  • You can customize your BJJ black belt with beautiful embroideries, different rank bars and stitched degrees that do not fall off.
  • Your new BJJ black belt will be handmade to order in Japan: it takes 10-15 work days to prepare and then ship.

These are our most premium Brazilian Jiu-Jitsu black belts and arguably the best BJJ black belts money can buy. Over the past years ChokeSports and Isami have become the preferred black belt brand to some of the most respected BJJ competitors and instructors around the globe. Every single detail is made to perfection so you are sure to get the belt of your dreams. It takes so long to become a BJJ black belt that the least you can do is get yourself a one-of-a-kind belt from us.


  • All-time best selling soft core black belt that's especially popular with Jiu-Jitsu fighters.
  • We embroider the fabric first and then we make the F-450 belt. There will be no trail on the reverse side, but the belt stitch lines will be over the embroidery.
  • 42mm wide, 100% cotton (Katsuragi and Sashiko Weave), 9 stitch lines and white core. Estimated shrinkage (due to humidity and sweat): about 7.5%.


  • All-time best selling thick core black belt for all styles of martial arts.
  • This is the thickest and heaviest of all our belts: it has a premium finish and feels very sturdy around the waist.
  • 42mm wide, 100% cotton (Hachijo Weave), 9 stitch lines and white core. Estimated shrinkage (due to humidity and sweat): about 4.5%.


  • These belts are especially popular with bigger fighters/instructors who need a belt that will match their large frame.
  • F-745: 45mm wide, 100% cotton (Hachijo Weave), 12 stitch lines and black core.
  • F-747: 47mm wide, 100% cotton (Hachijo Weave), 15 stitch lines and black core.
  • Estimated shrinkage (due to humidity and sweat): about 5%.


  • This soft core belt ages differently than any other belt because it keeps its black color over the years.
  • The F-900 black belt is pre-made in Japan, so we add custom embroideries to the finished belt. The embroidery will be over the belt stitch lines but the reverse side will show a trail.
  • 45mm wide, Made of Tetron fabric (65% Polyester, 35% Rayon), 9 stitch lines. Estimated shrinkage (due to humidity and sweat): about 2.5%.

According to IBJJF regulations, the BJJ black belt must have a 10cm/4in rank bar on one end. We give you the option to choose what your rank bar will look like: the classic red with white bars on the ends, plain red or even plain white, as some top competitors have used lately in competition. You can also request embroidered degrees that will never fall off, unlike the usual sports tape stripes. We stitch white degrees on the red rank bar and black degrees on the white rank bar.

A0 255cm / 100in, A1 275cm / 108in, A2 295cm / 116in, A3 310cm / 122in, A4 325cm / 128in, A5 340cm / 134in + Custom Size (you pick the ideal belt length for your body type or taste). Please allow 2cm/0.8in margin of error due to humidity and shrinkage.

You can customize the Isami BJJ Black Belt Premium with beautiful embroideries and turn it into a unique item. We have a reputation for making the most beautiful belt embroideries and we guarantee you will be impressed.


  • It takes us approximately 2-3 weeks to custom make your new Isami BJJ Black Belt Premium exactly the way you want.
  • The whole process is handmade and we always have many orders waiting in line.
  • But don't worry, we will send you a completion estimate a few days after the order is placed and we guarantee the wait is very much worth it.
  • We will custom make the belt you've always dreamed of.


  • The Isami BJJ Black Belt Premium is custom made for you and therefore 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.

Great belt with great customisations

The belt is great quality. I purchased the softer material and in glad I did. After one training session it broke it nicely and ties tight without coming undone like all other belts I've had. Do check the belt messurements so you get the right fit and also this will make sure the embroidery shows without it being hidden in the knot. For example I normally wear a3 size belts but the a2 fit perfectly and shows the embroidery but it's not overly long. So measure your belt you currently have to get the best size. The embroidery is very well done and great quality. I ordered the gold thread and its not flakey at all so would chip or fade with use. The only negative thing is the red bar only has stitching on the edges not through it so it moves a bit but nothing major. I love this belt. Expensive including vat and customs charges but well worth it for the belt I'll have for the rest of my life.

Excellent service and product

I recently ordered two Isami BJJ Black Belts Premium with customization embroidery. The product itself is amazing. The belt is beautiful. What impressed me more was the excellent service by ChokeSports. Both the dates and all the details were respected and the shipping was fast and accurate. Job well done!

Really great customer service and quality

The belt was a gift which was well received and in really good time considering the order date. It’s been so easy to deal with choke sports and I’ve been updated at every step. Would definitely purchase again considering the customer service. The quality of the belt is really special, good stitching and customization is exactly as requested. He loved the thicker belt option which sits tied quite well and on first use great for belt choke. Classic gold embroidery looks very stylish. Thank you!

What Customers Are Saying About Chokesports

I've always had my eye on RVDDW and Isami brand gear but wasn't sure about how to order in the US. ChokeSports made the process extremely easy and the shipping was amazingly fast. Extreme recommend to anyone on the fence.
