Licensing

[edit]
This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain
According to Japanese Copyright Law (June 1, 2018 grant) the copyright on this work has expired and is as such public domain. According to articles 51, 52, 53 and 57 of the copyright laws of Japan, under the jurisdiction of the Government of Japan 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.

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 of the copyright holders who died after 1967.

Use {{PD-Japan-oldphoto}} for photos published before December 31, 1956, and {{PD-Japan-film}} for films produced prior to 1953. Public domain works must be out of copyright in both the United States and in the source country of the work in order to be hosted on the Commons. The file must have an additional copyright tag indicating the copyright status in the United States. See also Copyright rules by territory.

You must also include a United States public domain tag to indicate why this work is in the public domain in the United States.

This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
