Alongside sushi-making, participants will explore the traditions and history of Yamanashi's unique cuisine. The class includes an introduction to pairing sushi with local sake, offering insights into flavor combinations. Vegetarian options are available upon request. This cultural and culinary experience, set against the stunning backdrop of Mt. Fuji, provides practical skills and unforgettable memories.
