Kerry will be the first US Secretary of State to have ever visited the iconic park, where he is set to lay flowers at the memorial dedicated to the victims of the world's first nuclear attack on August 6, 1945.
Japanese Foreign Minister Fumio Kishida said late Saturday: "Foreign ministers from the G7 countries will all visit Hiroshima Peace Memorial Museum and offer flowers at the cenotaph for the victims on April 11."
The visit will take place on the sidelines of a foreign ministers' meeting this month, where the envoys are scheduled to hammer out the agenda for the G7 summit in May.
US officials are still considering a possible visit to Hiroshima by President Barack Obama during his trip to Japan for the meeting, however, no official announcement has been made.
