Japanese Prime Minister Suga Yoshihide will leave for Britain on Thursday to attend the Group of Seven summit chaired by his British counterpart, Boris Johnson.
The meeting will be held in Cornwall in southwestern Britain from Friday to Sunday. It will be the leaders' first face-to-face G7 summit in two years.
They plan to discuss the coronavirus pandemic, climate change, as well as economic, trade and regional issues. They will also exchange views on support for developing countries to ensure fair vaccine supply.
Another topic is expected to be a coordinated response to China, which is increasing its presence in the East and South China seas.
Arrangements are being made for meetings between Suga and the leaders of Britain, France Germany and Australia, which has been invited to the G7 meeting as a guest country.
