See Osaka, Japan's second largest city, and home to beloved historic sites, plus ancient weaponry and relics displays. Begin at Osaka Castle. Built in the 16th century by Toyotomi Mideyoshi, the warlord who then controlled Japan, it offers extensive displays of weapons, armor, and folk life relics of that era. Then visit ancient Sumiyoshi Taisha Shrine. The head of over 2,000 Sumiyoshi-sha shrines nationwide, it draws some 3 million people each New Year. Its sanctuaries are designated national treasures.
