What this site is
Judo Gokyo shows the 40 throws of the Kodokan Gokyo as interactive 3D animations. Every throw is split into its five phases – kumikata, kuzushi, tsukuri, kake and the finish – with key points and arrows that show where the force goes and how Uke reacts. Around the animations you find a judo glossary, a printable body-parts chart and the classification of judo techniques.
So far 8 of the 40 throws are animated; the others follow step by step.
Who makes it
Judo Gokyo is a private, non-commercial project by Björn Linder, a judo practitioner and trainer from Germany. It started as a teaching aid for my own training sessions: a way to show what happens in a throw slowly, from every angle and as often as needed. There is no advertising, no tracking and no paid content.
How the animations are made
- Each throw is modelled on the official Kodokan × IJF Academy reference video, studied frame by frame and from every camera angle; the video is linked on each technique page.
- Both judoka are right-handed and grip in ai-yotsu. Tori wears white, Uke blue.
- At 1× the animation runs at about real speed; the page starts at 0.25× so you can follow every step.
- Every throw is checked against the video and corrected before it is published.
Official sources and further reading
The throws and terms on this site follow the Kodokan. For the original sources, competition rules and coaching education:

Please note
The animations simplify real judo – bodies, grips and timing are idealised. They support, but never replace, practice on the mat under a qualified coach. If something looks wrong or unclear, please let me know.
