Original stickers, what are these?
 

Hi, my dad has had his Subaru for a few years now, the car needs work done so we haven't been using it much recently. But today I noticed these original Japanese stickers? He said they've been there since it was made? Can any one tell me what these are, if at all they mean anything.

Thank you! :)

Red me is a vehicle inspection sticker.
Green one is Road Tax.
No idea on the last one.
