This is the Meiji Shrine, located next to Harajuku, built in 1920 to commemorate Emperor Meiji. He was the first emperor of modern Japan, having regained power back from the Shoguns in 1868. It was he who pushed Japan from a feudal country into the modern westernized country that it is today. He was the emperor in "The Last Samurai" who finally defeated all the traditionalist warlords with modern weapons. He died in 1912.
