The Fudebakudo animations used to be in Flash (a technology from the Shōwa period that was once widespread on the web). Now they are hosted on YouTube.
* This animation also appears in the book.

Frustratingly, Fudebakudo has never been nominated for any documentary film-making awards despite being responsible for this now-classic example of martial arts reportage.
