Yakuza references in Shin Megami Tensei 4?

I’ve been playing Shin Megami Tensei 4 for the last week and just got to Kabukicho.Instant nostalgia trip from the arches and the Don Quijote to the right of it.

Further down the street we’ve got Club Stardust and the Yakuza that guards access to the area looks so much like Kiryu.. these have to be references right?!
