Should you bow toward the front of the room even if you're only watching a class?

Yes — Yes — the bow is to the dōjō itself, not to a performance. Visitors observing (kengaku / 見学) bow on the way in and out, take their shoes off, and sit properly rather than lounging against the wall.

Can you keep your wedding ring and watch on during a trial class?

No — No. Rings, watches, bracelets, necklaces and piercings all come off before you step on the mat — they injure both you and your partner during grips and throws. Nails short, hair tied back, bare feet.

If you arrive after class has started, should you walk straight onto the mat and join the back row?

No — Wait at the edge of the mat, bow, and wait for the instructor to invite you in. Crossing the mat mid-class without acknowledgement cuts through a session that has a formal beginning and end.

Dojo Etiquette: How to Walk Into a Japanese Martial Arts Class Without Getting It Wrong

Judo, karate, kendo, aikido — a trial class or even just watching from the side is one of the best experiences a visitor can book. But a dōjō is a room with its own grammar: you bow into it, you strip off everything metal, and you never call the teacher by name. Here's what to do from the doorway onward.

Walking in and out like it's a gym

Strolling onto the mat without bowing, and leaving the same way

A dōjō (道場) isn't a rented sports hall — it's treated as a place with a front. That front, the shōmen (正面), often holds a kamidana (神棚 / small Shinto shelf), a scroll, or a portrait of the art's founder. Walking in with your shoes on, wandering onto the mat mid-conversation, and slipping out at the end without a word reads as genuinely disrespectful, in the same way as putting your feet on someone's family altar would. Visitors do it constantly because nothing is signposted in English.

Bow at the door, bow at the mat, bow on the way out

Shoes off at the entrance, lined up neatly with the toes pointing back toward the door. Then a standing bow (rei / 礼) toward the shōmen (正面) when you step into the room, and again at the edge of the mat before you set foot on it. Do the same in reverse when you leave — bow off the mat, bow at the door. Nobody expects perfect form; the visible act of stopping and bowing is the whole point. If you're only there to watch (kengaku / 見学), you still bow in, and you still sit properly rather than sprawling against the wall. 🙇

Training in your everyday accessories

Keeping the watch, ring, earrings, and long nails on

This one isn't ceremony, it's the rule that gets enforced hardest. Rings tear skin during grips, a watch or bracelet gouges a partner in a throw, earrings and piercings catch on a sleeve, and untrimmed toenails and fingernails slice people open on the mat. Instructors routinely stop a class to send someone off to deal with it, and turning up with a full set of jewellery marks you instantly as someone who hasn't checked what they were walking into. Bare feet are also assumed on tatami or a wooden floor — socks slide, and shoes never go on the mat.

Strip everything off, cut your nails, tie your hair back

Before you leave the changing room: rings, watch, bracelets, necklace, earrings and any other piercing all come off — leave them in your bag, not on the mat edge. Cut fingernails and toenails short the night before. Tie long hair back with a soft band, no hard clips. Train barefoot unless you're told otherwise, and keep your feet clean — you walk to the mat, so many dōjō have sandals for the trip from the changing room. If the school lends you a gi (道着), treat it as borrowed clothing: wear it, then hand it back folded. 💍

Talking to people the way you would at home

Calling the instructor by their first name — and coaching your partner

Two habits that travel badly. Using the teacher's given name, or even 'Tanaka-san', is off: the instructor is addressed as sensei (先生), full stop. And in a class where everyone is finding their level, visitors with a bit of experience elsewhere often start correcting the person opposite them mid-drill. In a Japanese dōjō, teaching flows downward — from the sensei, and from senior students to junior ones. A newcomer explaining technique to a partner comes across as taking over the class.

