Judo Dojo Etiquette for Beginners

Why judo bows so much

Judo's founder, Jigoro Kano, built the art around a principle usually translated as "mutual welfare and benefit" — the idea that training only works if both partners are looking out for each other, since you're practicing techniques that could genuinely hurt someone. Bowing is the physical habit that keeps that principle in the room: it's a small, repeated reminder that the person across from you is a partner, not an opponent to be disrespected.

The bows you'll actually do

• Onto and off the mat — a standing bow toward the mat area, every single time you step on or off it.
• To the instructor — at the start and end of class, usually from a kneeling position (seiza) during the formal opening.
• To your partner — before and after every drill or randori round, regardless of how the exchange went.

Everyday manners that matter more than they seem

• Keep your gi clean and your nails short — you're in close contact with training partners, and long nails or a dirty gi aren't just a hygiene issue, they can actually cause injuries.
• Don't walk across the mat during someone else's match or drill — walk around if you need to cross.
• Address instructors as "sensei" (or your club's local equivalent) rather than by first name, unless told otherwise.
• Show up on time for the opening bow — arriving mid-warm-up and joining without acknowledging the class is one of the faster ways to stand out for the wrong reason.
• Thank a partner after randori, win or lose — the bow covers the formality, but a quick word of thanks is the norm in most clubs too.

For parents of younger judoka

Kids' classes are usually more relaxed about the finer points, but instructors do appreciate parents reinforcing the basics at home — bowing onto the mat, listening when the instructor is speaking, and not wandering off during class. It's less about formality for its own sake and more about building the habit of respect early, which makes every belt test afterward easier.
