Japan’s Unspoken Rules

Learn the unwritten rules that matter on trains, in public places, and in everyday life in Japan.

Japan has many rules that are not laws, but are treated as obvious social expectations. If you break them without realizing it, people may react coldly even if nobody says anything directly.

Rules on trains and at stations

• Phone calls on trains are generally not allowed. If your phone rings, silence it quickly and reply by message instead.
• Music and videos should be listened to with headphones. Playing audio through your speaker is considered rude.
• In crowded trains, hold your backpack in front of you or place it on the rack.
• On the platform, line up at the marked boarding position and wait until everyone gets off before getting on.
• Priority seats are for elderly passengers, pregnant people, and people with disabilities. Even if they are empty, many people avoid sitting there unless necessary.
• On escalators, one side is usually kept open: people stand on the left in Tokyo and on the right in Osaka.

General public-space rules

Noise and voices:

• The basic expectation is to stay quiet in public.
• Loud conversations are not appreciated, even in restaurants.
• Children crying cannot always be helped, but parents are still expected to show consideration to people around them.

Eating while walking:

• In general, eating while walking in public is not viewed positively.
• Festivals and food stalls are exceptions.
• Eating on a bench in front of a convenience store is usually fine.

Lining up:

• Japan has a strong queuing culture.
• People line up neatly at banks, government offices, supermarkets, and many other places.
• Cutting in line causes strong resentment.

Manners in shops

• Staff often say “irasshaimase” when you enter and “arigatou gozaimashita” when you leave. You do not need to reply, though some people give a small nod.
• Do not open products on your own.
• Ask before trying something on. In many stores it is allowed, but checking first is common.
• Using your smartphone while paying has become a small etiquette issue. It is better to put your phone away during checkout.

Time expectations

• Being late for an appointment is seen as very rude.
• In business settings, arriving 5 to 10 minutes early is standard.
• Even if you contact someone to say you will be “a little late,” the delay itself still calls for an apology.
