The All Japan Judo Federation has refreshed its safety-notice archive on head, neck and heat-stroke prevention, gathering in one place the past decade of warnings, PDFs and posters that have gone out to prefectural bodies and safety officers.

The archive includes the 3 June 2026 directive on the prevention of serious head/neck injuries and heat-stroke, the 10 April 2026 year-opening accident-prevention notice, and historical summer-heat documents going back to 2018. Each comes with practical guidance for instructors, dojo parents and beginners.

Hong Kong Judo summers are just as hot and humid as Japan's, so this material is directly useful for local dojos, coaches, parents and students — especially on the scheduling of training times, hydration, and the management of throwing and randori for beginners during the June-to-September window.
