The game was first teased back in March with a shot of the Kamurocho district from previous Yakuza titles (now seen more clearly in the gallery below). More recently, Japanese audiences were treated to a teaser ad highlighting a possibly wrecked Tokyo as the game's setting.
For those of you who can read Japanese, the site offers a short blurb about the game alongside computer wallpapers and a set of folder icons for both Windows and Mac. Nope, no screenshots or videos yet, just stuff with which to dress up your computer. We're hoping to see the game in action at Tokyo Game Show next week.
