As reported by [rockpapershotgun]:

Toco Toco is a documentary series where various game developers like Suda51 of No More Heroes, Hidetake Suehiro of Deadly Premonition, Keiichiro Toyama of Silent hill, and Yoko Taro of Nier Automata, among others talk about their work and general hangouts and such. Some of them can be rather, ah, eccentric, such as Yoko Taro wearing a big moon mask helmet thing for the whole interview. The videos are in Japanese that use youtubes closed captioning subtitles, the series has two formats, one with 39 videos and the other 40 overall, but there are other interviews and videos on the channel [here].
