Kagetsu (花月)

Kagetsu is one of Nagasaki's oldest ryotei, established in 1642 in the Maruyama district, once the city's licensed pleasure quarter and a historic meeting point for the Japanese, Chinese, and Dutch merchants who shaped Nagasaki's cosmopolitan identity during Japan's period of national seclusion. The restaurant occupies a preserved Edo-period building, and dining here doubles as a visit to one of the city's most significant surviving pieces of that era's architecture and social history. The kitchen serves the full shippoku banquet course, the shared-table format that blends Japanese, Chinese, and Dutch-Portuguese culinary influences into a single meal — the signature dish being the multi-course shippoku set itself, alongside kaku-ni braised pork belly and chawanmushi, a savory steamed egg custard studded with local seafood. The dining rooms are traditional tatami spaces, some overlooking preserved gardens, creating a formal, hushed, and historic atmosphere suited to significant occasions rather than everyday dining. Sake pairings accompany the course, in keeping with the traditional format; this is not a wine-forward establishment. Given both the venue's historic prestige and the complexity of the shippoku course, reservations are required for the dinner course, bookable either by phone or via the restaurant's own website at ryoutei-kagetsu.jp, and booking well in advance is strongly advised, particularly around weekends and holiday periods when demand for one of Nagasaki's most storied dining rooms is highest.