Sensei, senpai, and 'onegaishimasu'

Call the instructor **sensei** (先生) — either alone or after their surname, as in 'Tanaka-sensei'. Senior students can be addressed as senpai (先輩) if you want to be careful, though many will just tell you their name. Learn two phrases and you're covered for the whole class: **onegaishimasu (お願いします)** — 'please, let's train' — said with a bow to each new partner, and **arigatō gozaimashita (ありがとうございました)** afterwards. When corrected, answer 'hai' (はい), adjust, and keep going. Questions are welcome; unsolicited coaching isn't. 🙏

Coming and going on your own schedule

Wandering in late, ducking off the mat, filming whatever you like

Class has a shape: a formal opening bow, drills, a formal closing bow. Walking in halfway through and joining the back row, stepping off the mat for water or your phone whenever you feel like it, or leaning against the wall with your legs stretched out toward the shōmen all break it. Filming is its own issue — visitors often set a phone recording from the corner without asking, and plenty of dōjō don't allow photography of members at all.

Wait at the edge, ask before you step off, ask before you film

If you're late, don't cross the mat. Kneel or stand quietly at the edge, bow, and wait until the instructor gestures you in — every dōjō has a version of this and they'll show you. Need to leave the mat mid-class for water, the restroom, or because you're struggling? Catch the instructor's eye and ask; slipping away unannounced is what's rude, not the leaving. When sitting out, use seiza (正座 / kneeling) or cross-legged if your knees can't take it, never legs stretched toward the front. And ask before you photograph or film anything — including yourself. 📵

A dōjō is a room with a front

Most visitors book a trial class expecting a fitness studio and walk into something closer to a small hall. The giveaway is the shōmen (正面) — the designated front of the room, often marked by a kamidana (神棚), a hanging scroll, or a photograph of the founder of the art. Everything in the space is oriented toward it: you bow toward it, you don’t turn your back on it casually, and you don’t sit with your legs stretched out in its direction.

Once you see the room that way, most of the etiquette stops feeling arbitrary. Rei (礼) — the bow — is simply the punctuation between one part of the session and the next.

The bows you’ll actually use

There are two forms — ritsurei (立礼), standing, and zarei (座礼), from kneeling — and four moments that cover nearly everything:

Entering and leaving the room — a standing bow toward the shōmen.
Stepping onto and off the mat — a bow at the edge, every time, including mid-class trips.
To the instructor — at the formal opening and closing of the session, usually from seiza.
To each partner — with onegaishimasu (お願いします) before, arigatō gozaimashita (ありがとうございました) after.

Your form will be wrong at first. That genuinely does not matter. Stopping to do it at all is what registers.

What comes off before you step on

Bare feet on tatami or wood. Shoes stay at the entrance; many schools keep sandals for walking from the changing room to the mat so your soles stay clean. Rings, watches, bracelets, necklaces, earrings and other piercings all go in your bag — this is a safety rule and instructors enforce it. Nails short, long hair tied back with something soft.

If you’re borrowing a gi (道着), wear the white belt you’re given. Turning up in a coloured belt earned in another country, or another art, is a conversation to have with the instructor first, not a decision to make yourself.

Who talks, and who doesn’t

The instructor is sensei (先生), never their given name. Senior students are senpai (先輩). Instruction moves downward through that order, which means a visitor’s job in a drill is to try, be corrected, and try again — not to correct their partner, however well-intentioned. Answer corrections with hai (はい) and adjust. Save your questions for the instructor, who will almost always be delighted to get one.

Watching, filming, and paying

Observation (kengaku / 見学) is normally welcome and often free, but it isn’t spectating: shoes off, bow in, sit properly, phone away. Ask before photographing or filming anyone, including yourself — some dōjō prohibit it entirely, and a member who didn’t consent ending up on someone’s feed is exactly the reason. Trial fees (taiken-ryō / 体験料) are frequently cash only, so bring some.

Quick check

Three questions to make sure you’ll get through the doorway, the mat edge, and the introductions cleanly.

Q1 Should you bow toward the front of the room even if you're only watching a class?
Q2 Can you keep your wedding ring and watch on during a trial class?
Q3 If you arrive after class has started, should you walk straight onto the mat and join the back row?
