What are these flowers for??
These flowers are set in line in front of a bar, called club, and set by many guests of the club only to a woman for celebrating a new member of the club.
Anyway, what is a club?? A club is a place for men to drink and talk with dressed and beautiful women in a decorated interior. Ginza, a district in Tokyo, has many luxury clubs and it costs more than 500USD just only to drink and talk with them at least, though you cannot understand why men pay for it!! Yes, the clubs are for rich people.
