I knew from my previous trip to Japan that you stand on the left side of the escalator, leaving the right side free for people who want to walk up. Except for Osaka, in which the standing and walking sides are flipped, which leads to rousing games of Spot the Osakan in Tokyo Station and elsewhere.
I also engage in another game when on the escalator, this one titled I’m Not With Those Asshole Gaijin Blocking The Entire Escalator.
Something I hadn’t noticed about Japanese escalator etiquette on my previous trip is one person = one stair. I have only seen one Japanese (I assume) person standing with one foot on the step in front of them, which is common in the USA,
