This man is carrying a huge bouquet on the train.
That's actually something you almost never see in Tokyo.
One of the most embarrassing places for Japanese men to go is a florist according to some survey.
(Unfortunately, I forgot what else was on the list. )
In the West, it is common for men to give flowers to women. And that is one thing you cannot expect in Japan. Women here buy flowers themselves.
So, if you are a man, and want to attract Japanese women, please buy them flowers. Trust me, it works!
Wondering why this Japanese man is carrying flowers? Probably your guess is correct!
