玄海についてAbout Genkai

Genkai has been dedicated to Mizutaki for over 90 years since its founding in 1928 (Showa 3).
Our signature milky-white soup, carefully refined over generations, is rich in the natural flavor of chicken, collagen, high-quality fat, and well-balanced nutrients. Each sip offers a deep, savory richness and an elegant aroma.

Our menu features seasonal dishes made with the finest ingredients, including Mizutaki Kaiseki and a variety of chicken specialties that reflect the flavors of each season.
The chicken used for our Mizutaki is “Date-dori”, delivered fresh from the fertile lands of the Date region in Fukushima Prefecture, nestled between the Ou and Abukuma mountain ranges.
Enjoy its firm texture and clean taste, free from excess fat or odor.


お料理Menu

Mizutaki is a traditional Japanese hot pot dish that originated mainly in Kyushu and the Kansai regions, and is now enjoyed throughout Japan.As its name suggests—literally meaning “boiled in water”—the dish is prepared by simmering ingredients in water to create a delicate broth, enjoyed together with vegetables.
Among various ingredients, chicken is most commonly used, as it releases the richest flavor when cooked in this way.In Tokyo, we believe it was our founder, Hiroo Yano, who first introduced Mizutaki to the city.

食の未来提案Initiatives for the Future of Food

Japan’s food self-sufficiency rate stands at 37%; we rely on overseas sources for more than 60% of the food we eat.As of 2022, the agricultural workforce numbered 1.23 million, with an average age of 67.9. It is predicted that if the current trend continues, the number of farmers will drop below 300,000 within twenty years.This is not a distant problem.While the self-sufficiency rate for chicken is 66%, the vast majority of the feed used to raise the birds is imported. If feed imports were to halt, the effective self-sufficiency rate for chicken would plummet to below 10%. The risk that the foods we eat every day might suddenly become unavailable is quietly mounting.Genkai, a restaurant that has been serving mizutaki (chicken hot pot) in Shinjuku for 97 years, could not simply view this issue as someone else's problem.
