TOKYO (AP) — Toshifumi Suzuki, the Japanese businessman credited with creating the 7-Eleven convenience-chain global retail empire, has died. He was 93.

Suzuki, an honorary adviser at Seven & i Holdings, died on May 18 of heart failure at his Tokyo home, the company said on Monday.

Suzuki founded the Japanese unit that operates the seemingly ubiquitous 7-Eleven ‘conbini’ outlets, where busy people can hop in and grab sandwiches, rice balls, drinks, chips and other meals on-the-run; use ATMs; pay utility bills; and copy documents.
