Japanese Prime Minister Shinzo Abe and fellow leaders of the Group of Seven advanced economies will begin their summit Thursday with a visit to Ise Shrine, the most hallowed site for Japan's indigenous Shinto religion - one of many aspects of the gathering that dovetail with Abe's long-term diplomatic and political agenda. As host, to the extent that it can, Abe's government has shaped the G-7 program to showcase his own political and economic platform, taking "leadership in guiding the world by showing the best path forward for peace and prosperity," according to an agenda distributed by the Foreign Ministry.
