when did selangor have a japanese mentri besar

i remember the name khir johari. but khir toyo, mohd khir toyo, is the mentri besar of selangor. is he japanese? definitely not. only bumis can be a mentri besar. but never heard of a malay name like toyo before. toyo is definitely japanese, or at least sounds like toyota. a name can be misleading. or is there a misprint?
