It’s the way he used the word samurai that was more confusing than anything. In Night City they were corpo mercs. It may be the case that the Japanese still remembered the ancient ways, but by how Goro spoke of the bakeneko and youkai? Probably not. The yakuza was still very much an active force globally, with V having a few run ins with them in his time.

“I’m familiar with the yakuza. The Kanzaki’s and I are, uh, acquainted.” If you caught his drift.

“You mean like ghosts ‘n shit? Things that go bump in the night?” It’s clear he has some doubts.
