FamilyMart Co., Ltd. will celebrate its 45th anniversary in September 2026. As part of its 'Best Taste' initiative, the company is collaborating with the specialty rice ball shop 'Bongo' (Location: Toshima-ku, Tokyo; Owner: Yumiko Ukon) to release two new rice ball products: 'Bongo Supervised Large Rice Ball - Minced Tuna and Raw Cod Roe' (323 JPY, 348 JPY incl. tax) and 'Bongo Supervised Large Rice Ball - Fried Chicken and Mayonnaise' (332 JPY, 358 JPY incl. tax). These will be available at approximately 16,400 FamilyMart stores nationwide starting June 9, 2026.

The 'Bongo Supervised Hand-rolled Rice Ball' series, launched in March 2025, has received strong customer support. Combined with the 'Large Rice Ball' series (August 2025) and the 'Gochi-musubi' series (November 2025), the total sales have surpassed 15 million units.

These new 'Large Rice Balls' are 1.5 times the size of standard hand-rolled rice balls.
