The Inner shrine is actually a complex of 4 or 5 buildings. The first shrine is veiwable by the public, the second shrine is veiwable by those who pay a very large fee, usually large companies, to be blessed. The shrines beyond that are off limits to anyone but the High Priests and the Emporer. The reson for this is that in one of those shrines is the Bronze Mirror one of Japan's Three Sacred Treasures. This is the second shrine from right outside the complex.
