Zakuni is a traditional regional dish from Gunma Prefecture.
In Gunma, there is a custom of eating Kenchin jiru (a vegetable soup) during special occasions, and Zakuni is a similar dish that has been passed down in the city of Takasaki. Unlike Kenchin jiru, Zakuni is made without oil. This is said to reflect a wish for marital harmony, as the dish was traditionally served at weddings—symbolizing the hope that the couple would not become like water and oil, a Japanese metaphor for people who do not get along.

Zakuni is also enjoyed as part of New Year’s osechi cuisine, and is served during Setsubun and celebratory gatherings. The broth is made using dried squid (surume), and the rich umami of surume soaks into the vegetables, making it a deeply satisfying and comforting dish.
