About Us

Two decades of tradition, discipline, and community in the heart of Shibuya, Tokyo. This is the story of Ember Storm Weave.

Founded on the Way of the Warrior

Ember Storm Weave was established in 2001 by Sensei Kenji Tanaka, a National Kendō Federation champion who had trained for thirty years under the great masters of Kyoto and Osaka. His vision was simple and uncompromising: to create a place in Tokyo where the classical martial arts could be taught with full fidelity to their tradition — no dilution, no shortcuts, no sporting compromise.

The dojo opened its doors in the Miyamasuzaka district of Shibuya with three tatami bays, a full-length kendo floor, and a handful of students. Today it hosts over two hundred active members from more than forty countries, and retains every one of the founding principles that Sensei Tanaka inscribed on the original dojo charter in the autumn of 2001.

From Tradition to Community

In the early years, Ember Storm Weave remained deliberately small. Sensei Tanaka rejected all offers to expand or franchise, believing that authentic martial training could only flourish in intimate, direct relationship between teacher and student. This philosophy continues today.

Word spread quietly through the international martial arts community. Practitioners from around the world began seeking out the dojo, drawn by its uncompromising standards and the depth of instruction. By 2010, we had outgrown our original space, and moved to our current location in Shibuya, where we have carefully expanded without sacrificing the human scale and quality of training that define us.

What We Stand For

Three Pillars of the Dojo

Every decision we make — from curriculum design to dojo etiquette — flows from three core commitments we have never compromised.

Authentic Instruction

We teach from unbroken classical lineages. Our sensei hold grades of 5th dan or higher, certified by Japan's national governing federations, and have trained directly under the traditions they now pass on.

Open Community

From age 12 to age 70, every background is welcome. The mat is a leveller. A new white belt receives the same respect and attention as a seasoned senior student.

Safety & Respect

Strict dojo etiquette, padded tatami, and rigorous safety protocols protect every practitioner. Mutual respect between students and teachers is non-negotiable — it is the foundation of all practice.
