What is KAI?

What is KAI?

Japan’s hidden luxuries—at your fingertips

KAI is a leading brand of upscale boutique hot spring ryokans. Every establishment offers a contemporary take on the traditional Japanese inn, providing unique, location-specific experiences. From exclusive activities to specialty suites, KAI is an invitation to immerse yourself in the rich diversity of Japanese culture.


The spacious rooms are designed in classic Japanese style and feature both a bedroom and living room. In-room baths made of ancient cypress are fed by the Ito Hot Spring; in many rooms, they overlook a Japanese garden that blooms with flowers all year round.

KAI Signature Rooms

KAI Signature Rooms incorporate elements of regional craft cultures in their design. At KAI Ito, the "Izu Flower Calendar" rooms are designed to express the flowers of the region's four distinct seasons. Guests can experience the rich natural beauty that changes throughout the year from the comfort of their room.
