A torii is the boundary between the human world and the spirit world, normally at the entrance of a Shinto shrine.
The Great Torii at Miyajima Island , usually shown as if floating on the water at high tide, is an icon of Japan.
But at low tide, one can go up close and explore it.
Some people even place coins between the barnacles for good luck.
But I also like the way the Torii peeks above the roofs as seen on the way down from Mount Misen.
Either way, it’s definitely worth a visit when in Japan.
