Just adding as french we normally don't spoil Moët et Chandon spreading all this good stuff on people like this
In the other hand, as I like Nihonshû very well, and as sake is expensive in France, I don't spoil it too
So in either case I would be skeptical after all, I know a bit yakusa's stories (even if I don't like Fukasaku's movies...) but the fact to spoil good things is strange for me...
