According to the Mayors for Peace secretariat in Hiroshima, as of January 1, 2016, the number of Iranian member cities reached 812. More than 700 new members joined in 2014 and 2015, which represents the largest single-country increase in two years among all countries. This historical record was achieved by the team at the office for Iranian members of Mayors for Peace, which is based at the Tehran Peace Museum. They achieved this by consistently communicating with all the mayors in Iran and asking them to join our organization. Iran is now home to the second largest number of member cities of Mayors for Peace in the world after Japan.
