginsen, which you lock from the inside, open 6:30 to 22:30. Bring your own towels to that one; the ryokan says so.

No bathing-only visits

The ryokan does not take visitors for bathing only. It does sell day-use plans, but the list sits on a booking page that did not load for us, so we cannot tell you what they include. Our guide to Japan’s onsen law explains how to read the spring analysis panel posted at every onsen.

Two penalties in the terms. Smoking in a non-smoking room is charged at 100,000 yen per room, and if a large bath has to be drained and cleaned after an accident the charge is 30,000 yen. The whole building, including the rooms and outdoor baths, has been non-smoking since June 3, 2022, except the smoking areas on the first and second floors, and that includes e-cigarettes.

Cancellation and check-in at the Arima ryokan

The cancellation clock depends on the night

For up to eight guests, the FAQ gives two starting points. On a weekday, 30 percent is charged from seven days before. On a Saturday or the night before a holiday, 20 percent starts ten days before and rises to 30 percent at seven. From there it is 50 percent two days before, 80 percent the day before and 100 percent on the day or for a no-show. Larger groups should ask.

Peak days start two weeks out

The terms add a separate table for peak days: December 29 to January 3, May 3 and 4, and August 11 to 16. On those dates, for up to eight people, it is 20 percent from 14 days, 30 percent from 10 days, 50 percent from 7 to 3 days, 80 percent two days and one day before, and 100 percent on the day. Cutting a stay short or reducing the number of guests is charged on the same table.

Check-in time, and the one page that disagrees

The FAQ, the English top page and the terms all say check-in 14:00, check-out 12:00. One English guide page says check-in is from 13:00. Take 14:00 as the rule and ask if you need the room earlier. Staying past noon is charged as a share of the room charge: 30 percent for up to three hours, 60 percent for up to six, and 100 percent beyond that. There is no curfew.

What counts as a no-show

If you have not arrived and have not called by 8 p.m., or two hours after the arrival time you gave, the ryokan may treat the booking as canceled. Call if your train from Osaka is running late.

Dinner, breakfast and the 19:30 cutoff

In your room or a private dining room, not both

Meals are served either in your room or in Arima Yusai, private dining rooms with chairs and tables on the second floor. The FAQ says the ryokan cannot serve dinner in your room and breakfast in the dining room; you choose one place for both. The English guide describes dinner as a kaiseki course of 8 to 13 dishes.

The last dinner start is 19:30

Dinner in your room or in private dining must start by 19:30. If you arrive later, dinner moves to the Inano restaurant between 19:30 and 20:30. The terms give breakfast as 7:30 to 9:00; one English page says 9:30. Western breakfast is available except over the New Year period, and breakfast can be switched to brunch at Inano on days it is open.

Allergies need three days

Tell the ryokan at booking or at least three days before. The English page warns that cookware and cooking oil are shared, so cross-contamination is possible. A vegetarian menu is listed for the Inano restaurant. Drinks other than Japanese tea cost extra; room service runs 7:30 to 23:00 and the bar’s last order is 22:30. If Kobe beef is part of your trip, our Kobe beef guide covers how to tell the real thing.

Getting to Nakanobo Zuien in Arima Onsen

The ryokan publishes approximate times and fares. From Sannomiya, about 35 minutes by train for 680 yen, or 30 minutes by JR express bus for 780 yen. From Osaka, about 1 hour 10 minutes by train for 1,090 yen, or an hour by JR express bus for 1,400 yen. From Kyoto, about 1 hour 40 minutes by train for 1,780 yen, or 1 hour 10 minutes by Hankyu bus for 1,850 yen. The ryokan notes times change with connections.

Money and small print at Nakanobo Zuien

What is added to the rate

The terms add a 15 percent service charge to the basic rate, then consumption tax and bathing tax. JCB, American Express, Diners, Visa and Mastercard are accepted, but some plans require prepayment or cash only. The ryokan may ask for a deposit of up to three nights by a set date, and foreign guests register a nationality and passport number.

