TOKYO : Japan risks reputational damage if it were to block a $47 billion foreign bid for retailer Seven & i Holdings on economic security grounds, the head of a government-backed fund said. Japan Investment Company (JIC) head Keisuke Yokoo also told Reuters in an interview the fund wants to help drive consolidation among chip-materials companies and is focused on improving performance at JSR, which it took private last year in a $6 billion buyout. JIC is not involved in the Seven & i deal,
