Found at Tokyu Hands in Ikebukuro a couple weeks ago:
But even if it is, do you know what a douche is? And I don't mean the shortened version of the slang "douche bag". Do you want this in your home, on your counter? I like the antique appearance of the container, and several of the other containers around it had other logos and printing from other old products that looked pretty cool. But, a douche... And yes, the literal translation from French to English of douche is shower - but does anyone say "I'm going to go douche" and mean the kind which involves cleaning the entire body?
In France, perhaps this is okay. But I'm not so sure this is anything authentically French. Do you use cotton balls to comfortably shower yourself?
