Generation 5 was worse, we finally got out of Japan, but their starters didn't represent American culture at all, Samurott yells Japan more than all the first four generations.
It was until France that the Starters began to better represent the culture of their region, in this case with Delphox and Chesnaught.
In Hawaii the only one that carries the Hawaiian culture is Decidueye, based on the folklore of their ghosts and ancestors.
In England, the subject is better worked with sports, music, and English cinema as a reference (despite using species not typical of real England)
In short, only France and England are referenced in this way for having a well-constructed national identity, the rest are mishmashes without any meaning or that require digging very deep to connect them with their real location counterpart. For example you see Feraligatr and none of its design screams Kansai at you, just the opposite with Hisui's starters.
