When I searched examples of Torii, some were incredible and very beautiful.
Torii means "birds perch" but this was changed for "pass and enter". In this religion the birds were seen as messengers of the gods. It became a symbol of prosperity and good luck.
This began to be very important that all Japan has Toriis. Usually found in the entrance of the Sanctuary of Japan.
There are formed by two columns on a table. Usually is red or black.There are usually made of wood, stone or steel. Some are so long that form tunnels.
A famous Torii is found in Fushimi Inari, Kyoto. A simple and ancient Torii is in Kasuga-Taisha.
For Buddhist, torii, represented a religious shintoist symbol.
