International Campaign to Abolish Nuclear Weapons (ICAN)
The International Campaign to Abolish Nuclear Weapons (ICAN) is a coaliton of 468 non-governmental organizations in 100 countries promoting adherence to and implementation of the United Nations Treaty on the Prohibition of Nuclear Weapons. This landmark global treaty was adopted in New York on 7 July 2017.

ICAN began in Australia and was officially launched in 2007; its main office is based in Geneva. ICAN was awarded the 2017 Nobel Peace Prize "for its work to draw attention to the catastrophic humanitarian consequences of any use of nuclear weapons and for its ground-breaking efforts to achieve a treaty-based prohibition of such weapons".

Strong of its experience working with Hibakusha and other victims and survivors, Peace Boat has been involved with ICAN since 2009 and is part of the International Steering Group. Peace Boat is also playing a key role in coordinating the campaign within Japanese groups and the public.

Since the announcement on 6 October that the 2017 Nobel Peace Prize would be awarded to ICAN, Peace Boat has organized a series of events relating to this renewed momentum towards nuclear disarmament. These included a press conference at Peace Boat centre which several Hibakusha (atomic bomb survivors) attended, a press conference at the Foreign Correspondents' Club of Japan (FCCJ), and press conferences and celebratory events with Hibakusha in Hiroshima, as well as Nagasaki.
