Tokyo Vice by Jake Adelstein is a good read for those interested in this scene.

For a comedic take on Yakuza (in part), "A Stranger of Mine" (運命じゃない人 Unmei janai hito) represents a 2005 Japanese film by Kenji Uchida, starring Yasuhi Nakamura, Reika Kirishima, Sō Yamanaka and Yuka Itaya: https://en.wikipedia.org/wiki/A_Stranger_of_Mine

Thanks! Will check this out. I love all of Beat Takeshi's movies.

Agreed, it's also just a cracking read. Adelstein is insane, in a good way.

100% haha

The cause: "The direct cause of the 2015 split was money. The Yamaguchi-gumi levies a tax on all of its affiliated factions to the tune of 1+ million yen (~ $8,100) a month. However, not being able to bear such an expense any longer, certain factions decided to rebel and form the new “Kobe Yamaguchi-gumi” organization."

Indirectly, the article quotes shifting Japanese public opinion about "designated organized crime groups" and their place--or rather, their lack of it--in society.
