All Japan Judo Federation

What All Japan Judo Federation does

The All Japan Judo Federation (全日本柔道連盟 / AJJF) is Japan's sole national governing body for judo, established as a public interest incorporated foundation (公益財団法人) in 1945 and headquartered within the Kodokan in Tokyo's Bunkyo ward. It operates the complete judo governance stack in Japan: nationwide membership registration and licensing for athletes, coaches, and referees; organization of national championships and selection for international competitions; coach and referee certification including e-learning renewal; athlete development pathways from cadet (D) through senior (A) national team tiers; and programs targeting women, youth, disabled practitioners, and veterans.

Its technology infrastructure centers on the Judo-Member online registration and qualification management system, a self-service member portal, an e-learning platform for instructor and referee certification renewal, a Dojo Navi nationwide directory, an Athlete Management System for elite national team rosters, and a Competition Entry System for tournament administration. Content and engagement are delivered through the official website, the 「Zenjuren TV」 YouTube channel, an official Note publication, and the Digital 「Mind」 web magazine. Business model revenue is diversified across six streams: recurring annual membership registration fees, tournament entry fees, instructor/referee certification fees, merchandise sales, corporate sponsorship (Park24, Mizuno, Seiko, Komatsu, JAL, JR East, Mitsui Sumitomo among others), and Japan Sports Agency / government subsidies. Customer segments span competitive athletes, coaches, referees, youth, women, disabled practitioners, and veterans across 47 prefectural judo federations, with international reach via IJF and Asian Judo Union participation.

Direct peers

• Brazilian Judo Confederation (CBJ): Brazil's national judo federation, also an IJF member. Shares AJJF's mandate of athlete development, certification, and competition organization across a large domestic base, with a comparable non-profit federation structure.
• USA Judo: National governing body for judo in the United States and a fellow IJF member federation. Operates a similar mandate of national team selection, coach/referee certification, and domestic tournament organization under comparable non-profit governance.
• Korea Judo Association: National judo federation of South Korea and a long-standing rival in international competition. Operates the same functions — national team management, certification, domestic tournament organization — and competes with AJJF for Olympic medals.
• Fédération Française de Judo (FFJDA): France's national judo federation, one of the strongest judo nations globally. Operates the same federation functions as AJJF — national team management, certification, domestic competition — making it a direct structural and operational peer.
• All Japan Kendo Federation: National governing body for kendo in Japan. Operates an essentially identical federation model under the Japan Sports Association umbrella — domestic competition, instructor/referee certification, prefectural chapters, and Kodokan-style heritage branding.
• Japan Karate Association (JKA): One of Japan's major national karate organizations, with a comparable mandate of athlete selection, instructor certification, and international event participation. Shares the Japanese national-sport-federation structure and martial arts heritage positioning.
• Japan Wrestling Federation: National governing body for wrestling in Japan. Operates under the same Japanese federation framework with comparable functions: national team management, Olympic qualification, coach/referee licensing, and partnerships with Japan Sports Council.

Regional players

• European Judo Union (EJU): Continental judo federation coordinating European championships and development. Sits alongside AJJF in the IJF hierarchy as a regional peer rather than a direct national-federation competitor, but addresses the same athlete pathway and event organization challenges.

Others

• Kodokan: The spiritual and technical center of judo founded by Kano Jigoro in 1882, hosting AJJF's headquarters and acting as a flagship strategic partner. While not a direct federation competitor, it sits at the apex of the judo ecosystem and shares AJJF's heritage-based brand equity.

Broad incumbents

• International Judo Federation (IJF): Global governing body for judo headquartered in Budapest. AJJF participates as a member national federation in IJF World Judo Tour events. The IJF sits one tier above AJJF in the federation hierarchy and is a mutual strategic partner.
