Ritsu-rei

The "Ritsu-rei" (Standing bow) is a bow performed from a standing posture. In judo, the phrase "Rei ni hajimari, rei ni owaru" (Beginning and ending with a bow of respect) highlights the importance of respect, expressed through dojo bows before and after practice sessions or contests.
To perform a Ritsu-rei, stand naturally on your heels with a straight back, then bend your upper body forward by about 30 degrees, lowering your fingers to the height of your kneecaps. Before a contest, contestants face each other at the start lines and bow. After the contest, they return to the start lines, wait for the decision, step back, and bow again.
