Sega appears to be going with a "5" theme for Yakuza 5. Joining the previously announced five cities, the game will also have five main characters. This is one up from previous titles, which have had at most four main characters.
The full Japanese name for Yakuza 5, as revealed in Famitsu this week, is "Ryu ga Gotoku 5: Yume Kanaeshi Mono." A rough (very rough) translation would be "Yakuza 5: Person Who Fulfills Dreams."
This early report from Famitsu comes via our usual flying get source, Sinobi. Sinobi also says that the game seems like it may be released in December (the phrasing suggests that it's not stated directly in the magazine).
As detailed in November, the five cities were previously announced as Sapporo, Tokyo, Nagoya, Osaka and Fukuoka. Series producer Toshihiro Nagoshi also previously confirmed that Kazuma Kiryu would be one of the main characters.
It's unclear at present if Famitsu has additional character reveals, but we should be getting more details later in the day.
