JoJo's Bizarre Adventure's 25th Anniversary

The JoJo's Bizarre Adventure series celebrated its 25th anniversary of publication on January 1, 2012. The anniversary was a promoted milestone for the series which resulted in the occurrence 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 occurring 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)popularization of the franchise within Japan and overseas.

Hirohiko Araki JoJo Exhibition 2012
The Hirohiko Araki JoJo Exhibition 2012 was a special event first held in Sendai, Japan from July 28 to August 14, where JoJo's Bizarre Adventure creator, Hirohiko Araki, presented various works of art to celebrate the 25th anniversary of JoJo's Bizarre Adventure. In the press conference of this event held on July 5, a new PS3 game and anime adaptation were revealed.

VS JOJO
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 would adapt the universe of the series into three light novels.

25 Years With JoJo
A booklet titled 25 Years With JoJo was bundled with the October issue of Shueisha's Ultra Jump magazine. In it several mangakas, notably from Shueisha or CLAMP, made a collective tribute to the series in the form of a drawing and a complimentary note.

JoJo Royale
An online tournament named JoJo Royale was held on Google+. Replicating the organization of the Steel Ball Run race, nine stages with different rules and different separate prizes as well as a prize for the winner were made. The first stage was a written quiz about the series, and had for prizes a drawing of Rohan Kishibe by Araki; the second stage was a contest for whoever uploaded the best photograph of a woman making a pose, and the prize was a replica of the Stone Mask.
