Throughout the live action version of Ghost in the Shell, Chief Aramaki spoke only in Japanese the whole time, whereas nearly every other character spoke in English. Is there an in-universe or production reason for this?
From an interview the actor gave to Today Cinema:
"I demanded (to the director) that Aramaki needed to speak in Japanese and I carried it through. Because the based film is a Japanese anime. I was happy to join a film based on a Japanese-born work. But on the technology side, I was amazed by Hollywood.
