It has been loved by locals for many years. This time, you can enjoy it in a tsukemen style, combining flavorful soba noodles made with Hokkaido-grown buckwheat flour with "Kashiwanuki," which consists of chicken and green onions served in a rich soup flavored with umami-rich tamari soy sauce. Please enjoy the rich local food culture at Seven-Eleven.

The dipping broth has a rich flavor combining umami-rich dashi made from kelp and bonito flakes with deeply savory tamari soy sauce. This satisfying dish features chicken and green onions simmered in the umami-rich dashi and generously served. Furthermore, because it is a tsukemen style using Hokkaido-grown buckwheat flour, which condenses umami and sweetness due to large temperature differences, you can further enjoy the unique rich aroma and firm texture of soba noodles.
