A soba kappo operating alongside KAI Kusatsu. Inside the beautifully lush, green interior, you can enjoy soba noodles made with locally-sourced, 100% pure buckwheat flour. A la carte dining for lunch and dinner is also available for walk-in guests. (We do not accept reservations.)

For guests staying two or more nights, the dinner on your second night will be served at "Soba Kappo SAI," located right here at KAI Kusatsu. We invite you to experience our "Jigona Kikouchi Soba Kaiseki" (local 100% buckwheat soba course), featuring our signature 100% pure, locally-sourced buckwheat noodles accompanied by three distinct, flavorful dipping sauces.

*The "Jigona Kikouchi Soba Kaiseki" is available exclusively for staying guests.

For our à la carte dinner, we offer a selection of beverages carefully curated by our sommelier. You can fully indulge in each dish at your own pace, pairing them perfectly with your choice of drinks.

*Guests staying with us who prefer the à la carte menu are kindly requested to book a room-only plan (without dinner). *The à la carte menu is also available for non-staying guests. (Please note that we do not accept reservations.)
