  
Quick note: I forgot if this was explicitly stated in the games, but Yokohama Chinatown is strongly associated with Peking Duck in Japan, and was billed as the first place in Japan you could get it. 

Anyways, I was listening to the song Peking Duck by Haruomi Hosono the other day ( [https://www.youtube.com/watch?v=HxvKkxV1bw4&list=RDHxvKkxV1bw4&start\_radio=1](https://www.youtube.com/watch?v=HxvKkxV1bw4&list=RDHxvKkxV1bw4&start_radio=1) ), and something about it struck me. The song itself is a very pretty lush exotica/pop, but the lyrics are surprisingly violent and depict Yokohama Chinatown burning down. Hosono said in an interview that the inspiration was "Peking Duck" by Fujiko Fujio (creators of Doraemon), which is a horror/humor short story where <SPOILERS> the ending depicts human's being fattened up and prepared like Peking Duck.

I started searching for places where Peking Duck and Yokohama are used as a really prominent metaphor a/o motif etc, and theres probably a lot that I'm missing, but all I could come up with is Like a Dragon and Peking Duck by Haruomi Hosono (and by extension Peking Duc by Fujiko Fujio). 

The coincidence here is that both Kiryu and Ichiban have ended up being bound and hung from the ceiling like a human Peking Duck, and on both occasions it happened in Yokohama, and from what I remember those are the only times anyone in the series is tied up that way. The way Majima gets tied up in Yakuza 0 for a moment is similar, but his chains are attached to the walls and not the ceiling, so he isn't hanging.

No lore implications whatsover, but I thought it was funny!

Funny coincidence with Peking Duck
