We, Kusakura, are a judo clothing manufacturer. In fact, we have been spinning woven fabrics on looms for over 100 years since our founding.Nowadays, "Kusakura" is known all over the world for its judo clothing, but the fabric weaving part of judo clothing is not well known.There is no other manufacturer in the world that can consistently produce judo clothing from fabrics, in the meaning of an integrated production, as we have.The existence of "fabric" is large in judo clothing. We need to provide a safe cloth which can even been pulled by over 100k people throughout competitions. We are proud that it is "the strongest fabric that humans touch the skin".Sashiko cloth is used for judo suits.It can express a tough yet supple and warm texture.We want to convey the charm of sashiko cloth with its history and technique.And also started the project called "THE NEXT 200 TH".Based on the concept of "the world of strength and beauty of Japanese sashiko", the traditional Japanese sashiko fabric has been built up for more than 100 years. The so-called "kusakura-sashiko" fabric is of course in various forms with culture which we will send to the world.Judo suits maker Kusakura will continue to run for the next 100 years with the aim of becoming "Kusakura in the world beyond martial arts."

Pillar of 100 years Kusakura Sashiko

Kusakura Sashiko's techniques, such as thread handling, weaving techniques, dyeing blending,
sewing and embroidery techniques unique to Kusakura, are craftsmanship and attention to detail.
It is impossible to build a 100-year-old pillar without carefully and persistently stacking its parts.

Because you know the strength, you overcome your weakness.

From heavy fabrics using double weave to supple fabrics with single weave.
A wide variety of sashiko fabrics that are unique to Kusakura Sashiko, which is selected from threads.
100 years of history has created all the possibilities for sashiko cloth.
We like to present some typical fabrics.
  • JOA

    Pure cotton double weave

    Although it is a double woven fabric made of 100% cotton, it is gentle on the skin and has tough tensile strength by making 120% use of the pure cotton material.
  • JOF

    Blended double weave

    It uses a blended double woven fabric of 70% cotton and 30% polyester, while having the same feel and tensile strength as JOA, taking advantage of the characteristics of Kusakura Sashiko, which is comparable to pure cotton.
  • JY

    Blended single weave

    A blended single-woven fabric made of 70% cotton and 30% polyester. It has tensile strength while taking advantage of the softness that is characteristic of Kusakura Sashiko.
  • m46

    Single cotton weave

    The pure cotton single-layered fabric is commonly known as a face hat, and is used for the face comforter to soften the impact of the part hit with a bamboo sword.It is also used for kendo wear and is a single-layered fabric that is light and has the characteristics of sashiko weaving.

Japan's only integrated manufacturing

  • Woven fabric

    A judo garment that you can wear directly on your body. We pursue good touch while satisfying criteria such as weight and strength from the composition of the material. We realized the production of our "tough on the outside but soft at heart" fabric.
  • Dyeing

    Our dyeing surprised the world with a clean white and blue colors of judo clothing. Our dyeing process does not affect the soft characteristic of the fabric.
  • Cutting

    We worked on expanding fine sizes to suit a wide range of body types. In addition, we aimed a cutting which provides a feeling of fitting accuracy.
  • Sewing

    In order to make the collar as soft as possible, we change the width of sewing to 1mm. This cannot be reached by just cutting, such as a shoulder line that does not take weight, we are sewing in a sophisticated way.
  • Inspection

    For the purpose of maintaining high quality we set up an inspection room. We perform thorough inspections with strict measurements such as size to prevent defects in the product.
  • Embroidery

    After inspection, name embroidery is performed according to the customer's order. We have a large number of embroidery machines in place to respond immediately to customer requests.
