The Treaty on the Prohibition of Nuclear Weapons was adopted at the United Nations Conference by 122 affirmative votes with one opposition and one abstention on July 7, 2017. The Treaty was open for signature from September 20, 2017. The initiative for this treaty emerged from international civil society groups and many non-nuclear-weapon states that supported the idea. The conference to negotiate a treaty was held in 2017 to successfully conclude a treaty through the collaboration of these two groups and states, after a discussion held at the United Nations on this issue in 2016. This paper first examines the background and negotiation process, then surveys the content of the treaty as a central issue, next introduces opposing opinions and clarifies the significance of this treaty, and finally points out future challenges.
