Article 2 of Japanese copyright law defines that a work is eligible for copyright when it is a production in which thoughts or sentiments are expressed in a creative way and which falls within the literary, scientific, artistic or musical domain. Japanese courts have decided that to be copyrightable, a text logo needs to have artistic appearance that is worth artistic appreciation. Logos composed merely of geometric shapes and texts are also not copyrightable in general. See COM:CRT/Japan#Threshold of originality for more information.
Note: if the screenshot shows any work that is not a direct result of the program code itself, such as a text or graphics that are not part of the program, the license for that work must be indicated separately.
