According to Japanese Copyright Law (June 1, 2018 grant), the work is now in the public domain in Japan because the copyrights of the works in names of organizations, in Japan expire in 50 years after the publication, or in 50 years after the creation if the works are not published within 50 years after the creation (article 53).
To uploader: Please provide a name of organization and year of publication and source.
Note:The enforcement of the revised Copyright Act on December 30, 2018 extended the copyright term of works whose copyright was valid on that day to 70 years. Do not use this template for works published after 1967.
Please note that being in the public domain in Japan does not automatically mean that it is free as well in the United States. Find and add one of the PD US license tags in order to ensure that the file is free in the United States. Typically, for a published work to be in the public domain in the United States, it needs to be published before 1946, because of URAA-restored copyrights. Unpublished works need to satisfy {{PD-US-unpublished}}.
This file is now in the public domain in the Republic of China (Taiwan) because its term of copyright has expired there. According to articles 30 to 34 of the copyright laws of R.O.C., under the jurisdiction of the Government of R.O.C. all non-photographic works enter the public domain 50 years after the death of the creator (there being multiple creators, the creator who dies last) or 50 years after publication for anonymous or pseudonymous authors or for works whose copyright holder is an organization; photographic works enter the public domain 50 years after the public release.
Important note: Works of foreign (non-U.S.) origin must be out of copyright or freely licensed in both their home country and the United States in order to be accepted on Commons. Works of Taiwanese origin that have entered the public domain in the U.S. due to certain circumstances (such as publication in noncompliance with U.S. copyright formalities) and which were under copyright in Taiwan on January 1, 2002 may have had their U.S. copyright restored under the URAA.[1]
