Who taught these Japanese people that kissing on the lips as a greetings is normal for foreigners????
"Kissing quickly on the lips with the mouth closed is a common greeting in some places of Western culture such as South Africa."
this is on wikipedia, but it has no sources. While I agree with you that this whole "kissing on the lips is common" is total bullshit, I see that apparently not only japanese people think this is a western thing to do (the person that wrote this agree with them, and maybe they're not japanese). I would love to see someone from South Africa answering my answer, for us to know if this is true there.
I'm sorry but back off girl
