FamilyMart, one of Japan’s leading convenience stores (known locally as Konbini), is launching a major project as it approaches its 45th anniversary. In collaboration with the legendary rice ball specialty shop “Onigiri Bongo” located in Otsuka, Tokyo, the company will host “Parent-Child Omusubi Workshops” at five locations across Japan to promote community exchange. Starting with an event in Fukushima Prefecture on March 15, 2026, this special food education initiative will expand to various regions throughout the country.

Preserving Japanese Food Culture: The Collaboration Between “Onigiri Bongo” and Konbini
“Onigiri Bongo” is a world-renowned specialty shop for onigiri (Japanese rice balls, a true soul food), famous for the long queues that form outside its doors every day in Tokyo. The owner, Yumiko Ukon, has a deep-seated passion for passing down the techniques of making traditional omusubi to the next generation. FamilyMart, aiming to contribute to local communities, resonated with this vision, leading to the launch of this project in 2024.
Previous events have received high praise from participating families, with many expressing excitement at learning professional techniques firsthand. In 2026, this initiative will be significantly strengthened. While past events were limited in location, it has been decided to hold them sequentially in five regions across Japan to bring this experience to a wider audience.
The Master’s Secret: “Assembling” Instead of Squeezing for a Fluffy Texture
In these workshops, owner Yumiko Ukon serves as the instructor herself. Participants not only learn about the history and culture of onigiri but also receive direct guidance on the secrets to creating the signature “fluffy texture” that melts in the mouth.
The “Bongo” technique is unique because it focuses on gently “assembling” the rice rather than squeezing it tightly. Witnessing and experiencing this craftsmanship up close is sure to be a lifelong memory for the children involved.

On the day of the event, a variety of traditional Japanese ingredients will be provided. Participants can enjoy eating their “masterpiece” on the spot. This serves as a highly valuable “food education” experience, teaching children the joy of preparing food with their own hands.

The 2026 nationwide tour begins on March 15 at the “FamilyMart Koriyama Nakamachi Store” in Koriyama City, Fukushima Prefecture. The tour is scheduled to visit various regions across Japan through November. Each venue will host approximately 20 pairs of parents and children in a warm, welcoming atmosphere.

Accelerating Community Contribution with the 45th Anniversary Slogan “Ichiban Challenge”
FamilyMart will celebrate its 45th anniversary in September 2026. To mark this milestone, the company has introduced a new slogan: “Your ‘Ichiban’ (Number One) Challenge: Creating Many of Your Favorites.” This represents a commitment to becoming the most familiar and preferred presence for every customer.

These workshops are a concrete example of the “Being Loved by the Community” pillar of this slogan. FamilyMart aims to be more than just a place to buy goods; it strives to create “community hubs” by utilizing its in-store dining areas (eat-in spaces).

The Power of Omusubi to “Tie Hearts Together”
Yumiko Ukon, owner of “Onigiri Bongo,” often says, “Omusubi is something that ties heart to heart.” In an age where mass-produced, machine-made rice balls are the norm, it is important to understand the warmth of making something with love for someone else. Through this activity, it is hoped that family bonds will be further strengthened.
Beyond the Convenience Store: Becoming an “Indispensable Place”
FamilyMart is currently evolving from a simple convenience store into essential social infrastructure. The “Parent-Child Omusubi Workshop,” where participants learn the skills of a long-established master, is a symbolic event of this evolution. FamilyMart’s challenge toward its 45th anniversary will continue to bring smiles to faces all across Japan.
