A Refined Dining Experience Around the FireWood-Fired Dining on the Lake

In a restaurant arranged around the glow of a wood-fired oven, warm, aged materials set the stage for a special dining experience surrounded by the warmth of flickering flames and the subtle aroma of wood smoke. Blending Japan's traditional "wa-modern" beauty with the warm simplicity of Scandinavian style, it offers a calm setting in which to slow down and enjoy the meal.

Chef's Commitment

Wood Fire Brings Out the True Flavor of Each Ingredient

Chef Kinjo, who leads the KOS kitchen, cooks authentic wood-fired cuisine, using wood fire throughout the cooking process.
Spices and herbs are kept to a minimum, letting the natural flavor and aroma of each ingredient take center stage.
Because we value local sourcing and seasonality, the menu changes depending on the ingredients available on any given day.
To keep the smoky character of the wood from lingering too strongly, a light palate-cleansing dish is served between courses, so you can enjoy every bite through to the end while maintaining balance throughout the meal.
With full ventilation and air conditioning in place, you can take in the atmosphere of a wood fire without any smoke drifting into the dining room.

Signature

Carefully Selected Ingredients & Wine

Koshu Wine Beef
