Welcome to SE-NO-UMI(磯の宿 石花海)

“Senoumi” is a shallow seabed spreading along the coast of Izu.


The shoal with rich marine life is a good habitat for fish. Good fish caught at Inatori Fishery Port in the morning are cooked for your dinner in our ryokan. Our specialty, “Grilled Seafood Fishermen’s Special,” and many other kinds of seafood will please your palate. In addition, our hospitality includes a splendid view of the sweeping expanse of the sea in front of our ryokan. You can enjoy the magnificent view of the sea from the lobby and also from baths facing the ocean. You will feel relaxed as if being embraced by the sea.
