Sweet shrimp account for about 70% of the total catch in Hokkaido, and Yoichi Town boasts the third highest catch in the country. Yoichi sweet shrimp are highly prized for their strong sweetness and high quality, with most being shipped to Toyosu, making them quite rare. When you sprinkle salt on these Yoichi sweet shrimp and let them rest a bit, their sweetness intensifies and the texture becomes rich and creamy. Approximately 30 pieces are generously served, with a mound of the finest tuna belly from 'Yama Ko', said to be the best in Japan, towering in the center. The rich texture and sweetness of the Yoichi sweet shrimp combined with the tuna belly from 'Yama Ko' create a perfect match that provides great satisfaction. The visual impact and volume are both outstanding, making it the ultimate dish for shrimp lovers, allowing you to indulge in a mouthful of sweet shrimp. Half portion... 3,850 yen Recommended toppings: Botan shrimp, large scallops, sea urchin. *Due to rising raw material prices, some menu prices will be revised starting November 1, 2025.

Our bluefin tuna is sourced from 'Yama Ko', a tuna wholesaler said to be the best in Japan, located in Toyosu. They are a group of tuna professionals. Most Michelin-starred sushi restaurants across the country use 'Yama Ko' bluefin tuna, and even Uni Ji, a sushi lover, is so fond of 'Yama Ko' bluefin tuna that we were introduced to a sushi restaurant by an acquaintance and were able to use it. I don't think there are any seafood bowl restaurants that use 'Yama Ko' bluefin tuna. This dish allows you to compare five types of aged bluefin tuna: 'Akami' (lean), 'Chutoro' (medium fatty), 'Otoro' (fatty), 'Aburi' (seared), and 'Toro Taku' (fatty tuna with pickled vegetables), which is irresistible for tuna lovers. Be sure to try the Toro Taku wrapped in seaweed! Half... 2,750 yen Recommended toppings: large scallops, extra salmon roe, sweet shrimp.

The Uni Toro Salmon Bowl was created from customer feedback. It features popular salmon sashimi and the highest quality uni selected by our exclusive buyers at Seiichiya, all in one bowl. The rich flavor of toro salmon is luxuriously topped with three types: raw, marinated, and seared. The toro salmon has a refined and rich taste that melts in your mouth. Marinating intensifies the flavor, significantly enhancing its deliciousness. The seared version offers a delightful roasted aroma, providing a rich yet pleasantly light taste. Eating uni and salmon together creates a perfect blend of the mellow umami of salmon and the rich, sweet flavor of uni. The fat from the salmon enhances the creaminess of the uni, resulting in an incredibly luxurious taste.

We have finally added eel to the menu, which has received a lot of feedback from foreign tourists. Our Unaju features domestically sourced eel, with our proud sauce and carefully selected ingredients including sansho pepper. The eel is fluffy, with a crispy skin, and we have experimented with plating it so that half is presented skin-side up to enhance the crispy texture. Eel is rich in vitamins and collagen, and while it is fatty and the flesh is tender, it is surprisingly low in calories, making it a delightful ingredient for women. Above all, the 'Unaju' topped with glossy special sauce over rice is exquisite. Recommended topping: extra eel.

If we are going to feature unagi rice on the menu, we wanted to combine it with our essential sea urchin, which is a pride of our restaurant. We have created a unagi rice box with a focus on quality.

Our beef toro flakes are made from beef processed in Tokachi Shimizu Town. This beef is raised based on the desire of 'Born Free', prioritizing healthy cattle rearing. The pastures that grow the feed for the cattle are free from pesticides and minimize chemical fertilizers as much as possible. There is a commitment to the rearing process as well. Instead of being crammed into a small barn, the cattle grow up happily, eating delicious water and grass, and playing energetically in the exercise area, just as the name Shimizu Town suggests. Taking more than 36 months to grow without stress or physical burden results in delicious beef. The non-heated beef toro flakes, which are completely uncooked, pair perfectly with toro taku! Enjoy the rich flavor, depth, and melt-in-your-mouth texture. Half... 2,200 yen Recommended toppings: Sea Urchin, Large Scallops, Botan Shrimp. *Due to rising raw material prices, some menu prices will be revised starting November 1, 2025.

You can now enjoy a half-and-half serving of Tokachi Beef Toro Flake Rice Bowl and specially selected sea urchin from Seiichiya!

They wondered if it could be made half and half since you can't eat that much sea urchin as a topping. In response to these luxurious requests, we have created a rice bowl topped with half Tokachi Beef Toro Flake and half sea urchin! The moment you take a bite, the melt-in-your-mouth flavor of the beef spreads throughout your mouth, and when eaten with the sea urchin, it adds a rich sweetness that is exquisite!
