About this ryokan

🌊An inlet inn on the Kurushima Strait with live-tank seafood and a seawater bath

Ehime · Kaishuku Sennenmatsu

A seaside inn named after a thousand-year pine

🌲The inn takes its name from a pine nearly a thousand years old that stood on this site until 1977.
🏞️It sits alone in an inlet inside Setonaikai National Park, facing the Kurushima Strait, one of Japan's three great tidal currents, with Mt. Tateyama behind.
🏡Located on Oshima island along the Shimanami Kaido, it aims to feel like a hometown you return to.

Manten-no-yu seawater open-air bath

♨️The open-air bath uses seawater pumped up from the Kurushima Strait right in front and heated.
🪨The tub is built from large boulders of natural granite, which Oshima is known for producing.
🌌Soak while watching the sunrise or sunset, a sky full of stars and the night lights of Imabari across the water.

Bath facilities and amenities

🛁A new reclining bath was added to Manten-no-yu in November 2025.
🧴Shampoo and conditioner are by napula, and body wash is by Coconatura.
🪥Bath towels, face towels, toothbrushes, razors and other amenities are provided.

Ocean views from every room

🌅All rooms face south over the sea, so you can watch the water change from sunrise to sunset.
🛏️Western-style twin design rooms are finished with Ozu washi paper and plaster art and have a terrace (2–3 guests).
🎎Japanese rooms include ones with a unit bath (3–5 guests), large two-room suites of 14–18 tatami (4–6 guests) and smaller 10-tatami rooms (3 guests).

Straight from the live tank

🐟Fish landed almost daily from the Kurushima Strait by local fishermen are kept in tanks and cooked right away.
📋There is no fixed monthly menu; the chef decides how to cook each morning based on the fish, served as an omakase course.
🎣Seasonal catches include wild red sea bream (spring and autumn) and akou grouper (summer).

Horoku-yaki and sea bream rice

🔥Horoku-yaki, a Kurushima Strait specialty said to have been eaten by the Murakami pirates to celebrate victories, is roasted using only the sea bream's own moisture.
🍚Kamadaki tai-meshi is a whole sea bream cooked in a pot of rice with carefully made dashi and local fried tofu.
👶Children's meals and celebration courses such as a 100th-day baby feast are also available.

Sea activities and surroundings

🏖️A beach is a 30-second walk from the entrance, and you can swim in the sea in summer.
🛶Diving, trial diving, sea kayaking, SUP and fishing can be booked in advance (paid).
🚢The Kurushima Strait is an international shipping lane, so many ships pass by in front of the inn.

Getting there

🚌From Imabari Station take a bus to the Kameyama stop; from the Hiroshima side take a bus from Fukuyama or Onomichi Station to the Oshima stop.
🚗About 10 minutes by car from Oshima-minami IC on the Shimanami Kaido, or about 20 minutes from Oshima-kita IC.

An island inn where live seafood from the strait and a heated seawater bath come together. The bath is seawater rather than a natural hot spring, and the inn has regular closing days, so check the business calendar.
