Atmarkjojo.org

atmarkjojo.org (@JOJO) is a Japanese fan site for JoJo's Bizarre Adventure and Hirohiko Araki that was active from 2003 to 2017. The site was created by SHATO (シャト) and is notable for being the first and longest running news site dedicated to the series.

History
In 2003, SHATO created the site as a way to gather information about the series online for himself and other core fans. SHATO expected the site to quickly run out of new content with the ending of Stone Ocean, but it soon grew larger and larger, lasting for almost 14 years. As other sites such as Comic Natlie and araki-jojo.com begun appearing, SHATO felt less the need to keep updating the site. Unable to keep up with overwhelming amount of content that was brought about with the new anime, SHATO decided to cease all activities on the site, posting a farewell message on February 16, 2017.

As of 2021, the site still remains open, serving as an archive for all previous posts.
