Abe laid wreaths at various cemeteries and memorials Monday ahead of a visit to the site of the 1941 bombing that plunged the United States into World War II. The USS Arizona Memorial at Pearl Harbor was closed to the public Tuesday when Abe visited the historic site, joined by President Barack Obama, who is vacationing in Hawaii with his family.
