Are there really vending machines for underwear in Japan??:D?

If you mean used high school girl panties, no. But you maybe able to find the disposable kind that people use once & then throw away. They're made of a paper material

Haha, well, I have to say yes, there are vending machines for underwear- but i don't know if you mean underwear as in new, unused ones or ones that pathetic men think girls actually wore buy? I have seen both but recently, the Japanese government banned the those Japanese vending machine owners to sell used schoolgirl underwear. I don't think they're all gone though ;) lol

If you search for the entire Japan, you may find it. But you can't find it so easily. I have never seen one.

not any more. They were removed as the police said that thee was no way to control the authenticity of the item, I am assuming he means school girl underpants
