We have seen some crazy Japanese ads in our time - but this really is at the top of the pecking order.
But this is something special. It features a young woman being menaced by a couple of stalkers pretending to be birds.
Their cunning disguise? Some motorcycle helmets painted to look like birds' heads.
But what is it advertising? Well, your guess is as good as mine. I have heard that it is for some kind of house price comparison site, while others suggest it is for a natural, bird-based fertilizer for the tiny plant on her night stand. Apparently, the tagline is "The natural kiss for nature bliss".
Personally, I hope it is for the bird motorcycle helmets. Because if they are selling, I am buying.
