The Tip for taking an escalator in Japan.

When you take an escalator in Japan, you might notice that people around you stand on the one side of the steps so that others who are in a rush can walk up on the other side of the escalator. I wish I could tell you whether you should keep on the right or left but actually it depends on what city you're visiting. Generally speaking, in Tokyo you should keep left but in Osaka you should keep right instead. This manners is not written anywhere so you just have to find it out by yourself otherwise you will make a long que of grumpy people behind you waiting for you to get out of their ways.
