Big windows frame olive groves and the Seto Inland Sea; there are a herb bath, waterfall shower and sauna. The water is a radioactive (radon) spring.

Closed all day Wednesday, and the onsen only on Thursday (holidays vary). Five minutes by car from Kusakabe port, ten from Ikeda port.

Floor-to-ceiling glass indoors and the outdoor bath frame the archipelago of the Inland Sea, with the sunset the star. The park's Greek windmill, the live-action 'Kiki's Delivery Service' film set, Olive Memorial Hall and herb garden make it the hub of Shodoshima sightseeing. Hours shortened since July 2026 owing to fuel supply
- Spring water
- Shodoshima Olive Onsen, a sodium-chloride cold mineral spring (a cool source heated for use; check on-site notices for the full analysis), recirculated and disinfected. The salt retains warmth, and the olive-leaf herbal bath is fragrant and said to moisturise the skin. Indicated for neuralgia, muscle pain, poor circulation and fatigue. Hot springs are scarce across Shodoshima, making this the one scenic onsen easy to fit into a sightseeing day

An island bath watching the sun set over the Inland Sea beyond the olive groves
Shodoshima Olive Onsen Sun Olive is a view bath standing on the hill of the 'Michi-no-eki Shodoshima Olive Park', birthplace of olive growing in Japan, on Shodoshima island in Kagawa. The park — white Greek windmill, olive groves, the set from the live-action 'Kiki's Delivery Service' and a herb garden — is the hub of Shodoshima tourism, and from the glass-walled bath hall and rotenburo at its highest point the islands of the Seto Inland Sea and the setting sun spread out beyond silvery olive leaves. Alongside a jacuzzi, lying bath, cascade, mist sauna, dry sauna and outdoor bath there is a fittingly local 'olive-leaf herbal bath', eight tubs in all, and the salty water holds its warmth. Hot springs are almost absent elsewhere on the island, so this is virtually the only choice to close a day touring Angel Road, Kankakei Gorge and the Twenty-Four Eyes film village. Note, however, that since 17 July 2026 fuel-supply problems have cut hours to 15:00–20:00 (last entry 19:30) for an undetermined period — check the official site to see whether normal hours (12:00–21:00) have resumed before you go. Closed Wednesdays and Thursdays; adults ¥1,000, children ¥700.
Eight baths, the olive herbal tub and sunset from the rotenburo
From the Olive Park car park, pass the windmill and climb to the white building at the top of the park, buy a ticket at the front desk and stow your bags in a locker (¥100 refundable). The gender-separated indoor halls face the sea through broad floor-to-ceiling glass, so even from the jacuzzi you see the Inland Sea and the islands opposite. Warm up in the lying bath, cascade and mist sauna, then step into the island's own 'olive-leaf herbal bath' with its faint grassy scent — the leaf extract is said to smooth the skin, and it is popular with women. After the dry sauna, head out to the rotenburo. The rock-rimmed outdoor pool is not large, but below it the olive slopes fall away to open sea and sky, and at dusk you can watch the archipelago turn orange from the water. With the current shortened hours opening at 15:00, timing the sunset (about 19:00 in summer, 17:00 in winter) is easy — just do not miss the 19:30 last entry. Afterwards browse olive oil, olive hand cream and somen noodles in the shop, or try olive somen and Shodoshima soy-sauce dishes in the restaurant. See the park's windmill and the 'Kiki' broomstick photo spot before sunset, then bathe — the efficient order. The changing room is on the small side and crowds when a group arrives.
Practical details and two days on Shodoshima
Since 17 July 2026 hours are temporarily shortened to 15:00–20:00 (last entry 19:30); normal hours are 12:00–21:00, closed Wednesdays and Thursdays (changes on holidays). Adults ¥1,000, children 4 to elementary ¥700. Always check the notices on the official site (olive-pk.jp) just before visiting. From Takamatsu port, ferries take an hour to Kusakabe (5 min by car), Sakate (10 min) or Tonosho (25 min); continue by rental car or Olive Bus, or rent a bicycle at the park's cycling terminal. A suggested two days: Day 1 Takamatsu to Tonosho port, Angel Road (a sandbar walkable only at low tide — check tide times), the Marukin soy-sauce museum and soy-brewery quarter, the Twenty-Four Eyes film village, a stroll in Olive Park and a sunset bath at Sun Olive, overnight on the island; Day 2 the Kankakei ropeway (superb autumn colour), the Nakayama rice terraces and rural kabuki stage, the 'maze town' of Tonosho, and the ferry home. In Setouchi Triennale years (every three years; next 2028) the whole island is busy and lodgings sell out early. The onsen's charm lies in the view and the olives rather than the scale of its facilities — come to round off an island trip lightly, not for a luxury spa. Check the tattoo policy on site.
