About メガホンCH〜取材しながら企画する
Megaphone is a Japanese YouTube channel run by Eiji Yamada, who is named on the creator's website as the representative director and creative director of Shakai no Koukokusha, a social-theme advertising agency, and as a former Hakuhodo copywriter and filmmaker. The channel publishes long-form interview documentaries, mostly in Japanese, in which Yamada interviews social activists about hikikomori, school refusal, rural rail and similar issues.
With about 4,370 subscribers and a median of 1,337 views per video, the audience is likely small and concentrated in Japan, with an estimated skew toward adults interested in social causes. Uploads have stopped, so the channel is best viewed as an archive of past work.
