📅 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.

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
Isami Green Belt: The Rank Where Young Practitioners Prove Themselves
ChokeSports.com is the official international distributor of Isami belts, and this martial arts green belt marks real, visible progress for the practitioners who wear it. Whether you're closing in on your BJJ green belt, your Karate green belt, or your Judo green belt, this is the belt that carries you there. Every belt is one-of-a-kind and made in Japan.
Three Firmness Models, Built for How You Actually Train
Choose your fit across three models, F-350, F-400, and F-700, from Slim & Soft to Thick & Stiff
Match your body type and grip with belt widths of 1.7" (42 mm) or 1.8" (45 mm)
Add a rank bar in black or red to mark stripes or instructor status
No two practitioners train the same way, so Isami builds this belt in three models instead of one, Slim & Soft, Thin & Firm, and Thick & Stiff. This green belt lineup is exclusive to ChokeSports.com, you won't find all three available anywhere else. If you like a belt that shows its history, Slim & Soft develops a visible patina as it wears in, a record of every session you put into it. Full details on each model, and what separates them, are below.
A Belt That Marks Where You Are in the Journey
Wear a rank that means something whether your path runs through BJJ, Karate, or Judo
Personalize every belt with embroidery, detailed further below
Get 10 standard sizes plus custom length for a fit that matches your frame
In Brazilian Jiu-Jitsu, the BJJ green belt is a youth rank, typically awarded to practitioners under 16 before they advance to blue belt, marking real progress on the kids and teens track. In Karate, the green belt karate rank is open to practitioners of any age and reflects steady growth toward the advanced ranks. In Judo, the green belt judo rank holds a recognized place in the kyu system as well, a step earned before brown belt. This belt looks different on everyone who wears it, some are chasing gold, some are chasing consistency, and this belt is built for both. Ready to order your Isami Green Belt? ChokeSports.com has outfitted serious martial artists with authentic Isami belts since 2006.
⭐⭐⭐⭐⭐ Kevin from Sweden "I got the ranked stiff colored belt (green) and it's by far the best solid belt that I have even owned. Thick, durable, easy to knot and looks just perfect. You can really feel that this is the real stuff."
⭐⭐⭐⭐⭐ Vladimir from Italy "I bought this green belt for my son, he is very happy. Really beautiful and of high quality. Surely my next purchase will be Isami again."
🧵 CUSTOM EMBROIDERY
Personalize your new martial arts green belt with beautiful embroideries in English and in Japanese. There are six fonts to choose from and 10 different colors. We reserve about 8in 20cm of each belt end for embroideries. Long text will be resized to fit within that space.
BELT FIRMNESS & EMBROIDERY
Isami belts now come in three firmness models, so you can match the belt to how you actually train. ➡️ F-350 is slim and soft, with a lightweight, "broken-in" feel from day one. We add the embroidery to the finished belt, so the stitching sits over the belt seams and the reverse side shows a visible trail. This is what we call "non-integrated embroidery." ➡️ F-400 is thin & firm, thinner than F-700 but with more structure than F-350. ➡️ F-700 is thick and stiff, built to hold its shape and take longer to break in than F-350 or F-400. Both F-400 and F-700 feature "integrated embroidery": we embroider the fabric first and then build the belt around it. There's no trail on the reverse side, and the belt stitch lines sit over the embroidery for a cleaner finish.
📏 BELT WIDTH: 42mm or 45mm
Now you can choose how wide your Isami Green Belt should be. The standard belt width is 42mm (1.65in) but we also make a wider variation that is 45mm (1.80in) wide. This is especially popular with bigger fighters/instructors who need a belt that will match their large frame.
🚿 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.

5 star quality belt!. When I bought it I took the stiff version with 45mm and with embroidery. As soon as I walked in the dojo my fellow karatekas started commentating on my new belt and how nice it looks. They said it really looks like a quality belt compared to the one we can buy in Sweden. I like the thickness it has when I tie the knot and it has great quality.I’m really happy I bought it and looking forward to buy the brown belt when I get my new grade.

I earned my green belt back in december, however I wasdissatisfied with the quality of my locally sourced belt. It leftsome paint residue on my gi and had an overall cheap feeling toit.For me, it is not just a belt, it is a milestone on my martialarts journey. I found your site and purchased a new one fromIsami. Not only did it arrive much sooner than expected, it alsobeat my old belt in every considerable metric. The overallquality is superior and I feel like this new belt will boost myChi through the roof.I just wanted to let you know, that I am very satisfied and willonly purchase new belts from you. Thank you.Kind regards from Germany.

Hallo Faras,First of all — congratulations on earning your green belt. That’s a big milestone, and we’re honored you chose us for something that meaningful.We completely understand what you said — a belt isn’t just fabric. It represents progress, discipline, and every hour on the mat. Hearing that your previous belt left residue and felt cheap must have been disappointing, so we’re especially glad the Isami Green Belt exceeded your expectations in every way.Isami’s craftsmanship truly stands apart, and knowing you can feel the difference — in quality, durability, and even in spirit — means a lot to us. “Boosting your Chi through the roof” is exactly the kind of feedback we love to hear.If you ever feel like sharing a photo of your new belt in action, we’d love to see it — here or on social media with #chokesports.Wishing you continued progress on your martial arts journey.Best regards,The ChokeSports Team
Can be pricey and takes a while for them to ship it from Japan but the quality is truly second to none.

I got the Ranked stiff Colored belt (green) and it's by far the best solid belt that i have even owned, thick, durable, easy to knot and looks just perfect, you can really feel that this is the real stuff. I were a bit concerned at the beginning of my order due to the expensive price and high shipping cost but it was worth every penny. So if you'd like to have a real martial arts belt there's really no need to look somewhere else than here.
