Know before you book
- The rail gateway is Oboke station on the JR Dosan line, where the Nanpu limited express between Okayama and Kochi stops. Hotel Iya Onsen lists Awa-Ikeda, further north on the same line, as its nearest station, though it gives directions by bus from Oboke.
- Oboke sits on the main valley of the Yoshino River; the Iya Valley climbs up a side valley from there. The inns put themselves 10 to 30 minutes from Oboke station by Shikoku Kotsu bus or taxi, and two of the five will collect you if you book.
- The Kazurabashi, a footbridge woven from mountain vines, is in Nishi-Iya. Kazuraya is a 10-minute walk from it and Iya Bijin five minutes by car. Down at Oboke, the gorge sightseeing boats leave two minutes on foot from Oboke-kyo Mannaka, and rafting runs on the Yoshino River.
- By car, the inns give 30 to 50 minutes from Ikawa-Ikeda IC on the Tokushima Expressway. Oboke-kyo Mannaka names Kochi Airport as the nearest airport.
- Two of these inns, Hotel Kazurabashi and Hotel Iya Onsen, run their own small cable cars: one climbs to a bath on the hillside, the other drops to a bath by the river at the bottom of the gorge.
- Prices here are per person with dinner and breakfast, for two sharing. Four of the five list a ¥150 bathing tax per adult on top. Ryokan dinners run to set times, and last check-in is 18:00 or 19:00 at all five, so plan to arrive in daylight.

What we dropped
| Property | Verdict | Why |
|---|---|---|
| Iyakei Onsen Hotel Hikyo-no-Yu | Runner-up (61/100) | At 61/100 it is well behind the five. Rakuten guests score its rooms, bath and dinner 4.23 on average and the hotel 4.18 overall, both the lowest of the six, which costs it on quality and trust despite the lowest weeknight rate. |
| Iwado Onsen Tsurugi-no-Yado Iwado | Outside the theme | 4.17 across 89 reviews, but its listing shows a communal bath and sauna with no open-air bath, and it lies in the foothills of Mt Tsurugi, 25 minutes by car from Sadamitsu station rather than in Iya or Oboke. |
| Oboke Onsen Sun River Oboke | Outside the theme | 4.18 across 1,251 reviews with an onsen, but its cheapest listed rate falls below our ¥8,000 floor. |
| Blue Villa Anabuki | Outside the theme | 4.20 across 170 reviews with an onsen, but its cheapest listed rate falls below our ¥8,000 floor. |
Questions visitors ask
Which one would you book?
Iya Bijin, the top score of the five at 92/100. All nine rooms have their own onsen open-air bath over the gorge, meals are in a private room or at the robata hearth, and its 4.83 across 945 reviews is the highest average here. It runs about ¥23,000–26,000 per person on a weeknight and about ¥27,000 on a Saturday with two meals. It has no pick-up, so if you are coming by train and want to see the vine bridge on foot, Kazuraya scores 89/100.
Which is the cheapest?
On a weeknight, Oboke-kyo Mannaka, from about ¥17,000 per person with two meals. On a Saturday, Kazuraya, from about ¥17,000, with a narrow range of ¥17,000–18,000. Hotel Iya Onsen is the dearest on both: from about ¥25,000 on a weeknight and ¥50,000 on a Saturday.
How do I get from Oboke station to these inns?
Oboke station is on the JR Dosan line. Oboke-kyo Mannaka is five minutes away by car and collects guests if booked. Iya Bijin is 10 minutes by bus or taxi with no pick-up; Hotel Kazurabashi 20 minutes by local bus or 15 by taxi; Hotel Iya Onsen about 30 minutes by Shikoku Kotsu bus. Kazuraya collects you from the Kazurabashi bus stops if you book. Buses in the valley are infrequent, so check times before you travel.
What are the cable-car baths?
Two inns reach their open-air baths by their own small cable cars. At Hotel Kazurabashi it climbs the hillside to a bath with a view over the gorge; at Hotel Iya Onsen it drops to the bottom of the gorge, to a bath fed free-flowing from the source by the river. At Hotel Iya Onsen that bath closes at 21:00 for most of the year and 19:00 from 4 January to the end of February.
Can I walk to the Kazurabashi vine bridge?
From Kazuraya, yes: it is a 10-minute walk. Iya Bijin is five minutes by car from the bridge. Oboke-kyo Mannaka is down at Oboke Gorge instead, two minutes on foot from the sightseeing boats.
When were these prices checked?
We searched Rakuten Travel availability for Wednesdays and Saturdays between 4 November and 26 December 2026, taking the cheapest plan with dinner and breakfast for two adults and showing it per person (checked 26 October 2026). Four of the five list a ¥150 bathing tax per adult on top. Prices move daily — the link on each inn shows today’s.
