The document discusses Japanese royalty and tradition over two periods - the Meiji era from 1868 to 1912 and the post-World War II period. During the Meiji era, Emperor Mutsuhito centralized power by removing the authority of shoguns and clan leaders, transforming Japan into a modern liberal society. In the post-war period, General MacArthur opted to preserve the Japanese monarchy to help reforms and prevent instability, using Emperor Hirohito as a symbol of stability for the Japanese people during the American occupation.
