The mysterious escalator etiquette of Japan
The golden rule of escalator etiquette in the Tokyo area is that persons who ‘stand’ on the escalator are to stay on the left side while people who ‘walk’ the escalator stay on the right side. In the Osaka area it is the opposite. It is very mysterious!
Why, you ask? During a 1970 exposition in Osaka, it is speculated that the custom of moving on the left side was derived from Europe and America because of all the western visitors at the expo.
