From the reviews

As a former US Olympic judo coach, Master Koo is knowledgeable and a fantastic teacher. There are numerous classes for both children and adults. I appreciate the way he is able to motivate younger kids (like my daughter) who would otherwise have difficulty listening.

★★★★★ — Beck, Sep 2023

Master Koo was very good. My kid started Taekwondo with tiny tiger level and continuing after Black Belt 2. He encourages kids to participate in tournaments. Teaches self defense techniques, falling techniques in way kids gets attracted and shows interest. Lot more to tell.

★★★★★ — Raghav, May 2024

Wonderful taekwondo school with a warm and professional environment. Master Koo is patient, encouraging, and truly cares about each child’s progress. Since joining, my child has become more confident, focused, and disciplined.

Your first judo class at JS Martial Arts

Nervous about walking into a judo dojo for the first time? Almost everyone is, and good sensei expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, learning to fall safely (ukemi), then drilling a throw or two and some groundwork with a partner — not hard randori. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a judogi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many dojos lend a loaner judogi for a first class, so it's worth asking when you call. As you keep training you'll add your own judogi. Live randori eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the sensei. It gets easier fast — most people feel far more at home by their third class.

Judo is a contact sport. Ease in, tap early and often, listen to your sensei, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
