Kurosawa autobiography rights

I have been reading Something Like An Autobiography and it seems a really good book. I am thinking about publishing a translation, but I can’t find who owns the rights. My edition is from 1983 and it says Kurosawa himself owns the copyright. I can’t find any edition published after his death to see who owns the rights now.
Can anybody help?
Thank you!

Hi Baumann!

I assume that it’s the Kurosawa estate that you should contact. I just sent you an email (to the address that you used when registering to this website) with more information.
