Judo Member's Guide

Welcome to the world of Kodokan Judo!

History of Judo
Judo, meaning “gentle way,’ is a popular and venerable Japanese martial art that has spread in popularity so far as to become an Olympic sport. The main objective of the martial art is to pin an
opponent to the ground, or force a submission by applying a chokehold or joint lock. The three main
techniques involved in modern Judo are throwing techniques or nagewaza, or katame-waza which are techniques in groundwork. Choking submissions (shime-waza) are only allowed from 13 years and older and joint locks (kansetsu-waza) are only allowed in 16 years and older. 

Judo Gi (Uniforms):

1. Our facility has a few rental Gi that you may use, if available.  You may utilize a rental Gi until you purchase your own. 

2.  When you are ready to purchase a Judo Gi, we can have you sized up and will order a team Judo Gi.  We have different styles and prices.
