Escalator Manners (エスカレーターの片側空け - 片側あけ)
The traditional custom of standing on one side of station escalators (the left side in Tokyo, the right side in Osaka) to leave the other half clear for people walking up. Note: Walking on escalators is legally discouraged today for safety.
Originated during the post-war economic boom when busy salarymen rushed through stations to maximize productivity. The side choice is flipped due to cultural histories (Osaka historically following international standard).
In Tokyo, stand on the left and leave the right open. In Osaka, stand on the right and leave the left open. However, current official railway rules highly encourage standing still on both sides to prevent falling accidents.
