The annual meeting of Avex Group was notable in three ways: it was held on a Sunday, it defied Japan’s yakuza gangsters, and it ended in a pop concert.

About 9,000 shareholders in Avex, one of Japan’s largest music companies, went to the Saitama Super Arena in the suburbs north of Tokyo to question their board of directors and then follow it up with a free concert given by some of the group’s artists.
