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 sticky. Approximately 30 pieces are generously served, with a mound of 'Toro-taku' made from the finest bluefin tuna from 'Yama Ko', said to be the best in Japan, towering in the center. The sticky texture and sweetness of the Yoichi sweet shrimp paired with the Toro-taku from 'Yama Ko' create a perfect match that provides great satisfaction. With impressive visual impact and generous volume, this dish allows shrimp lovers to indulge in a mouthful of sweet shrimp.

Our bluefin tuna is sourced from 'Yama Ko', a tuna wholesaler said to be the best in Japan, located in Toyosu. They are a professional group of tuna experts featured in the media. Most Michelin-starred sushi restaurants across the country use 'Yama Ko' bluefin tuna, and we, as sushi lovers, are so fond of 'Yama Ko' bluefin tuna that we were able to introduce it through acquaintances at sushi restaurants. I don't think there are any seafood bowl shops using '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! Recommended toppings include large scallops, extra salmon roe, and half shrimp… 2,750 yen

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 provide 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 cramming them into small barns, the cattle grow up happily, eating delicious water and grass, and playing around in spacious exercise areas, just as the name Shimizu Town suggests. Taking over 36 months to grow without stress or physical burdens results in delicious beef. The non-heated beef toro flakes, which are completely uncooked, pair perfectly with toro taku! Enjoy the rich flavor and depth, as well as the melt-in-your-mouth texture. We recommend serving it with white rice! Recommended toppings include sea urchin, large scallops, and sweet shrimp - half portion... 2,200 yen.

This is a carefully opened, thick and fatty rare large-sized true hokke, caught in Shakotan from Yoichi, and prepared by hand. The flavor is maximized through thorough control of humidity, airflow, and temperature, resulting in the 'Yoichiya Special One-Night Dried Fish.' The 'hokke' caught near Yoichi is particularly large, thick, and has excellent fat content.

The perfect saltiness beautifully brings out the original flavor of the hokke. Delicious dried fish is made possible because fresh fish is carefully dried by skilled artisans. *Please note that we use 'true hokke' and not 'shima hokke.'

The reason why Uni-ji started a sea urchin specialty shop in Yoichi Town was that no one knew about Yoichi sea urchin. However, Yoichi sea urchin has a high taste evaluation, and the summer sea urchin is traded at a high price in Hokkaido, mostly sent to the Kanto region, resulting in little local consumption and low recognition. Yoichi sea urchin is characterized by its refined sweetness and the lingering flavor of the sea, and Uni-ji believes that Yoichi sea urchin is delicious. We wanted as many customers as possible to taste it in our hometown of Yoichi. This is the best sea urchin bowl that we want everyone to try at least once. The bowl features two types of fresh sea urchin: purple sea urchin and bafun sea urchin, as well as two types of grilled sea urchin: purple sea urchin and bafun sea urchin, making a total of four types to compare. This is a menu exclusive to the Yoichi family store. Recommended toppings include large scallops, extra salmon roe, and half botam shrimp.
