Description
Ryosuke Ozaki, Kenji Hosokawa, and Kenichi Nishimura survey judo instructors across all 47 Japanese prefectures on children who need extra support. Community clubs are a major sports home for children with neurodevelopmental disorders, yet national counts were missing. Their 2026 survey covers 1,104 clubs and programs with 15,360 child participants in all.
Instructors flagged 1,079 children, or 7.02 percent, as needing extra support. The share fell with age, from 12.13 percent in preschoolers to 0.79 percent at university level. Known diagnoses ran far lower: ADHD at 1.57 percent, autism at 0.68 percent, learning disorder at 0.70 percent, and coordination disorder at 0.09 percent. Even summed, known diagnoses cover under half the support need. The authors urge coaches to plan help by need, not by diagnosis labels.
