I've seen couples kiss each other on train. How one feels kissing in public depends on many kinds of factors.
In Japan, whether one lives in rural areas or not and how old one is would be two big factors.
I remember a actor said "During my living in the countryside, I thought joining hands a kind of sexual acts. So,when I came to Tokyo, I was confused with seeing couples joining hands in public."
I guess he couldn't accept kissing in public, much less.
How do you think about kissing in public?
