The Japanese government on Thursday set up a board at the prime minister's office in Tokyo to mark the countdown to the Group of Seven summit in May in Hiroshima with 134 days to go.
A kickoff ceremony for the countdown was attended by Prime Minister Fumio Kishida, who aims to build momentum for the May 19-20 summit as a lawmaker representing a constituency in the western Japan city, devastated by the 1945 U.S. atomic bombing.
Kishida said he wants to lead debate at the gathering so the G-7 leaders can deepen discussions and present their visions and messages for the future.
Noting that related ministerial meetings will be held in more than 10 locations throughout Japan, the prime minister said the summit "will be a very valuable opportunity to show the world the attractions of each region in Japan."
The G-7 groups Britain, Canada, France, Germany, Italy, Japan and the United States, plus the European Union.
On Wednesday, Kishida said at a press conference that he will pitch his vision of a world without nuclear weapons at the gathering.
