差別的だ、っていうヨツベのコメントに対する回答・・・・

Yes i know: The men work in the garden in spring (which is hard work, which makes them sweat).
They sell those used tshirts in a vending machine to people from an urban area (-> tokyo)
so they can experience "the smell of spring" (since its an urban area they dont have that)
hey leaned this advertisement on Japan, since Japan is being know for having vending machines for used underwear.
Thats why they use a Japanese girl and an urban area like Tokyo.
And its a girl smelling the tshirts and not a guy because in real life its men buying those used underwear from girls,
so they just changed the roles. So nothing racist or sexist here.?

使用済みパンティーの販売って、海外でもそんなに有名なのか？
売ってんの見たことないけど・・・
