⭐⭐⭐⭐⭐ Daniel G. from England
"I was very excited to receive my black belt and I can honestly say it is everything I expected and more. The kanji is fantastic and the feel of the belt material is amazing. This belt will last for life. Thank you ChokeSports."

⭐⭐⭐⭐⭐ Ruslan M. from USA
"I purchased many other belts from other brands before and I was always disappointed. This is my third belt from ChokeSports. The belt was made to my specifications and was delivered before the actual estimated date. I love my belt!"

⭐⭐⭐⭐⭐ Shay D. from Israel
"I ordered 3 belts for me, my friend and my sensei. My first impression was 'this is what I call Japanese hand made'. Everything that I had asked for was just perfect - the thick core, the size and the embroidery letters. Feels and looks wonderful. Totally worth the money."

BELT MODEL: Which one is right for you?
➡️ F-450 has a broken-in feel and is easy to tie. When this belt starts to fray, the white inner core will show. This is our best selling soft black belt.
➡️ F-742 feels hard and sturdy around the waist. When this belt starts to fray, the black inner core will show.
➡️ F-700 is the thickest and heaviest of all our belts so it takes longer to "break" than other belts. When this belt starts to fray, the white inner core will show. This is our best selling stiff belt.

⏲️ It takes 20 work days to custom make your new belt, but we also offer a rushed service (10 work days) for urgent orders. The whole process is handmade and we always have many orders waiting in line. We will send you a completion estimate a few days after the order is placed so you know when it will ship.
✅ Because these belts are made to order and unique, they cannot be returned or exchanged. So please make sure to double check all the details before completing your order. Once we start working on the belt, no changes will be accepted. All sales are final.
🤩 We guarantee the wait is very much worth it: we'll custom make the belt exactly the way you want it!

BELT WIDTH: 42mm, 45mm, 50mm
Now you can choose how wide your Isami Karate Black Belt should be. The standard belt width is 42mm (1.65in) but we also make wider variations that are 45mm (1.80in) and 50mm (2.00in). They are especially popular with bigger fighters/instructors who need a belt that will match their large frame.

Our Isami Karate Black Belts feature integrated embroideries. This is the most premium method of embroidery and also the most resistant. We embroider the fabric first and then we make the belt. There will be no trail on the reverse side, but the belt stitch lines will be over the embroidery. The final product is unique and stunning!

Show your hard earned rank with stitched degrees that will never fall off, unlike the usual sports tape stripes. You can choose the color of your stripes to perfectly match your martial art and attitude.

Your new Isami Karate Black Belt will shrink naturally due to humidity and sweat. That's why we say in Japan that "the fabric is alive". Below you'll find our estimated shrinkage rates for each model. Please take this in consideration when selecting your optimal belt size...
F-450: 7.5%
F-742: 5%
F-700: 4.5%

In Japan it is uncommon to wash the obi martial arts belt. However many of our international customers like to wash their belts. We recommend hand washing (with hand soap) and hang drying in the shade. Please note that regular washing will accelerate the belt's aging process and might cause it to shrink further than estimated. It will still be functional and last for many years though.
