Empress Michiko, marking her 80th birthday Monday, expressed hope that peace can be brought about by removing sources of conflict ahead of the 70th anniversary next year of the end of World War II.

War-bereaved families have "consistently engaged in activities aimed toward a peaceful world, free of war," the Empress said in a statement, referring to the many sacrifices and difficulties experienced by the public during and after World War II.

"It is important for all of us today who are enjoying the benefits of peace to continue to make every effort to nip the buds of conflict and suffering both in Japan and abroad, and to always aspire strongly toward peace in the world," she said.
