A registered heritage inn of 8 rooms, known for wild fugu
Reviews: Rakuten Travel 4.49/5 (233) · Agoda 8.7/10 (10) · 243 in total
- A small, quiet inn on the Atsumi Peninsula
- Large bath and open-air bath; the large bath has run on hot-spring water since October 2022
- 4.49 across 233 reviews, the highest average of the five; breakfast 4.67, cleanliness 4.59
Why it made the five
- Main building and annex both Registered Tangible Cultural Properties.
- Wild torafugu and fresh seafood.
- Eight rooms, including a room for wheelchair users.
- About ¥29,000–32,000 per person on a weeknight and ¥32,000–51,000 on a Saturday with two meals.
Getting there: Paid shuttle (¥800 per person each way, booked in advance), about 25 minutes from Mikawa-Tahara station on the Toyohashi Railway Atsumi line — one pick-up, at 15:00 — or from the Irago port ferry terminal at 16:15. About 80 minutes by car from the Toyokawa interchange on the Tomei expressway; free parking.
Language and payment: Per Rakuten, several staff understand a little English. Visa, Mastercard, JCB, American Express and Diners Club are listed, though some plans cannot be paid by card. Wheelchair-friendly, with a barrier-free room for wheelchair users. The large and open-air baths are communal and nude, and no tattoo rule is published. A bathing tax of ¥150 per person is added.
-
Right for: An old building, Atsumi fish, and a small inn where it stays quiet.
-
Not for: Getting there without a car — it is a long way from Nagoya and Toyohashi, and the paid shuttle from Mikawa-Tahara runs once in the afternoon.
-
Worth knowing: The shuttle is paid and must be booked; the Mikawa-Tahara pick-up leaves once, at 15:00. Call if arriving after 18:00; last check-in 19:00, check-out 11:00. Cancellation charges start seven days before.

Know before you book
- Gamagori is on the JR Tokaido line east of Nagoya, and Ginpaso’s listing puts Nishiura about an hour from Nagoya. From JR Gamagori station, Hotel Takeshima and Kaze no Tani no Io both run free shuttles if you book ahead.
- Nishiura Onsen, on the small peninsula west of Gamagori, has three of the five — Hanakazashi, Ginpaso and Suehiro. Its station is Meitetsu Nishiura on the Meitetsu Gamagori line, and all three collect guests from there; from JR Gamagori it is about 30 minutes by bus.
- Irago and the Atsumi Peninsula are much further out. From Toyohashi, a Tokaido Shinkansen stop, the Toyohashi Railway Atsumi line runs to Mikawa-Tahara, where Kakujoro and Izutsuro run a paid, pre-booked shuttle of about 25 minutes. Irago port has a car ferry across the mouth of Ise Bay to Toba, so the peninsula pairs well with Ise-Shima.
- The Atsumi Peninsula is known for wild torafugu, tiger pufferfish, and Kakujoro builds its kitchen around it. Fugu must be prepared by a licensed chef in Japan, so eating it at a ryokan is the safe way to try it.
- Japanese shared baths are nude, and you wash at the taps before you get in. None of these inns publishes a tattoo rule. Ginpaso and Suehiro have a family bath you can use with your own party, and Kaze no Tani no Io has an open-air bath in every room.
- Prices here are per person with dinner and breakfast, for two sharing. Most of these inns add a bathing tax of ¥150 per adult on the spot, and two of the five — Hanakazashi and Kaze no Tani no Io — do not take young children.

- Reviews: the count and average on Rakuten Travel, as given in each hotel’s Trust row. Agoda’s reviews are shown under each hotel name for reference only and do not count towards the score
Conditions (all of them, not most of them)
- In Rakuten Travel’s Toyohashi, Toyokawa, Gamagori and Irago district of Aichi, with a hot spring
- At least 30 reviews on Rakuten Travel, averaging 4.0 or better
- The cheapest rate falls between ¥8,000 and ¥40,000 per person per night
- An open-air hot-spring bath — a shared one counts; a private or in-room open-air bath is a bonus

