BELT MODEL: Which one is right for you?
➡️ F-450 has a broken-in feel and is easy to tie.This is a slim belt with a stiff core. When this belt starts to fray, the white inner core will show.
➡️ F-742 feels hard and sturdy around the waist. This is a standard thickness belt with a stiff core. When this belt starts to fray, the black inner core will show. ➡️ F-700 is the thickest and hardest 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.
🧵 CUSTOM EMBROIDERY
Personalize your new karate black 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.
INTEGRATED EMBROIDERY
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!
📏 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.

What Isami belt size am I?
Step 1: Measure your waist
Use a measuring tape to measure your waist where you would typically wear your BJJ belt. Make sure the tape measure is snug but not tight.
Step 2: Use the waist measurement to determine your belt size
Our Isami belts follow the size chart below:
A0 (100in 255cm): waist up to 27 inches
A1 (108in 275cm): waist 27-31 inches
A2 (116in 295cm): waist 31-35 inches
A3 (122in 310cm): waist 35-39 inches
A4 (128in 325cm): waist 39-43 inches
A5 (134in 340cm): waist 43-47 inches

Custom Size Belts
But what if none of the standard sizes feel right for your body type? Here at ChokeSports.com we have the expertise to custom make a belt in the exact length that you need. Please select the option "Custom Length" in the size selector and then type your desired belt length in either inches or centimeters.
🚿 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.
BELT SHRINKAGE
Your new Isami 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%

Isami Karate Black Belt Premium
Great quality belt. It’s a little thicker than I expected but still an awesome belt.
Hello Leon.
Thanks for sharing your feedback with a photo of your custom black belt. The gold embroidery in Japanese Gyosho script font looks so nice! And yes, the F-700 black belt model you selected is the thickest and hardest of all belts we make, as stated in the product page.
Best regards from your friends at ChokeSports!
Hello William.
Thanks for the positive feedback and for sharing the pictures of your new custom black belt. Looks super nice and clean with the golden stripes stitched all around the stiff core F-700 belt. We hope it will bring you extra energy during your Karate sessions (-;
Regards from everyone at ChokeSports.com!
