How about joining the project for peace, “Kids' Guernica in Hiroshima 2015”?
Pablo Picasso created "Guernica" to protest against the brutality of bombing during the Spanish civil war in 1937. He painted "Guernica" on a canvas (3.5m x 7.8m). It is one of the most famous pictures for peace to protest against war. Kids' Guernica is a global movement of art in which children paint pictures of the same size as Guernica as Picasso did for peace.

Kids’ Guernika in Hiroshima 2015 is a part of this global movement. Children in Hiroshima are going to collaborate with many people around the world who also hope for peace. They will
create their art, “Kids’ Guernika” together. They will exhibit the murals in Hiroshima Peace Park and in some other buildings around the park.
The exhibitions for this project will be held many times in and out of Japan, starting from July 24 to 27 at the bank which faces the Atomic Bomb Dome over the river in Hiroshima Peace Park. The murals will be exhibited in an international exhibition in Ubdo, Bali Island, Indonesia from August 11 to 19. An international exhibition of Kids’ Guernika is being planned in Guernika City in Spain. The murals will also be sent to this exhibition.
One of the aims of this project is that children can learn the importance of mutual understanding through international exchanges through collaboration to create art for peace. The entries of “Youth Messages for Peace” will be parts of the collaboration. This project can also offer an opportunity for schools, organizations for local children, and communities to promote better human relations.
