A torii gate is a traditional Japanese structure that marks the entrance to a sacred space, often found at Shinto shrines. It symbolizes the transition from the mundane to the sacred, inviting visitors to enter a spiritual realm. Typically made of wood or stone, torii gates are characterized by their distinctive two upright pillars and a horizontal beam. These gates come in various styles and colors, with the most common being vermilion red, which is believed to ward off evil spirits. The design and placement of a torii gate can vary, but they are often seen in picturesque settings, enhancing the beauty of the surrounding landscape.
