Well, the main characteristics of " 草食系男子/soushokukei-danshi” are as follows
- They prefer staying home rather than going out in their free time.
- They are (relatively) sensitive and kind.
- They don't actively/aggressively try to find their girlfriends and date.
- When a man is asked by a woman to go shopping or to go to dinner etc, he will accept her offer, and will accompany her on the outing, but this rarely leads to them dating each other.
- When they spend the night with a woman who is just a friend, and sleep in the same room, nothing even happens between them.
It seems that Japanese men in their 20s are no longer able to serve as the driving force for the expansion of domestic demand.
