"In the future we would like to sell one million hybrid vehicles a year," Cho said, without giving a time frame.
He was speaking at the launch in Tokyo of two new hybrid models of its Harrier and Kluger sport utility vehicles.
Cho said Toyota hoped to sell 300,000 hybrid vehicles globally either this year or next.
It was not clear what 12-month period he was referring to -- calendar or the April to March financial year.
