Keep to the left when standing on the escalators
You're expected to keep to the left when you are standing on the escalators. And to the right when you are climbing.
I say this because I am not good at it when I am in Osaka, where people do the opposite: to the right when standing, to the left when climbing. I end up finding myself standing on the left, with people passing by... Which makes me really uncomfortable...
