Itoham moved to full ownership of Anzco late last year.
Misonou has been a director of the company since mid 2013.
As well as his Japan industry experience, he has worked in beef processing and feed-lotting in Australia and had six years in the pork industry in the United States.
Misonou is a long-time Itoham employee who became president of Yonekyu when Itoham merged with it a few years ago.
Itoham is the second biggest Japanese meat processing and marketing company and Yonekyu the seventh biggest.
Anzco believes Itoham Yonekyu is the world’s 10th biggest meat company.
