Do you still remember, the Japanese supporter action picked up trash in the 2018 Russian Word Cup?. Unashamed and reluctant, the Japanese women took cigarette butts using their own hands and and then threw them into the trash.
It turns out that maintaining cleanliness is a habit that has been thought since childhood. It's no wonder that Japanese people feel uncomfortable when they see garbage scattered on the streets, including when they see garbage around them while visiting several locations of the 2018 Asian Games in Jakarta.
