Isami BJJ Black Belt Competition


  • High quality Isami BJJ Black Belt handcrafted in Japan specifically for IBJJF competition.
  • This belt is based on our best selling F-450 black belt which has a soft core and is easy to tie.
  • The Isami Jiu-Jitsu Black Belt for Competition will "break" after only a few training sessions and the ends will fall into place beautifully.
  • There is a traditional red rank sleeve with white bars so you can add your degrees over the years.
  • Looking for embroidery and other customisations? Then upgrade to the Premium BJJ Black Belt.
100% cotton (Katsuragi and Sashiko Weave)
42mm wide with 9 stitch lines and white core
Estimated shrinkage (due to humidity and sweat) is about 7.5%
    • This belt is available in six sizes ranging from A0 all the way to A5.
    • Please note that the belt is made to spec but there can be some shrinkage due to humidity and sweat. We do not recommend washing the belt, but if you choose to do so you can expect avg. 7.5% shrinkage over time.
    • There will be two tags on the belt: the Isami Japanese Classic label on top, and the Made in Japan label right underneath.
    • It takes us approximately 10-15 work days to custom make your new belt exactly the way you want. 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 and that we'll custom make the belt exactly the way you want it!

    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.

    I have purchased 4 belts through ChokeSports. Everyone of them was of exceptional quality and the workmanship was incredible! The customer service and ease of placing my order was awesome.

    Ken G. Colorado, USA

    I'm always happy to open the package to discover another new obi belt. The quality is still the best, delivery time still there, and most important the service is number one. Very dedicated to the client.
