Japan ... underwear-obsessive-perverts island

For those of you who live in Japan, you may agree with me that Japanese people in general dont hesitate to ask some personal questions to people they just met. Like, "Do you have a gf/bf? What's your type?" or "How much do you make a month?!" I know its considered to be rude in the west society.

But yesterday, i experienced a total new awkward-situation when i was having my hair cut and being asked by the hairdresser dude "What kind of underwear do you wear? How much they cost?"
I shit you not, thats what he asked me, a stranger he just met for 15 minutes. I know that it's shamefully well-known by foreigners that Japanese men are panty-loving-perverts of the planet, but i have no idea if it's that bad.

To my loyal readers who dont live in this island, this is exactly the shit i was talking about. The "joy" you may not get from living in other countries.
