2020 Vision
(An Emergency Campaign to Ban Nuclear Weapons)
Projects
Aiming toward the target year of 2020, Mayors for Peace adopted the “Mayors for Peace Action Plan (2017-2020)” (Overview) at the 9th General Conference held in Nagasaki in August 2017, which set two main objectives that would lead us to our ultimate goal, that of lasting world peace: “Realization of a world without nuclear weapons” and “Realization of safe and resilient cities”. Based on this Action Plan, Mayors for Peace is promoting various projects.
[Main Projects]
- Calling on the UN and national governments to act
- Expanding membership
- Promoting regional activities spearheaded by Lead Cities
- Sharing seeds from A-bombed trees
- The Youth Exchange for Peace Support Programs
- The petition drive calling for all states to join the Treaty on the Prohibition of Nuclear Weapons as soon as possible
- Holding the Mayors for Peace A-bomb Poster Exhibition
- Promotion of peace education
Calling on the UN and national governments to act
Seizing every possible opportunity, including international conferences, Mayors for Peace has called on the UN and governments around the world to support efforts towards the early realization of a legal prohibition on nuclear weapons. These activities and the heartfelt appeal of the hibakusha and many other like-minded people who wish for the abolition of nuclear weapons bore fruit in July 2017, when the Treaty on the Prohibition of Nuclear Weapons was adopted at the UN.
Mayors for Peace will continue to urge all states, including the nuclear-armed states and their allies, to participate in this Treaty as soon as possible. We will also encourage policymakers to work on creating a security framework that moves away from nuclear deterrence and to visit Hiroshima and Nagasaki to share in the hibakusha’s earnest wishes for nuclear abolition.
Expanding membership
We call on non-member cities to join Mayors for Peace, not only through invitations from the President of Mayors for Peace and its Secretariat, but also from other associations of local governments, Lead Cities’ partners and other channels.
Promoting regional activities spearheaded by Lead Cities
Mayors for Peace selects an appropriate number of Lead Cities that take the lead in their regional chapters in order to encourage proactive and independent activities appropriate to each region.
Sharing seeds from A-bombed trees
Mayors for Peace is distributing seeds from A-bomb survivor trees in Hiroshima in response to member cities requests. Please join us in this program by nurturing the trees distributed to your city as symbols of peace, and use them to raise peace consciousness among citizens.
● Requests to Those Receiving the Seeds
Mayors for Peace asks each recipient city to accommodate the following requests:
- 1.To raise seeds/seedlings under the care of experts, such as in botanical gardens, until they become tall and sturdy enough to be planted in the ground.
- 2.Provide the Secretariat with updates on development of the trees at least once a year. These updates should include some information on their height, number of seedlings, growing place and a plan/report of peace activities based around them as well as their photos.
● Procedure to Distribute Seeds
- 1. [Recipient City] Contact the Secretariat
- If a member city wants to receive seeds from A-bombed trees and agrees to accommodate the requests above, please contact the Secretariat by email.
- 2. [Mayors for Peace Secretariat] Conduct preparatory research
-
- a. The Secretariat researches the species of A-bombed trees appropriate for the recipient city’s climate
- b. The Secretariat confirms whether or not procedures for quarantine, export and import licenses are required by the sending country and the receiving country.
- 3. [Mayors for Peace Secretariat] Send a questionnaire to the recipient city
- Based on the preparatory research in 2 - a, the Secretariat enters relevant information into the questionnaire and sends it to the recipient city. If quarantine or an import license is required by the receiving country, the Secretariat informs the recipient city of this information at this point.
- 4. [Recipient City] Return the questionnaire
- a. The recipient city answers the questionnaire by filling in required information, such as tree species they want to receive, intended care facility (e.g. a botanical garden), and contact information, and returns the questionnaire to the Secretariat.
- b. In the case that some procedure is required by the receiving country, the recipient city should contact a domestic quarantine office for their advice on the procedure, then share this information with the Secretariat.
- 5. [Mayors for Peace Secretariat] Send out seeds
- Upon confirmation of the returned questionnaire and the completion of required procedure for quarantine and an import license, the Secretariat sends out seeds to the recipient city. Shipping costs are covered by the Secretariat.
● Note
- When trees from the seeds become tall and sturdy enough to be planted in the ground, the Secretariat can donate an explanatory plaque. Please inform the Secretariat of plans of events involving the tree, such as a planting ceremony. A recipient city can receive one explanatory plaque for each species. If your city wishes to receive the plaque, please let the Secretariat know by at least two months before the desired delivery date.

The Youth Exchange for Peace Support Program
In order to realize a “world free of nuclear weapons,” it is essential to foster and increase international public opinion for it. To this end, Mayors for Peace has implemented programs to encourage and inspire younger generations to get involved in peace activities in the future. These programs provide financial and other support to selected youth from member cities who would like to participate in programs offered by Hiroshima City, Hiroshima City University and so on, to learn about the experiences of A-bomb survivors and their desire for peace.
In each program, in addition to the existing content produced by each host organization, Mayors for Peace conducts its own programs such as a briefing on Mayors for Peace and testimonies from A-bomb survivors.
After completing the program, we ask the participants to propose Mayors for Peace activities for nuclear weapons abolition to their communities and the secretariat of Mayors for Peace. Based on the proposal, each city considers implementing projects. Through our program, we aim at developing human resources and strengthening our member city network.

The petition drive calling for all states to join the Treaty on the Prohibition of Nuclear Weapons as soon as possible
3,111,940 signatures (As of December 1, 2020)
(The above number includes signatures collected through the petition drive calling for negotiations of a nuclear weapons convention Mayors for Peace promoted since December 2010.)
In July 2017, the Treaty on the Prohibition of Nuclear Weapons was adopted at the UN. This was made possible by the heartfelt appeal of the hibakusha and many other like-minded people for the abolition of nuclear weapons. In order for the Treaty to become a fully effective legal instrument for nuclear abolition, we believe it essential for all states, including the nuclear-armed states and their allies, to join this Treaty.
Through this petition drive, let us spread our appeal for peace, which is this path toward a world free of nuclear weapons, and create a powerful movement to urge all states to participate in the Treaty as soon as possible!
