Toshifumi Suzuki, the founder of Seven-Eleven Japan and former chairman of Seven & i Holdings, died of heart failure in Japan on May 18, 2026.

Suzuki's leadership transformed the Japanese retail landscape by establishing the modern "konbini" system. His influence shaped how millions of people access food and services daily through a highly efficient network of urban stores.

Suzuki was 93 [1] at the time of his death. He is credited with scaling the brand across the country, overseeing the growth of more than 20,000 stores in Japan [2]. His strategy focused on meticulous inventory management and the integration of fresh food, which set the industry standard for convenience stores globally.

As the former chairman of Seven & i Holdings, Suzuki managed the parent company that controls the brand's international reach. His tenure saw the transition of Seven-Eleven from a foreign concept into a dominant Japanese cultural staple.

Family and company representatives said the cause of death was heart failure [1], [2]. The loss of the founder marks the end of an era for one of the most successful retail expansions in Asian history, a legacy built on precision and rapid scaling.
