Partners of the leaders of the Group of Seven are due to attend a series of events arranged for them during the 3-day summit in Hiroshima that starts on Friday.
On day one of the Partners' Program at the G7 Hiroshima Summit, the partners are to visit a historical facility in the city to take part in a traditional Japanese tea ceremony.
Kishida Yuko, the wife of Prime Minister Kishida Fumio of summit host Japan, cherishes the tradition.
On the same day, the partners will attend a symposium near the Atomic Bomb Dome, a structure close to the epicenter of the 1945 blast in the city.
The participants, including local university students, are to discuss peace and abolishing nuclear weapons.
The next day, the partners will visit the island of Miyajima just outside Hiroshima City. The island is home to one of the country's most famous Shinto shrines, Itsukushima Shrine, which is a designated national treasure and UNESCO World Heritage Site.
The group will also sample okonomiyaki, an example of local cuisine, and other food made with local ingredients.
On Sunday, they will visit a prefectural museum and Shukkeien, a scenic Japanese garden.
Japan's government hopes the Partners' Program will help make traditional Japanese culture known by people in and out of the country and showcase the charm of Hiroshima as a city of peace.
