Almost every "Japan etiquette" list is written to frighten you. Thirty rules, each one presented as a trap, and the implication that a wrong move will cause offence.
It won't. Japan is used to visitors and nobody expects you to get it all right. What actually happens if you break a rule is quieter and more annoying than offence: things go slightly wrong, people are slightly uncomfortable, and nobody tells you why.
So here are the ones that genuinely matter, and the ones you can stop worrying about.
The ones that matter
Be quiet on trains. This is the big one. Tokyo carriages are near-silent even when packed — no phone calls, no speakerphone, conversation kept low. A loud group on a train is the most reliable way to be visibly foreign in an unwelcome way.
Don't eat or drink while walking. Food is eaten where it's bought — you'll see people standing beside the stall finishing a skewer before moving on. Related: there are almost no public bins, a legacy of the 1995 subway attack. Carry your rubbish until you find one, usually at a convenience store.
Take your shoes off when the floor changes. A raised step, a change of material, a row of slippers — that's the line. Temples, traditional restaurants, fitting rooms, and any home. If you see shoes lined up, yours join them.
Wash before you get in the bath. In an onsen or a neighbourhood sento you clean yourself completely, sitting on a stool, before entering the water. The bath is for soaking, not washing. Getting this wrong is one of the few things that genuinely bothers people.
Don't tip. Not a rule so much as a fact: there's no tipping culture and leaving cash causes confusion. Staff may follow you out to return it. The price shown is the price.
The ones people worry about too much
Chopstick rules. Two matter: don't stand them upright in rice, and don't pass food chopstick-to-chopstick. Both echo funeral rites. Everything else — resting them on the holder, which hand, how you hold them — nobody is watching.
Bowing. You are not expected to bow correctly. A small nod is warm and sufficient. Attempting a deep formal bow reads as slightly odd rather than respectful.
Slurping. Yes, it's fine with noodles. No, you don't have to. Nobody is grading you.
Business cards. Unless you're there for work, this doesn't apply to you.
The ones nobody mentions
These are the practical ones that catch travellers out more often than the famous rules.
You often pay at a machine, not a person. Many ramen and soba shops have a ticket machine by the door: choose, pay, hand the ticket over. Sitting down and waiting for a menu means waiting a long time.
Cash still exists. Tokyo is far more cashless than five years ago, but small bars, older shops and some shrines are cash-only. Carry some.
Escalators have a standing side, and it changes city to city. Stand left in Tokyo, right in Osaka. Watch what everyone else does.
Tattoos can still be a problem. Some onsen, sento, gyms and pools refuse entry with visible tattoos. It's loosening, and small cover patches are often enough, but check before you travel across town.
Queue properly. There are painted marks on train platforms and outside restaurants. They're used.
What to do when you get it wrong
Say sumimasen and correct it. That's the whole procedure. The word covers "excuse me", "sorry" and "thank you for noticing", and it's the most useful thing in the language.
Nobody will make a scene. The culture that makes these rules stick is the same one that makes it unthinkable to embarrass you in public — which is exactly why nobody will tell you, and why lists like this exist.
The fastest version of all of it is going somewhere with a person who lives here for a day. You learn more from watching one local order lunch than from thirty rules on a page.
