From the reviews

I can't say enough good things about this school! All of the instructors are professional and really care about the students. My kids have been taking classes here for over a year and I've seen a lot of improvement not just with karate but in their every day lives.

★★★★★ — Heather, Jan 2018

Really nice people and good times and fun memories to have. Making friends there was easy and I had an exciting time for years. Thank you for the greatest karate experience of a lifetime. Big thanks to all the staff for delivering cheer and joy. They take respect seriously and in a good way.

★★★★★ — Joe, Oct 2016

We had my son’s 5th birthday party at NJMAA (Randolph location) and I cant recommend it enough! Renshi and Sensai Kim were extremely helpful and accessible for any questions we had leading up to the event. They provided pizza for the kids, cake (we picked out the flavor and design and they ordered it) and party favors.

★★★★★ — Shari, Nov 2019

The staff was friendly and it is great to see our children disconnect from the xbox to do this 2x weekly.

New to Karate? Start at New Jersey Martial Arts Academy

New Jersey Martial Arts Academy comes up as a beginner-friendly dojo — noted on their own site. If you've never thrown a punch or set foot in a dojo, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and the sensei scales the intensity to you. Second, you won't be thrown into hard sparring — reputable dojos build fundamentals (stances, blocks, punches, and kicks) for weeks, and kumite (sparring) eases in gradually, with pads and control. Third, all levels and ages really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most dojos are happy to let you watch or try a class first, so reach out before you commit.

Your first Karate class at New Jersey Martial Arts Academy

Nervous about walking into a Karate dojo for the first time? Almost everyone is, and a good sensei expects beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic stances, blocks, punches, and kicks — not hard sparring. Step to the side whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot. What to bring: water, and a mouthguard if you have one — many dojos lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi and the belt your dojo awards you. Kumite (sparring) 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.

Karate is a contact sport. Ease in, train within your limits, listen to your instructors, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
