At first i thought it´s easy to recommend something (since those are kinda my favs), but honestly it´s harder than i thought ...
Most of the one i read aren´t just "classic yakuza" ... since i´m not sure what you´re looking for (more like big lifestyle yakusa-boss or shady business street fighting or rather respect the old ways etc. i start with those:
- "Heat" is for me a "classic Yakuza storie", nothing more to say
-"Tong" and the following "Tong Classified", Tong Vanity" = "Neo-Yakuza". I think Tong isn´t what you are looking for, but the following are in my eyes ^^
- i liked "The Fable" a lot, which is about a first class killer, that has to lay low for a bit. Naturally he is surrounded by (old school-)yakuza-members that can´t leave him be.
- if you want to see the dark sides of society and the streets, maybe "Out" is just right. Got no style, but a lot of fighting with blood and gore
- if you want something funny that Majima-San would surly approve: "Gokushufudou: The Way of the House Husband" (Kinda hard to not heard about this one thought ...
)
- if its about the ~heart of an old school yakuza~ -> i just recently stumbled over "Yakuza Reincarnation" xD that old man is and old school yakuza through an through ^^"
You can PM me, if you like got some more <3
