These Yakuza videos are basically the only Yakuza content I've ever been exposed to, so I'm glad they're as entertaining as they are; it's a fun way to experience these stories. Also the sound editing in this one was great, the Smash 64 sfx always made me laugh.
Watching the videos all the way through is a big factor to pushing it out to more people, as well as interacting via comments/likes and stuff like that.
What I find interesting is that 10B yen is only like… what? 65Million USD? So they waged war for that amount of money? Especially considering like a million yen isn’t even an average salary in Japan.
I think it may be worth a bit more with inflation, but the biggest reason all the Yakuza families wanted to retrieve it was to earn the respect of the other families and getting the leader of their respective family to become the next chairman (which is probably the biggest draw). The money belonged to the entire Tojo-Clan, so it's not like they would be getting all the money if they found it.
