Japanese convenience store chain FamilyMart is launching another noteworthy new product. This time, it’s a pouch-packaged dish supervised by Masahiro Kasahara, the owner-chef of “Sanpi Ryoron,” a famous Japanese restaurant in Ebisu, Tokyo, known for being incredibly difficult to book.
Starting Tuesday, November 18, 2025, the “Chicken Meatballs with Egg Yolk-Style Sauce” will be available at approximately 16,400 FamilyMart stores nationwide in Japan. Priced at 397 yen (428 yen including tax), it’s an affordable opportunity to enjoy the taste of a renowned restaurant.
About the Famous Restaurant “Sanpi Ryoron” and Chef Masahiro Kasahara
“Sanpi Ryoron” is a restaurant constantly talked about among food connoisseurs, known for its creative Japanese cuisine. Owner-chef Masahiro Kasahara has earned high praise for his dishes that infuse traditional Japanese food with a modern sensibility, all under his motto of “Skill, Taste, and Playfulness.” Its popularity is so immense that securing a reservation is extremely difficult.
This is not the first collaboration between FamilyMart and Chef Kasahara. In the past, he has supervised products such as onigiri (rice balls), Eho-maki sushi rolls (which play a significant role in seasonal events), and the sauce for unaju (eel rice boxes), a well-known stamina meal for the summer, all of which have been very well-received.
The Appeal of the New “Chicken Meatballs with Egg Yolk-Style Sauce”
This new release is the first pouch-packaged dish supervised by Chef Kasahara to be featured in FamilyMart’s private brand, “FamiMaru KITCHEN.” It’s a take on “tori tsukune” (Japanese chicken meatballs), a popular dish in Japanese homes, prepared with the chef’s unique touch.
The greatest feature of this product is its combination of texture and flavor. The chicken meatballs include lotus root (renkon) for a delightful crunchy texture. When you break open a meatball, a rich, egg yolk-style sauce oozes out from the center. This recreates the classic pairing of tsukune and egg yolk, a staple combination often found in Japanese yakitori restaurants.
The meatballs are coated in a sweet and savory sauce with a perfect balance of sweetness and saltiness. This flavor makes it an ideal side dish for warm rice, a great addition to a bento box, or even a perfect “otsumami” (snacks served with alcohol), a unique part of Japanese culture.
