Ryū ga Gotoku Kenzan!

The gameplay shows minimal evolution from the first two episodes except for the new item storage system which allows access to an unlimited number of items from savepoints.[5]

There are four fighting styles in the game; fists, one blade, two blades and two-handed blades. There are also QTE-based special moves that the player can execute, known as 'heat action'.[5]

This spin-off is set in Kyoto during the Edo period, in 1605. It is an account of the life of Miyamoto Musashi. The main adventure is completed with sidestories including minigames and a hundred "sub-stories".[6]

After being defeated by the Tokugawa clan at the historical Battle of Sekigahara which took place on October 21, 1600, Miyamoto Musashi retired from his great swordsman life to become a modest yojimbo (bodyguard) in Gion (祇園), Kyoto. Five years after the battle, a little girl named Haruka comes to Gion seeking a local hitman known as Kazumanosuke Kiryu which is actually Miyamoto's new identity. After eventually finding Kiryū, Haruka asks for him to assassinate an impostor pretending to be Miyamoto Musashi. At first, Kiryu refuses, then when the girl goes as far as becoming an indentured servant in an opulent oiran brothel in order to pay the assassination mission he accepts the one-ryō request.

Cyberware Inc.'s facial scan technology was used with main characters and fully exploited on the Event Mode's high polygon models. Here character Gion Toji borrows actor Takashi Tsukamoto's physical appearance

This is the first game in the series where the games' main characters have their face modeled in 3D after their voice actors who are Japanese celebrities.[7] Cyberware's color 3D scanner (model PS)[8] was used to analyze each actor's head & face in order to collect data on its shape and appearance, then this file was worked with the Softimage XSI 3D graphics application.

As part of the pre-ordering campaign, the Japanese first print was bundled with a limited item, a monography called Kamutai Magazine (March 2008 issue). Sony celebrated the Japanese release of the game with a 10,000 pieces limited edition Satin Silver 40GB model "PlayStation 3 Like a Dragon Kenzan!

In late December 2009, commenting the opportunity of a western release, Sega Australia managing director Darren Macbeth said "there is nothing in the plan at this stage for Yakuza Kenzan. Right now we are focusing on the release of Yakuza 3. The feedback we get from this release will help us in making future decisions".[2] In March 2010, Yakuza 3 had a western release as did in 2011 Yakuza 4. Then again, in 2012, a second spinoff was also released abroad and localized as Yakuza: Dead Souls.
