Protoman85 updated his Youtube review series of the Yakuza franchise by covering Yakuza Kenzan! and the Yakuza movie.
Yakuza Kenzan! was the Yakuza franchise’s entrance into the next generation of consoles after the PS2. There are quite a few similarities to Ishin: namely, the presence of multiple fighting styles, playing “as Kazuma” under a different name, and the Edo period setting. Shortly after this game came out, Yakuza 3 was released, and though the latter was localized Kenzan! never left Asia.
The Yakuza movie is a live action adaptation of the first game. It was released to Japanese theaters in 2007 and directed by Takashi Miike, who might be recognized for the 2012 Gyakuten Saiban/Ace Attorney film among the eclectic tastes reflected in his extensive portfolio. As someone unfamiliar with all of his work, it seems by the time Miike worked on the Yakuza movie he was quite acquainted with depicting violence and the yakuza. The movie was released with English subtitles on DVD in 2010. The only acquaintance I have with the movie is a scene where Goro Majima and his gang look for Kazuma Kiryu, and personally it left a good impression.
