Meaning

Attention Deficit Hyperactivity Disorder — a neurodevelopmental condition increasingly recognized and discussed in Japan.

ADHD has become one of the most talked-about mental health topics in Japan, particularly regarding adult ADHD (大人のADHD). Many Japanese adults are discovering they have ADHD after years of struggling with focus, organization, and impulsivity that they attributed to personal failings. Social media has been transformative — ADHD creators sharing coping strategies and daily life experiences have built massive followings. The English abbreviation ADHD is used as-is in Japanese, alongside the formal name 注意欠如・多動症.
