エスカレーターの立ち位置、関東は左側、関西は右側って違うんだよ。
エスカレーターのたちいち、かんとうはひだりがわ、かんさいはみぎがわってちがうんだよ。
Where you stand on escalators differs—Kanto stands on the left, Kansai on the right.

Really? Has it always been that way?
Gesture & etiquette
If at a station with escalator, mime standing first on left side, then on right, with playful exaggeration. Mention modern safety guidance: '最近は『立ち止まって乗りましょう』運動もあるよ'. Friendly trivia tone.
Iconic East-West cultural difference. Kanto (Tokyo): stand left, walk on right. Kansai (Osaka): stand right, walk on left. The Osaka 'right-side' tradition is said to date from 1970 Osaka Expo when officials promoted right-stand for international visitors. Recently, safety campaigns urge 'don't walk on escalators at all'—both sides should stand.
