Do NOT Hold Doors open for others when you are in Japan

Yes you read that right! I am a native Indian and I personally hold a door open for anyone no matter if it’s a man or a woman or an elderly person. That's just basic manners, isn’t it?

I was shocked when my teacher told me that the Japanese normally don’t do it. It is not discourteous or being rude or something. It is just not in their culture!
So, don’t be surprised if you ever happen to walk through a crowded area through a door. Just watch out for the door not to slap right on your face :D
