Why one city flips the whole convention
Japanese stations move huge crowds every day, often through tight corridors. The one-side-standing, one-side-walking split is a habit, not an official rule — and it isn’t even efficient: a Hitachi study found it moves about 23% fewer people than standing on both sides.
The part that catches visitors: that consensus flips in Osaka. Tokyo and most other regions — stand-left. Osaka and much of the Kansai area (including Kobe) — stand-right. Kyoto is mixed. No sign tells you which side to use. You’re expected to glance at the people ahead of you and match. Locals tend to notice a mismatch quickly.
Tokyo = stand left. Osaka = stand right (like London). When in doubt, watch two seconds and copy.
A few “nice to know” extras
- The official rule is to stand still — Rail companies ask everyone to stand on both sides and not walk, and Saitama Prefecture (since 2021) and Nagoya (since 2023) have made it a local ordinance, with no penalty. In practice the one-side habit persists. Standing still is always within the rules; what annoys people is blocking the side others are walking on.
- Midosuji and Hankyu Umeda — Hankyu started asking riders at Umeda to keep the left side open back in 1967. If you’re transferring at Umeda, you’ll hit both. Stand right, walk left, don’t overthink it.
- Airport escalators can be messier — at Narita, Haneda, or Kansai International, many riders have just arrived from abroad, so the convention is often less consistent. It’s the beginner tutorial happening in the same building as arrivals.
- Moving walkways often follow the same logic — On flat walkways in airport terminals and underground passages, many people keep to one side the same way. If in doubt, copy the people ahead.
