How can the copyright owner exercise his/her copyrights?
The copyright owner can exercise his/her work in the form of licensing
for the exploitation of the copyrighted work.
The Copyright Act of Japan provides that, whoever is the initial owner of rights to a work, all or part of the copyrights may be assigned by contract, etc. If all copyrights are assigned, the assignee, or the person to whom the rights were assigned hasbecome the owner of the copyrights. ※Moral rights, being personal and exclusiveto the author, can never be assigned.
Copyright reflects two kinds of interests of the author of a workthat are generally referred to as economic rightsand moral rights.The economic rights (i.e. copyrights)of the author enable him/her to make a living from his/her work. Therefore, the copyright law grants the author of a workthe exclusive right to authorize others to use his/her work under agreed terms and conditions,and to take legalaction against unauthorized uses. Economic rights cover almost all relevant commercial activities using a copyrighted work, from the tangible(physical) reproduction of the workto the transmission of the work on the Internet. Licensing means that anowner of certain copyrightsremains the owner but/and authorizes someone else to exploit the copyrighted work in some forms
of acts covered by the economic rights, generally for a specific period of time. For example, an author (copyright owner)of a novel may grant a license to a publisher to make and distribute copies
of the novel, and, at the same time, he/she may grant a license to a film producer to make a film based on the novel. Licenses may be exclusive, which means that the owner of the copyrights agrees not to authorize any other person to carry out the licensed
acts, or non-exclusive, which means that the copyright owner may authorize
others to carry out the same acts.
As for jointly owned copyrights, under the Copyright Act of Japan,such joint copyrightsmay not be exercised without the unanimous agreement of all theco-owners.
