He could not be reached for comment. Suzuki quit in a surprise move after narrowly failing to garner enough board votes to remove Isaka as the head of Seven & i's profitable convenience store unit Seven-Eleven Japan. Isaka, a veteran executive at Seven-Eleven Japan, has been credited with driving the convenience store chain's growth but Suzuki contended that Isaka had not lived up to expectations. The parent company then named Isaka as president to succeed Suzuki. New management will take over after the shareholders' meeting. INVESTOR CONCERNS Some analysts, though, have questioned any potential advisory role for Suzuki. In a report last month, Deutsche Bank said an advisory role or honorary position "may raise investor concern about the transition to the next generation of management". Isaka played down such concerns. "We will be able to consult him when we need to seek advice but at the end of the day his position is just an advisory one," he said.
