South Korean President Yoon Suk-yeol will arrive in the western Japanese city of Hiroshima on Friday to meet Japanese Prime Minister Kishida Fumio and other leaders of the Group of Seven countries.
Yoon will stay for three days in Hiroshima with his wife, Kim Keon-hee. The G7 summit takes place from Friday through Sunday.
Yoon will attend discussions with the leaders of G7 countries and regional groups. He will meet Kishida on Sunday. Arrangements are underway for a three-way summit with Kishida and US President Joe Biden.
Yoon is expected to take up issues such as North Korea's nuclear and missile development, as well as supply chains for semiconductors and other vital products.
Yoon is scheduled to join Kishida on a visit to a monument dedicated to Korean victims of the 1945 atomic bombing of Hiroshima. He will become the first South Korean president to pay tribute at the monument, which stands in the Hiroshima Peace Memorial Park.
It is said tens of thousands of people from the Korean Peninsula were killed in the bombing, although the exact figure remains unclear.
Yoon met Kishida in Tokyo in March, and in Seoul earlier this month.
Critics in South Korea oppose Yoon's approach to pursuing better relations with Japan. But his planned visit to the monument with Kishida is believed to be an effort to show their desire to advance bilateral ties with a view to the future.
