I think of searching for someone in Japan is a bit like putting up a poster of a lost cat or dog on a telephone pole. Many people will walk by and not even notice it. Some will take a quick glance at it and think , nothing I can help with. A cat or dog lover who lives in the same area/neighborhood may stop and read it and think , if I see it , I'll try to catch it and help return it to the owner. Now if you get super lucky , a really nice/helpful person may take the poster down and use it to drive or walk around , showing it to people and trying real hard to find the missing animal. But that type of person is probably pretty rare. There are so many things that make finding a person in Japan very difficult if not impossible unless you are willing to pay someone who is a pro at it and even that might not work. Our section here "Japan People Search" is a bit like the poster on the telephone pole ; there's that slight chance you might get lucky but there is no guarantee , sorry to say.
