Now I wouldn't say that my Mii looks like me (I cant tell its been so long since ive seen it)but this is a bit of a silly way of looking for somebody
Its one of those "Only in Japan" things
its common for lifelike drawings of wanted folks to be issued but it looks like Kanagawa police decided to use the lifelike properties of the Mii making tool to create a "this man is wanted" image. This man is wanted for a hit and run - if you see him please report him to Kanagawa police immediately.
So if you see somebody that looks like that please report him
