Fushimi Inari Taisha

The torii (gate) has a special role in Shintoism, usually marking the entrance to the holy grounds of shinto shrines. Quoting Wikipedia: "As hinted by the kanji (鳥 tori: bird; 居 i: place), a torii is designed for birds to rest. This is because in Shintoism, birds are considered messengers of the gods."

The Fushimi Inari Taisha (or shrine) in the south-eastern outskirts of Kyoto, is world famous for its thousands of torii. From you enter at one end, you can stroll something like 6-10 km before you have gone through them all. It's a cool experience, and the view from the hill the path climbs, you get a good view of southern Kyoto. Yet another great sight in the cultural captial of Japan.
