Iya Onsen Day Trip: Cable Car, Bath Options and How to Get There

Checked: September 27, 2026

Hotel Iya Onsen sits above the Iya River, deep in Tokushima’s mountain valley. The headline experience starts in the hotel: a small cable car descends about 170 metres down a steep slope to the riverside bath. The ride takes roughly five minutes each way, so this is not a quick soak to squeeze between two nearby sights. Give it a proper half-day, especially if you are relying on a bus.

Which day-use ticket makes sense?

The standard adult ticket is ¥2,000 and includes the cable-car ride, the open-air bath by the river and the indoor panoramic bath. Children pay ¥1,000. If you only want the indoor bath, admission is ¥700 for adults and ¥300 for children; that ticket does not include the cable car or riverside bath.

The river bath is the reason most visitors make the trip. It uses alkaline simple sulfur spring water, listed at about 38°C at the source, and the hotel identifies the outdoor bath as free-flowing source water. That source temperature is not a promise that every pool will feel exactly 38°C: the open-air bath is affected by the weather and the water in the pool. The indoor bath is heated and recirculated, so it is a different experience.

Two riverside baths, Keikoku-no-yu and Seseragi-no-yu, alternate between men and women each day. If you have a particular view in mind, check the hotel’s day-use calendar before travelling. The private open-air bath is a separate option: it costs ¥3,000 per 60-minute session before tax, plus the regular admission for each person. Day visitors cannot reserve it in advance; availability is decided at the hotel after arrival.

Allow for the cable car and the valley’s pace

Day-use bathing is listed from 7:30 am to 5 pm, with last admission at 4 pm. Wednesday is the regular closing day; when it falls on a public holiday, the day off may move. The indoor bath closes for cleaning from 10 to 11:30 am. The hotel also publishes monthly calendars and notices for maintenance, weather and road works. Check those just before leaving, because a cable-car repair can affect access to the riverside bath even if the hotel itself is open.

Once you descend, the riverside setting is the point: there is time to bathe, ride back up and look over the valley, but little reason to rush through the visit. The hotel’s full ticket includes both bathing areas, so you can use the indoor bath before or after the cable-car trip, keeping the cleaning window in mind.

Getting there without a car

Shikoku Kotsu serves the valley, but the route structure changes on October 1, 2026. Until September 30, the Iya Line runs between the Oboke area and Hotel Iya Onsen. From October 1, the Nishi-Iya Line increases from six to eight round trips, and a separate Iya Gorge Line begins running three services each way between Kazurabashi Yumebutai and the hotel. The Iya Gorge Line does not run on January 1.

Check the post-change timetable for your date and plan around the return connection first. The nearby Peeing Boy Statue is about a five-minute walk from the hotel.

The hotel’s own station shuttle is one trip each way: a reserved pickup at Oboke Station at 3:10 pm and a 9:50 am departure from the hotel the next morning. That schedule is designed around overnight stays, not a typical day visit. Call the hotel before treating it as an option for a day trip.

Driving gives more control over the day, though the roads are narrow and winding. Leave extra time for passing oncoming traffic, roadworks and weather. The hotel has 37 free parking spaces, available first come, first served. In winter, the hotel advises visitors to bring suitable vehicle equipment because snow can fall from December through March.

A good fit for a destination bath, less so for a spare hour

Choose Iya Onsen when you want the river setting and cable-car descent to be part of the outing. It can pair with Oboke Gorge or the vine bridge, but public transport timing may decide how long you have at each stop. For a station-side bath, several saunas or a flexible afternoon, the trip into the valley is a lot of effort for a short soak.
