KAI Ito: An Izu Ryokan 30 Rooms Wide, Built for Seafood

KAI Ito (界 伊東) is on the Izu Peninsula in Shizuoka Prefecture — an area the ryokan itself describes as rich in golden eye snapper, Ise lobster, abalone and wagyu beef. It runs 30 rooms with an occupancy of 1 to 8 guests, which makes it one of the more flexible properties in the KAI collection and a practical base for exploring Izu by car.

Izu is the peninsula south-west of Tokyo, reached either by the Tokaido line down the coast or by road through Numazu. It is one of the few places within easy reach of Tokyo where you can combine a hot-spring town, a working fishing port and a volcanic coastline in a single two-night stay.

Getting there

By car

From the Tomei Expressway, take the Numazu Interchange and continue down the peninsula. The property offers an exclusive car-rental discount, and — because Izu's best beaches, viewpoints and seafood ports are spread along the coast — we generally recommend having a car here rather than relying on the train.

By air

The property also lists access from Haneda Airport, which is the practical route if you are flying into Tokyo and heading straight to Izu.

The baths

The signature of the bathing here is a hot spring that bubbles up constantly from the centre of the indoor bath — the source is in the room, not piped in from elsewhere. It is a small detail that changes the character of the soak: this is the water as it comes out of the ground.

Izu as a destination

Izu is a peninsula of contrasts — the eastern coast is developed and easy, the west is wild and scenic, and the interior is mountains and wasabi fields. The seafood is the reason many guests come: kinmedai, Ise lobster and abalone are Izu specialities, and the ryokan builds its meals around them.

Planning an Izu trip around it

Izu works as a self-drive loop out of Tokyo — the east coast down, the west coast back, with a hot-spring night in the middle. Every itinerary we build is designed from scratch around your dates and your group; there is no fixed departure and no group to join: have an Izu itinerary designed for you — free, no obligation.

We plan private journeys for travellers worldwide, in any destination. Nothing about our trips is off-the-shelf.
