This winter, 7-Eleven Japan is launching a special soba noodle dish designed to warm both body and soul, available exclusively in the cold region of Hokkaido. It’s called “Kashiwa Soba (Thick-Cut Soba) Made with Hokkaido Buckwheat Flour.” The new item will be rolled out sequentially in stores across Hokkaido starting Wednesday, December 10, 2025.
Japanese convenience stores, affectionately known as “konbini,” are more than just a place for quick essentials. They often feature unique products rooted in the local area, offering an easy way to experience the distinct food culture of that region. Winters in Hokkaido, the vast island in Japan’s north, are particularly harsh, and people naturally crave warm meals. This new product has been launched to meet that very need.
Experience Hokkaido’s Local ‘Kashiwa Soba’ Flavor, Now at Your Convenience Store
The newly released “Kashiwa Soba (Thick-Cut Soba) Made with Hokkaido Buckwheat Flour” is priced at 550 yen (594 yen including tax) per bowl. This dish is 7-Eleven’s carefully crafted recreation of “Kashiwa Soba,” a traditional local cuisine that has long been cherished in Hokkaido.
“Kashiwa” is a term primarily used in Hokkaido and western Japan that means “chicken.” And it’s this chicken that takes center stage in the soba. Slowly simmered in a sweet and slightly rich sauce, the chicken is incredibly tender and comes in a satisfyingly generous portion.
The Noodles are the Star! The Special ‘Thick-Cut Soba’
Another major feature of this product is, as the name implies, the “Thick-Cut Soba.” It is made, of course, with locally sourced buckwheat flour from Hokkaido. Cut thicker than standard soba, these noodles are characterized by their firm, chewy texture and substantial bite. This unique texture gives the noodles a strong presence that stands up to the rich broth and toppings, clearly conveying the developer’s passion to make the noodles the star of the show.
An Exquisite Broth Bursting with Umami
The soba broth, or “tsuyu,” is built on a base of “dashi broth,” the cornerstone of Japanese flavor. This version starts with a flavorful dashi carefully made from bonito flakes and kombu (kelp), and is then enriched with the savory juices from simmering the chicken. The result is a deep, yet gentle-flavored broth that perfectly marries the aroma of the dashi with the richness of the chicken. This broth clings beautifully to the thick-cut soba noodles, warming you to the core with every single bite.

Beyond the new “Kashiwa Soba,” 7-Eleven Japan offers other enticing soba noodle dishes exclusive to the Hokkaido region. Be sure to check them out if you visit Hokkaido.
‘Yubari Curry Soba’: A Bowl Steeped in Coal Mining History
The “Yubari Curry Soba with Hokkaido Buckwheat Flour” is priced at 540 yen (583.20 yen including tax). This isn’t just any curry soba. It’s a dish with a rich historical background, recreating the “Tanko-meshi” (Coal, Iron, and Port Town Meals) that once served as a source of stamina for the laborers in the coal, steel, and port industries—known collectively as “Tanko”—which were foundational to Hokkaido’s modern development.
The thick, spiced curry broth strikes a perfect balance between the flavor of the dashi and the richness of soy sauce. It’s slightly spicy, yet it has that nostalgic, dashi-infused flavor characteristic of Japanese curry udon and soba. Enjoying a bowl while reflecting on this history adds another layer to the experience.
‘Kakiage Soba’: A Classic That Showcases Quality
The “Kakiage Soba with Hokkaido Buckwheat Flour” is available for 500 yen (540 yen including tax). “Kakiage” is a type of Japanese tempura made by gathering finely chopped vegetables, seafood, or other ingredients into a patty with batter and deep-frying it. Serving it on top of warm soba is a classic style beloved all across Japan.
This dish, with its smooth noodles and a flavorful broth that highlights the umami of the bonito dashi, is a simple yet high-quality offering. The use of Hokkaido-grown buckwheat flour is another touch that speaks to the region’s unique commitment to quality.
A Message from the Developer
The developer in charge of the “Kashiwa Soba” expressed a desire “to deliver a product that warms customers’ bodies and souls from the very first bite.” Taking a hearty bite of the substantial, thick-cut noodles soaked in a piping hot broth, along with a generous portion of chicken. It’s an experience that promises to deliver the ultimate sense of satisfaction and happiness that can only be found on a cold winter day.
If you’re lucky enough to find yourself in Hokkaido this winter, be sure to stop by your nearest Japanese 7-Eleven. This special bowl, which you can only find there, is sure to make your trip even more memorable.