Language, rooms and access

The English page lists six English-speaking staff. Rooms have yukata or samue, with pajamas on request, and a choice of five pillows. There are wheelchair-accessible rooms, but the ryokan notes a step at the washbasin and no wheelchair-accessible toilet. For how a stay like this differs from a hotel, see our ryokan guide.

Valuables, luggage and wearing the yukata outside

The front desk will hold valuables up to 800,000 yen; items you do not declare are covered only up to 100,000 yen, so hand in anything expensive. If you arrive before check-in you can leave your bags, and luggage sent ahead is kept only if you arrange it beforehand. Things left behind are kept for seven days and then handed to the police. The English guide says the yukata can be worn in your room, around the ryokan and on a short walk in the hot spring area, which in Arima is part of the point of staying.

Celebrations and special requests

For a birthday or anniversary the ryokan can prepare red-bean rice, festive chopsticks and table settings at dinner, but only for guests on a plan with dinner and breakfast who eat their kaiseki in the room or a banquet room. For guests who can only eat soft food, the FAQ asks you to say at booking what you cannot eat and how much, and the kitchen will adjust where it can.

Frequently asked questions

Can children stay at Nakanobo Zuien?
No. The ryokan does not accept anyone under 13, and its English page adds that the rule holds even if you pay the full adult rate. There is no nursing room, baby chair or changing table for that reason. The ryokan points families to its sister hotel in Arima, the Arima Grand Hotel. Children may still eat at the ground-floor restaurant, Inano, which is open to non-guests.
Can I use the baths at Nakanobo Zuien with a tattoo?
Not the large baths. The FAQ says guests with tattoos are asked not to use them, and the English page says no tattoos. The ryokan’s own suggestion is to book the private family bath instead, which costs 4,400 yen and is reserved in advance. There is also a free lockable private outdoor bath with the silver spring.
What are the check-in and check-out times?
Check-in is 14:00 and check-out is 12:00, according to the FAQ, the English top page and the terms of stay. One English guide page on the site says 13:00, so if an early room matters to you, confirm when you book. There is no curfew and the front desk is staffed all day.
What is the cancellation policy?
For up to eight guests, on weekdays 30 percent is charged from seven days before. For a Saturday or any night before a holiday, 20 percent starts ten days before and 30 percent seven days before. Then it is 50 percent two days before, 80 percent the day before and 100 percent on the day or for a no-show. Peak days over New Year, early May and mid-August start at 20 percent 14 days out.
Can I visit the onsen for the day without staying?
Not for bathing only. The ryokan says it does not take bathing-only visitors. It does sell day-use plans, but the list loads in a booking page we could not read, so we cannot say what they include.
What is the difference between kinsen and ginsen?
Kinsen, the gold spring, is an iron-bearing sodium chloride water that runs brown; the ryokan uses it without adding water or heating. Ginsen, the silver spring, is a clear, weakly radioactive cold spring that is heated and has water added. At Nakanobo Zuien the large baths are kinsen only; ginsen is in the free private outdoor bath.
What time is dinner, and can I eat in my room?
Dinner is served either in your room or in a private dining room with chairs on the second floor, and you cannot split dinner and breakfast between the two. The last dinner start is 19:30. If you arrive later, dinner is served at the Inano restaurant between 19:30 and 20:30.
What extra charges should I expect?
The terms add a 15 percent service charge to the basic rate, then consumption tax and bathing tax. Some plans are prepaid or cash only. Two penalties are written into the terms: 100,000 yen per room for smoking in a non-smoking room, and 30,000 yen if a large bath has to be drained and cleaned after an accident.

Bottom line (2026): Nakanobo Zuien is an Arima Onsen ryokan with kinsen and ginsen, and it is adults only: no one under 13, even at the adult rate. Tattoos are not allowed in the large baths; the ryokan suggests its 4,400 yen private bath. There is no bathing-only entry. Cancellation starts at 30 percent seven days out on weekdays, and dinner must start by 19:30. A 15 percent service charge is added.
