JoJo is a really popular and old manga series in Japan. It also has an anime currently running which would explain its popularity boost. There's also a second anime that makes a large number of direct references to JoJo currently running as well.
The game looks gorgeous: http://www.hmv.co.jp/news/article/1302190014/ for some screenshots...
It's been sitting at #1 on Amazon JP for over a week already...