What we dropped
| Property | Verdict | Why |
|---|---|---|
| Irago Onsen Izutsuro | Runner-up (64/100) | 64/100, two points behind Kakujoro, the fifth pick. It does the same job — a listed building on the Atsumi Peninsula — but room, bath and dinner average 4.44 against Kakujoro’s 4.50, and since you eat at Kakujoro anyway, the guide keeps the original. |
| Miya Onsen Higaki Hotel | Runner-up (63/100) | 63/100, three points behind Kakujoro, the fifth pick. The midnight check-in and free JR pick-up are real advantages, but room, bath and dinner average 4.34 and reviews 4.39 across 1,513 — two stars each for quality and trust — and its baths offer nothing the Nishiura inns do not. |
| Gamagori Onsen Hotel Takeshima | Runner-up (62/100) | 62/100, four points behind Kakujoro, the fifth pick. It is the cheapest of the eight and the easiest to reach from the JR line, but room, bath and dinner average 4.08 and reviews 4.06 across 1,102 — one star each for quality and trust, the lowest here. |
| Irago Ocean Resort | Outside the theme | 4.36 across 3,935 reviews — the most in the district — and every room has an ocean view, but its cheapest listed rate falls below our ¥8,000 floor, so it belongs in a budget guide rather than this one. |
| Dormy Inn Express Toyohashi | Outside the theme | 4.57 across 1,059 reviews with a natural hot-spring bath, but it is a city hotel near Toyohashi station, its cheapest rate is below our ¥8,000 floor, and its listing shows no open-air bath. |
| Irago Onsen Minshuku Tawaraya | Outside the theme | A nine-room seafood guesthouse near the Irago ferry terminal, 4.09 across 51 reviews, but its listing shows a hot-spring large bath and no open-air bath. |
| 9 more inns | Below the floor | Fewer than 30 reviews, or an average below 4.0. |
Questions visitors ask
Which one would you book?
Himeyado Hanakazashi, which scored 72/100, the top score in this guide: a 17-room inn for adults at Nishiura with dinner rated 4.55, from about ¥18,000 per person with two meals on a weeknight. If you are bringing children, which Hanakazashi does not take, look at Nishiura Onsen Suehiro for its family bath and connecting rooms, or Ginpaso for a sea view from every room.
How do I get there from Nagoya without a car?
For Kaze no Tani no Io, take the JR Tokaido line to Gamagori and use the inn’s free shuttle from the south exit, booked by the day before. For the three Nishiura inns, take Meitetsu trains to Nishiura station and use the inn’s pick-up; Ginpaso is also about 30 minutes by bus from JR Gamagori. For Kakujoro on the Atsumi Peninsula, go to Toyohashi (JR or Shinkansen), change to the Toyohashi Railway Atsumi line for Mikawa-Tahara, and take the inn’s paid shuttle, which leaves once, at 15:00.
I’d rather not bathe with strangers. What are the options?
Kaze no Tani no Io has an open-air bath in all nine rooms and no shared bath at all. Ginpaso and Suehiro each have a family bath you can use with your own party; how to book it is not published, so ask at check-in. Hanakazashi and Kakujoro have only shared large and open-air baths, which are nude in the Japanese way. None of the five publishes a tattoo rule.
We are travelling with children. Which should we avoid?
Himeyado Hanakazashi takes no children from babies to the sixth grade of primary school, and Kaze no Tani no Io takes no one below junior-high age except babies aged 0–2 sharing your bed. For families, Nishiura Onsen Suehiro has connecting rooms (some, booked ahead), a family bath, and free stays for children aged one and under; Ginpaso has a family bath and is wheelchair-friendly, which helps with grandparents.
Do any of these have English-speaking staff?
Himeyado Hanakazashi and Irago Onsen Kakujoro each say several staff understand a little English. Ginpaso, Suehiro and Kaze no Tani no Io publish nothing about languages, so ask when you book. All five list the major international cards, but Kaze no Tani no Io’s plans are card-payment only and some of Kakujoro’s plans cannot be paid by card.
How much do these cost?
The table shows the cheapest price per person with dinner and breakfast, for two sharing, from Rakuten Travel’s availability search for Wednesdays and Saturdays between 4 November and 26 December 2026, checked on 27 October. Weeknights run from about ¥18,000 at Hanakazashi to about ¥50,000 at Kaze no Tani no Io; Suehiro had no weekday rooms in that window but is the cheapest of the five on a Saturday, from about ¥21,000. Most inns add a bathing tax of ¥150 per adult on the spot.
