Savor fresh fish landed at Inatori Fishing Port and unwind with breathtaking ocean views.

“Seno-umi” refers to the underwater hills that spread across the seabed off Izu. The rich shallows are an ideal home for fish. Our inn also receives delicious seafood landed at Inatori Fishing Port. Please take your time savoring the bounty of the sea, including our signature fisherman’s grill. Above all, our finest hospitality is the vast ocean right before you. Magnificent views unfold from the lobby and from the panoramic bath. We hope you will relax with a generous, open feeling—as if embraced by the sea. Soak in our free-flowing Onsen straight from the source while gazing at the ocean, and you’ll soon forget everyday fatigue. At Inatori Onsen Seno-umi, even the corridors are covered with tatami mats—please enjoy your stay barefoot and at ease.

  • It was the best birthday ever.

    All the hotels are excellent. The rooms and the large public bath were wonderful, but what surprised me most was the luxurious dinner. We had been planning a winter vacation, but due to my son's fever, we had to cancel the trip and were feeling down. So, we decided to plan a sudden trip to Izu for my husband's birthday celebration. Even though it was a last-minute reservation made the day before, they prepared a birthday cake for us and two lovely staff members sang a BIRTHDAY song for him, which made my husband very happy. Thank you also for guiding us to such a beautiful room! It became an unforgettable memory for us.
