Our bluefin tuna is sourced from Yamako, the 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 bluefin tuna from Yamako, and even Uni-ji, a sushi lover, is so fond of Yamako's bluefin tuna that we were able to introduce it to a friend’s sushi restaurant and use it. I don't think there are any seafood bowl restaurants using bluefin tuna from Yamako. This dish allows you to compare five varieties of aged bluefin tuna: 'lean', 'medium fatty', 'fatty', 'seared', and 'toro-taku', 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.

Sweet shrimp account for about 70% of the total production in Hokkaido, and Yoichi Town boasts the third highest catch in the country.

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.

This is a carefully opened, thick and fatty rare large-sized true hokke, caught in Shakotan from Yoichi, and meticulously 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 Town is particularly large, thick, and has excellent fat content. This exquisite dish is made by opening the fresh 'true hokke' from the back and drying it overnight with only 'sea salt' and 'cold wind.' The skin of this opened hokke is also very delicious. The moderate saltiness beautifully brings out the original flavor of the hokke. Delicious dried fish is possible because fresh fish is carefully dried by artisans. *Please note that we use 'true hokke' and not 'shima hokke.'
