• Founder: Kanō Jigorō (1882) – synthesized jujutsu into modern sport/education system.
• Education: Mandatory in many middle/high schools; university clubs ubiquitous.
• Olympic Sport: Since Tokyo 1964; Japan dominates medal table (84 golds as of 2024).
• Infrastructure: Kodokan (Tokyo) = world HQ; 2,000+ dojos nationwide; All Japan Judo Federation.
• Cultural Status: Budo (martial way) = character building; police, military, corporate teams.

Other Major Arts

• Kendo (swordsmanship) – 2M+ practitioners; school clubs.
• Karate (Okinawan origin) – 4 main styles; Olympic since 2020.
• Aikido – spiritual/self-defense focus.

Judo's blend of sport, education, and philosophy makes it Japan's de facto national martial art.
