Rubaiyat Winery Restaurant (Marufuji)

Rubaiyat Winery Restaurant is part of Marufuji Winery in Katsunuma, home to the Rubaiyat label, one of the Japanese Koshu wines most recognized internationally for helping establish the grape's reputation beyond Japan. The restaurant's lunch course pairs the estate's dry and off-dry Koshu bottlings with a menu that leans French in technique but draws on Yamanashi ingredients, including a grilled Yamanashi trout finished in a Koshu wine butter sauce and a grape-and-cheese dessert plate that showcases the region's fruit-growing alongside its winemaking. The dining room is set within the winery's stone-and-wood buildings, with views over the vineyard from most tables, giving the space a more intimate, boutique character than some of Katsunuma's larger winery restaurants. Reservations are recommended for lunch, since seating is limited and the restaurant draws wine enthusiasts specifically seeking out the Rubaiyat label. Prices span a wider range than some neighboring winery restaurants, from about ¥2,800 to ¥6,500 depending on the course selected. Lunch service runs 11:30am to 2pm within the property's broader 10am–5pm hours, and the restaurant is closed on Wednesdays.
