Does anyone know any good resources for learning about the strange type of Japanese used in period dramas, such as the films of Akira Kurosawa? I recently rewatched Sanjuro, and while at this stage I don’t expect to understand that much Japanese in general, I was surprised by how few words sounded familiar to me at all (except for numerals ). Then I heard from my friend, who is fluent in Japanese and has a Japanese wife, that they had watched Seven Samurai together and they also had trouble understanding the dialogue.
So any ideas on where to find information on the issue? I tried googling for it, but I just found articles about the jidaigeki genre in general. Maybe I wasn’t using the right keywords, I don’t know. I realise this isn’t the aspect of Japanese that I most urgently need to improve, but it would nevertheless be interesting to find out more about it
