Why aruki-sumaho is the pet peeve that won’t go away
Japan has spent over a decade running public-service campaigns, poster ads, and station announcements against aruki-sumaho (歩きスマホ — literally “walking smartphone”). The term is a household word. Rail operators and phone carriers have run joint campaigns under the slogan やめましょう、歩きスマホ。 (“let’s stop phone-walking”). And yet the Tokyo Fire Department still records dozens of ambulance transports a year from phone-walking accidents — collisions, falls from platforms, falls down stairs — the whole category.
The reason it stays a pet peeve is that Japanese public space runs on everyone-watches-everyone coordination. You don’t need a traffic cop at a station entrance because 200 commuters are already self-organizing around each other. An aruki-sumaho walker punches a hole in that system: unpredictable pace, unpredictable direction, zero eye contact. One person doing it forces everyone else to adjust.
The Yamato ordinance — symbolic, not punitive
In June 2020, the city of Yamato, Kanagawa Prefecture became the first municipality in Japan to pass an ordinance against aruki-sumaho, effective July 1, 2020. The rule says people operating a smartphone in an outdoor public place should be in a stopped state, not obstructing other pedestrians.
Important caveats for visitors:
- There are no fines. The ordinance is awareness-based, not punitive. Nowhere in Japan is phone-walking an actual offense you can be ticketed for.
- A few other cities have since followed — Adachi Ward (Tokyo) and Ikeda (Osaka) among them, also without penalties.
- It started from a real problem. A city count just before the ordinance found about 12% of pedestrians near Yamato’s main stations walking while using their phones. The ordinance aims to shift that through social pressure, not penalties.
So you won’t get arrested. But the cultural signal is extremely clear: stop walking if you want to look at the phone.
Escalator rules are shifting — stand, don’t walk
This one surprises returning visitors. Authorities are campaigning to end the old “stand on the left in Tokyo, right in Osaka, walk on the open side” convention, though many people still follow it:
- Saitama Prefecture passed the first “no-walking on escalators” ordinance in March 2021 (in force from October 2021). No penalties.
- Nagoya followed in October 2023, also without penalties. During campaigns, volunteers (the “Nagoyaka Tachidomari-tai”) ride escalators to model standing still.
- Japan’s Consumer Affairs Agency has publicly urged people not to walk on escalators.
- A FY2024 Japan Elevator Association survey found 90.2% of respondents agreed walking on escalators should stop.
Practical takeaway: don’t walk up or down an escalator in Japan, and don’t look at your phone while you’re on one. Hand on the rail, both feet planted, screen away.
The bump-apology cheat sheet
- Brush-past or light shoulder-bump: ‘sumimasen’ + small 15-degree head-bow. Two seconds. Done.
- Actually bumped them hard / knocked something loose: stop, pick up whatever dropped, ‘sumimasen’ + a slightly deeper bow, ‘daijōbu desu ka?’ (are you okay?).
- You caused a real injury: stop fully, offer help, and if needed wait for station staff or find a police box (kōban).
The thing Japanese social norms really don’t want from you is escalation — a long English apology, dramatic hand gestures, or a conversation about whose fault it was. Quick, sincere, move on. That’s the whole pattern.
