Fushimi Inari Taisha
One of the most popular places in Japan is this shrine. A torii gate is a wooden structure that is like a threshold from ordinary lands into sacred lands. While appearing quite old, these gates are actually maintained often, and number around 32,000. Each gate has been donated by a company as an offering to Inari, the god of rice, and, through a somewhat convoluted association, business.
The Fushimi Inari shrine is also known as the Fox shrine, since foxes are thought of as messengers, and are often depicted in japanese artwork as having a key to the rice stores in their mouth, therefore tying into the god Inari.
