Every Japanese person I met and became friendly with in Europe was consistently kind. However...

1. There is a very distinct difference between Koreans and Japanese people.
Koreans will say that even if it kills them, they will return to Korea.
But Japanese people
say they escaped Japan and will never, ever go back to Japan again.
2. Japanese people are all kind and gentle as individuals.
But as soon as they gather and form a group, their eyes change in a chilling way. From that point on, you hardly see the kind, gentle Japanese individual. They tend to feel more comfortable within a group rather than as an individual.
