Modern Publishing in Japan

日本出版百年史年表
Fabulous online chronology that lists major events in publishing history, titles, and what was happening in the world at the same time.

Copyright

In general, copyright protections extend 50 years beyond the death of the author in Japan and 70 years beyond the death of the author in the United States. Copyright protections may be extended or sold as well.

Guidance from the NDL on finding out author's death date
You would think that information about books would be easy, but it isn't. There used to be an annual publications called 著作権台帳 published in print. It has ceased publication. Now you need to check the author's dates in NDL OPAC, the name listed on the colophon, and check with publishers.
