The former CEO of Sony, Kaz Hirai, will also be stepping down as the company's board chairman and departing the company.
Hirai first announced he would hand off the role of CEO in February of last year, but at the time said he would remain on as director and board chaiman when the new company structure took effect the following April. He has continued to hold those roles since, while the role of CEO passed to Kenichiro Yoshida.
Today, in a news release, Sony announced Hirai would also retire from the role of board chairman, to be replaced by director Shuzo Sumi.
