The composition of coats of arms are generally public domain with respect to copyright laws, and may be reproduced freely.
This corresponds to the international traditional usage, and is explicitly stated in some national copyright laws. Some compositions, of more recent origin, may be copyrighted.
This is not a valid license as such, being a "public domain" statement for the coat of arms definition only. It must be completed with the copyright tag associated to the picture creation.
Please note that this applies only to the coat of arms definition (composition / description). The representation of a coat of arms is an artistic creation, subject as such to copyright laws.
Restriction of use - Legal notice: Most of the time, the usage of coats of arms is governed by legal restrictions, independent of the status of the depiction shown here. A coat of arms represents its owner. Though it can be freely represented, it cannot be appropriated, or used in such a way as to create a confusion with or a prejudice to its owner.
Usage on Commons: Please provide licence information for the coat of arm representation, information for the author of the picture, and the source if not self-made work.
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 Unpublished works need to satisfy {{PD-US-unpublished}}.
