King Records will release Mike Leigh's
Naked (1993) on Blu-ray in Japan on May 13th, 2015. As with the
Peter Greenaway Blu-ray Box they are releasing the same day, this is indicated as being "<[Uncensored HD Remastered]>" ("<無修正HDリマスター版>") which should mean the full-frontal nudity in the film will not be optically censored.
So far, the disc has only been listed on Amazon, and no extras are mentioned. I will update if King Records reveals more when they list the disc.
