高校生ヘルメット着用義務化10年、事故で息子を亡くし…講演活動に奔走する父の願い【愛媛】（2026年4月8日掲載）｜南海放送NEWS NNN

This page reports on Akihiro Watanabe from Matsuyama City, Ehime Prefecture, who has been conducting lectures to junior and senior high school students for nine years following the tragic loss of his eldest son, Daichi, in a traffic accident 11 years ago. Daichi was struck by a truck while crossing a zebra crossing on his bicycle as a high school freshman. Following this incident, Ehime Prefecture implemented mandatory bicycle helmet usage for high school students. Watanabe initially had mixed feelings about the mandate but later changed his perspective. His lecture activities aimed at reducing traffic accidents earned him the Nankai Broadcasting Award.
