Highlights

13SKY JACUZZI

On the spiral rooftop above the wellness area is a jacuzzi shaped like Zao's Okama crater lake. From here, you can enjoy panoramic views that are stunning whether at sunrise, sunset, or night.

23ROOMS

Rooms feature a crimson color scheme—inspired by the area's safflowers—and elegantly shaped furniture courtesy of artisanal woodworkers Tendo. Windows look out over Zao's scenic landscape.

33KAISEKI

Dinners are inspired by Buddhist cuisine and consist of healthy, colorful dishes featuring seitan, edible chrysanthemum flowers, and other regional specialties, served on vibrant red lacquerware.

Rooms

KAI Signature Rooms offer a deeper dive into the local culture. Here, the rooms highlight the design sensibilities of the area's artisans through rug tapestries, wood ikebana sculptures, and washi paper lampshades inlaid with safflower petals.
