AKBAN ([1]), "Light guard", is an international system specializing in old school Ninjutsu, fitness and health. The school's name is augmented from the words light and guard in Japanese. The AKBAN school was founded in Israel by Yossi Sheriff in 1986.

The school is Seishin Teki Kyoko and koryu based. It is informally abberviated by it's students as simply Irgun or The Organization, and trains students in Martial arts, Emotion regulation, Meditation, Fitness and outdoor skills. AKBAN veterans teach in Israel, Greece, Canada, Germay and instruct a small core of approximately 300 undergraduates and veteran students.

It takes 12 to 13 years to qualify for a black belt exam.


The school was founded in 1986 in Jerusalem by Yossi Sheriff, a Bujinkan senior instructor and a student of Doron Navon, the first non Japanese Shihan in Bujinkan Ninjutsu school. Yossi Sheriff passed his Godan test in 1991 under Hatsumi Sensei.

Shihan Navon started instructing Judo and Ninjutsu as a Bujinkan Shidoshi at a village dojo near Tel Aviv at the year of 1977. After teaching and authorizing several instructors Doron stopped teaching at the beggining of the 90's. At 1992, in conjunction with Bujinkan Israel the school wrote and directed the first state sanctioned Ninjutsu/Budo Taijutsu instructor's course.


The AKBAN system offers classes for those who want to master Martial arts. The program is authorized as a non-competitive martial arts school by the Israeli ministry of Science Culture and Sports [1]. The Akban School also issues ranks. The relatively long time span for belt exams stems from the large syllabus learnt. The modernized Kyu system is used and the minimum time in dojo before a black belt exam is 12-14 years.

Akban-wiki, The Akban project

General background

The AKBAN project is a non commercial, not for profit, effort to collect, create and freely spread knowledge about Ninjutsu, martial arts and related fitness programs [2] Its main features reside in the main website of the school. The chief feature of the AKBAN project is a community online encyclopedia.

Description of the Akban-wiki

The Akban-wiki has thousands of articles and videos written by Yossi Sheriff.

The project started in 1998 when two veterans started organizing the vast Takamatsu den syllabus learnt in AKBAN into a computerized database. The methodical backbone of this project was a system for allocating different stages of learning in martial fields called the Methodical Pyramid [3].

Many fields have benefited from the sharing and distribution of safe knowledge and training methods. The huge amount of material practiced in the necessitated means to organize and validate the techniques used. In 2005, the work on the database shifted toward a mash-up of user generated media on a wikimedia platform.

The project organizes visual materials in a semantic web. This is achieved by installing a Semantic wiki and starting to apply interrelations between the techniques of same and different martial arts. The videos and articles are tagged with categories and the categories hierarchically nestle inside meta categories using a logical tree. The semantic functions allow the Akban-wiki skilled user to give each article and video attributes and describe the relations between them.
