This is a murders mysteries game, Funny that you mentioned Phoenix Wright! yes these are the closest games to Phoenix Wright in Japan they even have testimonies, and they are pretty big the last Phoenix Wright sold 500k while the last of this series sold 300k
the last one was Kyotaro Nishimura Suspense Series: Deadly Intent, here is an english interview http://www.cubed3.com/news/9532/
the stupid director/designer of the game said they will not bring it to the US because it have some japanese cultural references and american wouldn't like it, ignoring that phoenix Wright 2 was so amazingly cultural heave and that did ok in the US.
