Founded in the year 903, like most of Tokyo the shrine is a post war reconstruction. The bombing of Tokyo during World War 2 leveled 16 square miles of the city and therefore most of what you see in Tokyo today is a reconstruction. On the outskirts of Tokyo you are likely to find some original architecture dating as far back as the 13th century. Aside from the war, Tokyo also suffered from the 8.3 Great Kanto earthquake in 1923 which likewise destroyed much of the city.
