One of the greatest charms of Japanese convenience stores is the “regional limited fair,” where you can find special products available only in that area. This time, we’re introducing an event focused on Chiba Prefecture—a region that, despite being next to the metropolis of Tokyo, boasts abundant nature and a unique food culture of its own.
From October 7 to October 20, 2025, the “Chisan-Chisho Fair” will be held exclusively at 7-Eleven stores throughout Chiba Prefecture. “Chisan-Chisho” is a Japanese phrase meaning “locally produced for local consumption,” representing an initiative to support wonderful local ingredients. For travelers, this is an unparalleled chance to easily experience Chiba’s authentic “gotochi gourmet” (local gourmet) without having to visit a restaurant.
A Detailed Introduction to All 7 Products at the Fair
This fair features a lineup of seven products, from bento boxes and ramen to delectable sweets, all making the most of Chiba’s bounty.
1. Charcoal Grilled Chicken Bowl (using Boso Herb Chicken)
First up is a luxurious rice bowl featuring Chiba’s premium brand chicken, “Boso Herb Chicken.” Raised on a diet including herbs, this chicken is healthy, free from strong poultry smells, and has a characteristically plump and tender texture. For this dish, each piece of breast meat is carefully grilled over a charcoal fire, rendering out excess fat and imparting a wonderful smoky aroma. It’s tossed in a sweet and savory soy sauce-based glaze designed to perfectly complement the rice. Though it’s a healthy option, it is incredibly satisfying, making it a perfect and fulfilling meal during a busy day of sightseeing.
2. Kurouma Soup Takeoka-style Soy Sauce Ramen
This is an authentic recreation of “Takeoka-style” ramen, a very unique and passionately loved local ramen born in the Boso Peninsula area of Chiba. Its most striking feature is its jet-black soup. This soup is made simply by diluting the rich, savory soy sauce liquid used to simmer “chashu” (braised pork) with hot water. Contrary to its appearance, it is not overly salty; instead, it has a surprisingly deep and mellow richness, condensed with the umami of pork and the fragrance of soy sauce. The noodles are chubby and chewy to stand up to the bold soup. Experience for yourself the one-of-a-kind local flavor that Chiba’s ramen lovers adore.
3. Boso Herb Chicken and Gobo Onigiri
A nostalgic-tasting onigiri (rice ball) featuring “tori-gobo gohan,” a classic Japanese home-style dish. “Gobo” is burdock root, an essential ingredient in the Japanese diet known for its unique earthy aroma and crisp texture. For this dish, flavorful Boso Herb Chicken and gobo are cooked together with rice in a soy sauce-based dashi broth, allowing their flavors to infuse into every single grain. It’s a conveniently sized snack that is truly packed with the bounty of Chiba.
4. High-Protein Spicy Chicken Breast with Onsen Tamago and Natto
For the health-conscious, this is a perfect choice, centered around Japan’s iconic health food, “natto” (fermented soybeans). It features healthy Boso Herb Chicken breast, stir-fried with gochujang (Korean chili paste) for a spicy kick. On top sits a creamy, soft-cooked “onsen tamago” (hot spring egg). The best way to eat it is to mix everything together just before you dig in; the flavor of the natto, the umami of the chicken, and the mellowness of the egg combine to create a complex and deeply delicious taste.
5. Rich and Creamy Milk Mousse “Moko”
This is a Chiba-exclusive flavor of 7-Eleven’s super-popular “Moko” dessert series. The “Moko” is known for its special “mochi-mochi” (chewy) cream puff shell. Inside this unique shell is an incredibly rich and creamy milk mousse, made with a generous amount of fresh milk from Chiba Prefecture. The mellow and gentle sweetness of the milk fills your mouth, making it a truly blissful dessert.
6. Moist Whipped Cream Roll made with Milk
This is a product that captures the deliciousness of Chiba within the bread itself. By using milk from Chiba Prefecture instead of water when kneading the dough, the bakers have achieved an incredibly “shittori” (moist) and soft texture. A generous amount of rich yet light milk-flavored whipped cream is sandwiched inside this special bread. While simple, it allows you to directly enjoy the full flavor of the milk, satisfying both bread and sweets lovers.
7. Sweet Potato Pudding using Chiba-grown “Beni Haruka”
If there’s a king of autumn flavors in Japan, it’s the “satsumaimo,” or sweet potato. Among them, the “Beni Haruka” variety is famous for its extremely high sugar content and sticky, honey-like texture. This pudding is a luxurious, “all-things-sweet-potato” dessert, using Chiba-grown Beni Haruka in both the pudding at the bottom and the whipped cream on top. With the rich natural sweetness of the sweet potato and a smooth, melt-in-your-mouth texture, this is an irresistible autumn treat.
