Welcome to the official website of the Kokusai Hojojutsu Kenkyukai (International Hojojutsu Research Society).

This group has been founded with the express intention of creating and supporting an active and open-minded international Hojojutsu community.

What is Hojojutsu?

Hojojutsu is the term used to describe the Japanese martial art of combative bondage; a system characterised by the restraint or immobilisation of an opponent using a length of cord or rope.

The two most commonly used names for this art are Hojojutsu 捕縄術 and the alternative reading of the same kanji; Torinawajutsu.

Although the tying methods, materials used and names of the techniques vary widely from school to school, we can broadly divide them into the following two categories.

Hayanawa 早縄 and Honnawa本縄.

The term Hayanawa translates as ‘Fast Rope’ and are generally simple, quick ties performed with a short, thin length or rope of between two and five metres in length.

In contrast the term Honnawa translates as ‘Main Rope / Head Rope’ and are designed to be far more secure, using much more complicated binding patterns as well as a longer length of thicker rope. These ropes were typically more than five metres in length.

In addition to its varying lengths of rope, Hojojutsu training may also employ additional tools in order to increase the effectiveness of it’s methods. Items such as the Kaginawa (Hooked Rope) Fundonawa (Weighted Rope) and Kakute (Spiked Rings) can all be employed easily and to great effect.


Hojojutsu 捕縄術 has existed in one form or another for as long as there has been a warrior class. But regardless of this long tradition, we at the Kokusai Hojojutsu Kenkyukai are not solely dedicated to the study of Koryu Hojojutsu, Nor are we specifically dedicated to the study of either Gendai or Goshin forms of Hojojutsu.

We are simply passionate about studying the art that is traditional Hojojutsu, regardless of its martial lineage or modern politics.

If this sounds like something that could be of interest to you, then welcome aboard.
