Even if we seek convenience and comfort in this informed world, we must not lose sight of ourselves.

In times such as these, we can explore for ourselves and make the most of “the marvelousness of martial arts for the world”. We will work towards connecting people with each other and do our best to create a new tradition.

By all means, we will treat you with sincerity and invite you to explore the culture of Japanese sashiko and martial arts.
We look forward to your continued patronage.

Defier's Philosophy and Vision


Here at Defier, we respect the spirit of Japanese martial arts and look forward to watching those who compete in the Japanese tradition of judo on the wonderful occasion of the Tokyo Olympics 2020.

Product Development

We have launched the brand Defier / ATELIER SABURAU, with the aim of continuing to develop our own judo wear. In addition to this is the inclusion of our own original contemporary versions of Japanese traditional crafts (such as sashiko and boro).

Our Dream to Nurture Judoka to Lead the Future

Defier has two judo masters who bring their own expertise to the company; one master, a two-time world champion who has taught judo all over the world, and another who has stood on the podium in Japan many times during his judo career, including running his own dojo for over 10 years.

Our dream is to help judoka, both in Japan and internationally, grow into global judoka of the future, who will become leaders themselves in time.
