JoJo's Bizarre Adventure's 25th Anniversary

The JoJo's Bizarre Adventure series celebrated its 25th anniversary of publication in January 1st, 1987. The anniversary was a promoted milestone for the series which was the occasion for the happening of many promotional events as well as the release of promotional materials, most notably JoJo's Bizarre Adventure: The Animation.

Description
The 25th Anniversary of JoJo's Bizarre Adventure was a year-long promotional event occuring during 2011, the entirety of 2012 and continuing into 2013 during which the JoJo's Bizarre Adventure series and its author Hirohiko Araki's success was celebrated. It was also a widespread promotional event in Japan which has been a key factor for the (re)popularisation of the franchise within Japan and overseas.

As a tie-in between Araki's 30th year as a mangaka and JoJo's Bizarre Adventure's 25th birthday, JUMP j-Book announced the VS JOJO Project for which several authors will adapt the universe of the series into three light novels.

For the release of the booklet 25 Years With JoJo, several mangaka notably from Sheisha or CLAMP, made a collective tribute to the series in the form of a drawing an a complimentary note.
