is one of the major suppliers of Karate gis and belts to famous fighters, senseis and organizations all over the world. In fact our parent company Isami has a very long and deep history with Kyokushin Karate in Japan. 

Sosai Masutatsu Oyama, founder of the Kyokushin Karate style, was an acquaintance of Mr. Shigeyuki Iso, Isami's president. At first Sosai Mas Oyama would wear our unbleached full contact dogi  Isami K-400 Classic. This is Isami's most traditional Karate uniform. He later switched to the newer and improved version: Isami K-500 (which we now call "Mas Oyama"). He chose it because it was the most long-lasting and easy to wear Karate Gi he had ever tried.

As the K-500 became Sosai Mas Oyama's favorite uniform, Isami decided to provide a bunch of sets for him to wear during the year. He would use a brand new dogi for a while and then pass it along to his Deshi (pupil) as a present. That's how the Isami K-500 reputation started to spread in Japan. To this day it is a symbol of Karate Ka who are striving in training. Despite the recent growing popularity of bleached white Karate Gis, some people in Japan will only wear the Isami K-500 (unbleached).

Sosai Mas Oyama used to say: “Train hard, and train until the dogi color becomes white”. What he meant was that unbleached ivory Karate Gis like the Isami K-500 and Isami K-400 will eventually become white after repeated training and multiple washes.

What Customers Are Saying About Chokesports

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 no 1. I had communication with Lisa Andersen. She wanted to be sure that my order was the right one for my new Shodan young girl. Very dedicated to the client. Simply the best.

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 even including the time allotted for custom patchwork. Extreme recommend to anyone on the fence. Much respect always to ChokeSports.

Best gi from best vendor. This is my third Isami Gi purchase from ChokeSports. I use them for Judo and BJJ. They fit the best, and they feel the best. Super fast shipping too. Rest assured I will order my fourth Isami Gi from ChokeSports in the future.

I want to congratulate the whole company, not only for the excellent work with the black belt I bought, but mainly for the support I had from the first steps of ordering. Connor's help was valuable through the chat line, up to the emails informing me of every detail. My colleagues and I will recommend your company. Thank you!
