The Historical Background of Jiu Jitsu GIs

Jiu Jitsu, often termed as "the gentle art", boasts a lineage that dates back centuries. From the war-torn battlegrounds of Japan to the competitive arenas worldwide, the martial art has grown and transformed, and so has its attire: the Jiu Jitsu GI. But how did this attire come into being, and what is its significance?

Samurai Beginnings

It's said that the origins of the Jiu Jitsu GI can be traced back to the Samurai of feudal Japan. The Samurai, highly skilled warriors, needed clothing that would not hinder their movements in battle. They wore something similar to the modern-day GI, known as 'Kimono,' which was both flexible and durable. This Kimono allowed them to move freely, grapple, and execute various techniques without being restrained.

The Judo Influence

As time progressed, Judo, an offshoot of Jiu Jitsu, emerged and became highly popular, especially under the guidance of Jigoro Kano in the late 19th and early 20th centuries. The attire evolved with this new martial form. Kano, understanding the importance of standardized training gear, modified the Kimono to better suit the needs of Judo practitioners. This modified version was the precursor to the modern-day Jiu Jitsu GI.

Modern-Day Adaptation

With Brazilian Jiu Jitsu's (BJJ) emergence in the 20th century, the GI underwent further modifications. The Brazilians tailored the GI to be slightly more snug, allowing less material for opponents to grip. Today, with the global spread of BJJ, various brands, styles, and types of GIs have emerged, each catering to a practitioner's specific needs.

FAQs on the Historical Background of Jiu Jitsu GIs

Q: Why is the GI also called a Kimono? A: The term 'Kimono' is a nod to the historical Samurai attire that the modern-day GI evolved from. While 'GI' is the general term used in BJJ circles, 'Kimono' is a more traditional term still used by many.

Q: How did Jigoro Kano influence the design of the modern-day GI? A: Jigoro Kano, the founder of Judo, understood the importance of having a standardized training attire. He modified the traditional Kimono to make it more suitable for Judo's throws and takedowns. This modification laid the foundation for the current Jiu Jitsu GIs.

Q: Are there any significant differences between the GIs worn in traditional Jiu Jitsu and Brazilian Jiu Jitsu? A: Yes, there are subtle differences. Traditional Jiu Jitsu GIs tend to be looser, while Brazilian Jiu Jitsu GIs are more fitted to reduce the amount of material an opponent can grip.


I hope this provides an understanding of the historical background of Jiu Jitsu GIs. The journey of the GI, much like the martial art it represents, is rich, intricate, and full of evolution.
