Right side or Left Side?

Tokyo escalator etiquette.
If you gotta time or no energy, use the left side of it and stand still. If you are in hurry or too much energy, use the right side to walk up. Don’t just stand on right side or try to walk up in left side. I never learned this but everyone knows. Also, be careful in osaka, the west side of Japan, it’s the opposite side. Do it right, and sink in.
