Zonbun | Kinmedai Specialty Japanese Seafood Izakaya in Shinjuku

Located in the heart of Shinjuku, Zonbun is a specialty Japanese izakaya that focuses on premium Kinmedai (splendid alfonsino) dishes.
We welcome a wide range of guests—from international travelers and business professionals to local regulars.
Our clean, peaceful space combines traditional Japanese aesthetics with carefully prepared cuisine to create a relaxing dining experience.

One of our key attractions is the opportunity to enjoy Japan’s unique “izakaya style” dining—sharing seasonal dishes, sipping sake, and enjoying warm, casual conversation.
It’s an experience that allows guests to truly connect with the depth and charm of Japanese food culture.

At Zonbun, our signature ingredient is Kinmedai, a prized deep-sea fish known for its rich flavor and delicate texture.
Each morning, our head chef personally selects the finest catch at Tokyo’s Toyosu Market, choosing only the best for our kitchen.
We offer Kinmedai prepared in a variety of ways—sashimi, simmered, grilled, and shabu-shabu.

Among these, the Kinmedai Shabu-Shabu is especially popular for its refined taste and vibrant presentation—delighting both the eyes and the palate.
With subtle seasoning that enhances the natural flavors, every dish lets you savor the true essence of this exceptional fish.

At Zonbun, we specialize in Kinmedai and offer a wide variety of seasonal seafood and traditional Japanese cuisine.
Our signature Kinmedai Shabu-Shabu stands out as a guest favorite, alongside sashimi platters, grilled fish, small seasonal dishes, and more.
Each dish is designed to bring out the natural flavors of the ocean and pairs beautifully with carefully selected Japanese sake.
It’s a complete seafood experience that showcases the richness of Japan’s culinary heritage—right in the heart of Shinjuku.
