lol, thanks for the clip.
i watched a walkthough to remind myself because it's pretty quickly glossed over that the yakuza are a presence in shenmue. the clip shows one player asked a few questions in that office then walked out. probably why i forgot. - i'm a fan but i don't religiously play shenmue that much anymore. i over did it and completed shenmue 1/2(dc) too many times in 2000-2007, then only replayed s1/2HD(ps4) again in 2019 for s3. ( the more times i played shenmue, the more sad it made me feel that the story had no ending).
i'm not 100% on japanese history/culture but in recent years when i hear the word yakuza, i think of one of the worst organised crime gangs around.. which could of been worse than the mad angels as a main enemy in shenmue 1.
