"Automatic Doors Don't Open For Him" I remember hearing this idiom which meant someone was so lowly, they were not even considered a person. I don't know the source, but remember it was referred to as a 'common Japanese idiom'. Unfortunately, I can't seem to find it or its origin online. Is this not really an idiom? What is its source?

This humor appeared in the TV drama "Legal High" (), first season, in the first episode. The guy in question is named Sugiura ().

It doesn't really mean that the guy is lowly, it just means that he's a person who doesn't make his presence felt at all, so even the automatic door doesn't recognize him. The exact explanation in Japanese would be .

It is not really an idiom. I have not heard of it often, besides the TV drama episode.

(*)BTW, it's a nice TV series and I'd recommend watching it, it's available by VOD.
