Discover the MEIRIN KA-19 Black Ninjutsugi, an authentic Japanese martial arts uniform manufactured in Japan by MEIRIN(明倫), a Japanese company specializing in traditional martial arts clothing and equipment.
Made from 100% cotton, Japanese No. 11 canvas (11号帆布), this traditional black martial arts uniform combines durable construction, comfortable movement, and Japanese craftsmanship.
Originally designed as a traditional black Karate Gi, the MEIRIN Black #11 Cotton Uniform is also an excellent option for practitioners seeking a Japanese-made training uniform for Ninjutsu, Ninpō Taijutsu, Bujinkan Budō Taijutsu, Kobudō, and other traditional Japanese martial arts.
Its structured cotton fabric and traditional cut make it particularly suitable for martial artists who value durability, unrestricted movement, and authentic Japanese manufacturing.
Important: KA-19 is the manufacturer's reference for Size 2. The same black cotton uniform is available in additional sizes under the references KA-20, KA-21, KA-22, and KA-23.
Authentic Japanese Craftsmanship – MEIRIN(明倫)
MEIRIN is a Japanese supplier of traditional martial arts uniforms and equipment, offering garments manufactured in Japan with an emphasis on practical construction, quality materials, and freedom of movement.
The MEIRIN Black #11 Cotton Uniform reflects the principles of traditional Japanese martial arts clothing: simplicity, durability, functional design, and comfort during practice.
According to the Japanese manufacturer's product description, MEIRIN uniforms are produced in Japan using carefully developed sewing techniques intended to provide a comfortable fit and natural mobility.
The traditional black appearance makes this uniform especially appealing to practitioners seeking authentic Japanese martial arts clothing rather than recreational costumes or decorative ninja outfits.
100% Japanese Cotton – No. 11 Canvas Construction
The MEIRIN Black Ninjutsugi is manufactured from 100% cotton No. 11 Japanese canvas, known in Japanese as 11号帆布(11-gō hanpu).
This cotton canvas provides the strength and structure required for traditional martial arts training while allowing the body to move naturally.
The manufacturer describes this material as a substantial, heavy-duty cotton fabric that offers durability and comfortable movement.
For international martial arts practitioners, No. 11 canvas can be described as a structured, medium-to-heavyweight cotton fabric. However, the number 11 refers to a Japanese fabric classification rather than an exact garment weight in grams.

Suitable for Traditional Ninjutsu and Ninpō Taijutsu Training
Although MEIRIN originally manufactures this model as a traditional Japanese black Karate uniform, its construction also makes it suitable for many forms of Japanese martial arts practice.
For practitioners of Ninjutsu and Ninpō Taijutsu, the uniform offers a practical combination of durable cotton fabric and a traditional training design.
The garment can be used during martial arts practice involving standing postures, body movement, controlled partner exercises, and technical training.

These traditional waraji sandals were very well crafted. Authentic and holds the period look. I recommend Bujindo as a source of high quality goods!
I would like to express my sincere gratitude for the excellent service and the smooth handling of my purchase. I was extremely satisfied with the entire buying process, and everything was handled professionally and efficiently.
I would especially like to mention that the Samue is absolutely beautiful. It exceeded my expectations, and I was truly delighted when I received it. I greatly appreciated that everything went so smoothly from start to finish.
Thank you very much for your care, attention, and outstanding service. I wish you continued success and hope to purchase from you again in the future.
Excellent experience with this e-shop which I do recommend for their really nice selection and for their precious advice.
The Tabi boots I get are exactly how I expected them.
As an US 10 the 28 is perfect.
Japanese traditional style to walk through the streets of the world
Hervorragende MaterialQualität zum fairen Preis.
Domo Arigato gozai masu!🙏
My haori arrived in a timely manner and was everything I expected it to be and more. The quality of the haori is fantastic, and it fits great!
This pair of shoes is really very comfortable, and the craftsmanship is excellent. It's exactly what I expected. The only problem is that I ordered a pair half a centimeter larger than my usual size, and even so, they're so tight that I can't even wear socks (tabis)!
I loved them, very beautiful and perfect fit if you follow the measure instructions. Looking forward for some outdoors bujinkan training in the spirng!
I wish they would come in 12 version as well
Thank you very much
Just like described, fast shipment. Nothing to complain about :)
The Samue suit is very beautiful crafted - the fabric is soft and very pleasant to wear. A high quality clothing that exudes a genuine Japanese feeling attention to detail. . The tabi shoes clearly high quality. I am very happy.
Super cozy!
out est parfait. Merci
heads raised to the heavens, i am not worthy of the energy without thy consent.
Comfortable and visually stunning
Just the right size.
As this belt was a replacement for my original black belt from 2003, I am very pleased to say that it has the same feel and quality of my previous belt. I teach karate 5 days a week, so I need a belt that stands the test of time. I am positive that this is it!
