A new addition is joining the immensely popular “Gokuuma Kurobutaman” steamed bun series from the Japanese convenience store, FamilyMart. Its name is “Gokuuma Kurobutaman Teriyaki”! It will be available at FamilyMart stores across Japan starting November 25, 2025.
“Teriyaki” is a sweet and savory flavor based on soy sauce and sugar, which has gained worldwide popularity in various dishes like hamburgers and pizzas. Let’s take a closer look at how this beloved taste has been fused with the “steamed bun,” a classic winter feature at Japanese convenience stores.
The Legendary Pork Bun That Sold Over 70 Million Units
The original “Gokuuma Kurobutaman” has been a flagship product for FamilyMart since its launch in 2019, captivating many fans with its exceptional taste. To date, it has sold a staggering total of over 70 million units. It’s so popular that some say one is sold every two seconds.
The secret to its popularity lies in its meticulous attention to detail and high quality. The filling uses 100% domestic black pork and onions, making up a generous 50% of the entire bun. This juicy filling is enveloped in a chewy and resilient dough. This exquisite balance has been highly praised, even winning the Grand Prix, the highest honor, at the “Japan Food Selection” in 2024, an award judged by food experts.
A Long-Awaited “Teriyaki” Flavor in Response to Fan Requests
This year, marking the seventh anniversary of its launch, FamilyMart conducted a survey asking fans, “What flavor would you like to try in the ‘Gokuuma Kurobutaman’?” The winner, “Curry,” was released in September as “Gokuuma Kurobutaman Curry” and was met with great success.
And now, as the second installment, comes the flavor that ranked second in the survey: “Teriyaki.” This is the realization of a flavor that many fans have been eagerly awaiting.
A Sophisticated “Adult Teriyaki” Flavor Packed with Quality
The “Gokuuma Kurobutaman Teriyaki” is not just any teriyaki flavor. It maintains the commitment to quality of the original “Gokuuma Kurobutaman” while incorporating further innovations.
Its most distinctive feature is the special teriyaki sauce hidden in the center of the bun. This sauce is made with 100% onions from Awaji Island, which are renowned in Japan for their exceptional sweetness and flavor. Furthermore, it uses carefully selected seasonings, such as premium soy sauce often found in high-end Japanese restaurants and “Kokonoe Sakura,” a historic brand of mirin (sweet cooking wine). This results in an elegant teriyaki sauce that enhances the natural sweetness and depth of the ingredients.
In addition to the sauce, the black pork and onion filling surrounding it is also seasoned with a teriyaki flavor. As a finishing touch, coarsely ground black pepper is added to cut through the sweetness, creating a sophisticated taste that is truly worthy of being called an “adult teriyaki” and keeps you coming back for another bite.
The chewy dough, the juicy teriyaki-flavored filling, and the rich sauce that melts from the center—the harmony created by this three-layered structure is nothing short of perfection.
