There are several theories why the Japanese now using peace sign.
But most Japanese do not know why the peace sign.Since everyone is doing, to imitate them.
They do not think seriously,there is no negative meaning.
It's a action to become a smile,as such John Lennon and Jimi Hendrix.
Some sign of hand, there is a very bad case in culture outside of Japan.
However, many Japanese people do not know it.Careful with travel abroad guidebook would be rare.
The Japanese are not so much to represent a sign of emotion by hand.
You saw the Japanese is wrong, I want you to tell him gently.Because they do not have malicious intent.
