Welcome  to the official website of


     The mission of Itosu-ryu Karatedo International Federation is to preserve and promote the classical Karatedo called ITOSU-RYU. It was established by the great Okinawan karate master Anko Itosu (1835 - 1915) and passed down to Kenwa Mabuni (1889-1952) to Ryusho Sakagami (1915-1993) and to the current Soke (the 4th generation grand master) Sadaaki Sakagami.

    The original organization "Japan Karatedo Itosu-kai" was established in Kawanishi city, Hygo prefecture, Japan in 1940. With the internationalization of karatedo, our school also aims to develop intercultural relationships and understanding throughout the world. To this end, we formed an international organization called Itosu-ryu Karatedo International Federation(IKIF) in August 2002 comprising of 16 countries. IKIF now has over 20 member countries.

     The purpose of this site is to unite the worldwide family of Itosu-ryu practitioners as well as  be a source of information for those interested in learning more about our history and style. For more information on how to become affiliated, please feel free to contact us.

Karatedo Championships

Dates: 4th - 7th August 2022

Hosted by Itosu-kai, Denmark

     Because of the worldwide spread of coronavirus (Covid-19), many dojos were obliged to close and as a result training for everyone was interrupted or discontinued. I believe that the vast majority of tournaments, local, national and international have also been postponed or cancelled and this may have demotivated students from practicing karate.

     To alleviate this situation, we are planning on holding a “virtual tournament”. This is a new venture for Itosu-kai giving students the opportunity to compete in competition. The accompanying “Tournament Outline” explains how the tournament operates and details how videos of kata are to be taken and sent for viewing.


     We are looking forward to seeing as many members as possible from Itosu-ryu Karatedo International Federation (IKIF) participating in this event, and we would like to keep the originality of out previous international “kata” championships. We ask you to inform all your students of this international competition and to participate and be part of this first-time historic event.

Again, please take care of yourself in this pandemic.
