Dスタ！: A Boxing Gym Built Around the First Step
A Narashino boxing-fitness gym where former Japanese welterweight champion Daisuke Sakamoto trains beginners, families, and aspiring fighters.
Field notes
The gym separates its timetable by age and attendance pattern, including adult three-times-weekly plans, twice-monthly reservations, children’s classes, and a family plan for a child through sixth grade. Its mental-training offer is presented as a method for understanding the brain’s response to anxiety and deliberately changing one’s interpretation or reaction. The site also records Sakamoto’s competitive path, including a 2017 Japanese title win and his 2018 retirement.
