Nothing in Japan from what I could find here or elsewhere… don’t understand why
edit: thanks to the dead commenter for clarifying. that sucks.
Note that the copyright is not about the source country of the work, but where do make/distribute the copy. Do you live in Japan, or are you interested in Japanese works? (Or both, possibly.)
The "TPP11," which includes a provision to extend the term of protection to 70 years, will enter into force on December 30, 2018.
In Japan, the term of copyright protection will, in principle, be 70 years after the death of the author (or 70 years after publication for works published anonymously, under a pseudonym, or in the name of a corporate body).
Copyrights that have already expired at the time of enforcement will not be revived (principle of non-retroactivity of protection).
Consequently, no works will newly enter the public domain for the next 20 years.

I’m adding a one-act Tanizaki play to Standard Ebooks’ Tanizaki collection[1] on the 1st January. Some Akutagawa shorts go into US public domain next year too. (Note: copyright is based on the translation date, not the original language.)
