This work has been released into the 公有領域 by the author on Flickr, where the author has declared it as a "Public Domain Work" and tagged it with the 創用CC Public Domain Mark.

The 公有領域標識 (PDM) is not a copyright license, but a symbol used to indicate that a work is in the public domain. When it is applied by the author or the copyright holder, community consensus has decided such works as being public domain in the US and countries where it is legally possible to release own work to the public domain. In the countries where this is not possible, the copyright status of the work remains undetermined.

If a file is tagged with Public Domain Mark by someone other than the author or the copyright holder, a more specific copyright tag such as one found at Commons:Copyright tags/General public domain must be applied. If this is your own work, please use {{Cc-zero}} instead.
