📅 Custom belts are handmade to order rather than pulled from stock. The estimated timeline is listed in the Pre-Order box directly under the Add to Cart button. When capacity allows, a rush upgrade is available at checkout to shorten that window. This upgrade must be selected when placing the order and cannot be added afterward. This lead time ensures our craftsmen have sufficient time to create your personalized belt with the attention to detail it deserves. Thanks for your understanding.
📧 Pre-order now and you'll receive the following email updates:
a provisional shipping estimate a few days after placing the order.
the precise shipping estimate when the item has moved through various stages of production.
door-to-door tracking once the order has shipped.
✅ 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.

Description
The Ultimate Coral Belt — Reserved for Masters
TL;DR: The Isami Red & Black Belt, also known as the coral belt, represents one of the highest levels of recognition in BJJ and Judo. Each belt is custom made in Japan by Isami and crafted individually for the practitioner. This is the same red and black belt we produce for Renzo Gracie, Vinicius “Draculino” Magalhães, Roberto Gordo, Wellington “Megaton” Dias, and other legendary masters. If you’ve earned it, this is the belt that honors it. Order yours through ChokeSports—the official international distributor and specialists in Isami.
Custom Made in Japan — No Shortcuts
True Custom Construction: Every coral belt is made to order in Japan, not pulled from stock.
Integrated Embroidery: Names and kanji are embroidered into the fabric before assembly.
Correct Proportions: Signature black panels measure 8 in / 21 cm on each end.
This belt is built using traditional Katsuragi Ayaji cotton and assembled entirely in Japan by Isami’s master belt makers. Unlike surface embroidery, integrated embroidery becomes part of the fabric itself, ensuring long-term durability and a clean reverse side. The belt ages naturally over time, developing character without losing structure or clarity. This is the construction standard Isami follows for belts made for elite masters worldwide.
A Belt Earned by Rank, Not Purchased by Trend
BJJ Coral Belt: Traditionally awarded at 7th degree and above.
Judo Coral Belt: Recognized as a symbol of lifetime contribution.
IBJJF-Ready Details: Built to correct black and red belt specifications.
This red black belt is not a fashion item or display piece. It exists to mark decades of contribution, teaching, and mastery. Whether used in BJJ or Judo, the red and black belt carries cultural weight and technical accuracy. ChokeSports specializes in these belts and works directly with Isami Japan to ensure every detail is correct. We are the official international distributor for Isami, and we treat master belts with the respect they deserve.
BELT MODEL: Which one is right for you?
➡️ SOFT BELTS are lightweight and have a broken-in feel. They are made of 100% cotton with 9 stitch lines and measure 1.65 in / 42 mm wide. ➡️ STIFF BELTS are heavier and feel sturdy around your waist, taking longer to break in than a soft belt. They are made of 100% cotton with 13 stitch lines and measure 1.65 in / 42 mm wide.
INTEGRATED EMBROIDERY
Our custom made 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.
RANK BAR AND DEGREES
Here at ChokeSports we can add rank bar and degrees to Side B of your belt. You get to choose what your rank bar will look like, or simply order the belt without any rank bar. According to IBJJF regulations, the BJJ Red Black Belt must have a 6 in / 15 cm white rank bar with silver borders and red degrees.
🚿 BELT WASHING INSTRUCTIONS
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.

Customer Reviews
Overall rating: 4.8 / 5 from 23 reviews.
I discovered that finding a 7th degree red and black Martial arts belt was difficult. My instructor sent me a link to this company. I was able to find what I needed and also had it personalized. Very good quality. Well worth it.
Store owner replied:
Hello Kenneth,
Thank you for the wonderful review of your Isami Red Black Belt! It's great to hear your instructor pointed you our way, and that we had exactly what you needed for a 7th degree belt, that's not always easy to track down.
We're glad the personalization and overall quality lived up to expectations, that's the kind of genuine Japanese craftsmanship we aim for with every belt, especially one that represents this much rank and experience.
If you have a moment, we'd love to see a photo of your new belt, whether it's a close-up of the embroidery or a shot of you wearing it. Feel free to share it here or post on social media with #chokesports!
Best regards,
The ChokeSports Team

Store owner replied:
Hello John. Thanks for the feedback. We are sorry to hear that you don't like the thickness of your new belt. I checked the order details and saw that you selected the soft belt variation. If you wanted a thick belt you should have picked our stiff belt variation and we'd have gladly made it for you!In the product page you'll find side by side comparisons between both models as well as the following explanation...SOFT BELTS are lightweight and have a "broken-in" feel. They are made of 100% cotton with 9 stitch lines and measure 42mm 1.65in wide.STIFF BELTS are heavier and feel sturdy around your waist, taking longer to "break" than a soft belt. Made of 100% cotton with 13 stitch lines.All the best from the ChokeSports.com team!
Nice belt. My experience was great and was kept updated though the process of getting this custom belt. I will be happy to order from Choke sports in the future. I recommend this product.

It means a lot to us that you selected our company for this very special moment. The belt and the certificate look great together, by the way.All the best from your friends at ChokeSports.com!
A Master's belt. The fine print needs to be echoed twice on how long before starting working on belt to factor into total time of delivery coming from overseas instead of in the US
Store owner replied:
Hello Gregory. Thanks for the feedback. We make it clear in the product page that these belts are handmade to order in Japan, which usually takes 20 work days to prepare and then ship.
