Sega has announced a new Yakuza game for Japan. "Ryu Ga Gotoku: Ishin" (trans. Yakuza: Restoration) will focus on the early 1900s in Japan, during a time where Japan culture drastically shifted in an attempt to be more accommodating to Western ideas.
Kotaku reports that series regular Kiryu Kazuma will be playing a version of Ryoma Sakamoto in this spin-off title. Sakamoto was a historical figure who lived just before the restoration period, and who was a strong advocate to end the feudal system and incorporate more Western ideas.
Details, like platforms or a release date, are still unannounced. A US release seems unlikely. While a few of the Yakuza games have made their way Stateside, the Edo period spin-off Ryu ga Gotoku Kenzan for PS3 did not.
