What are those red gates standing everywhere — sometimes in the sea or deep in the mountains?
Vermilion gates called torii stand at shrine entrances, but also alone on mountainsides, on rocks, in the sea (Itsukushima), and in tunnels of thousands at Fushimi Inari. Maps mark shrines with a torii symbol, and tiny torii even appear painted on walls in back alleys.
A torii marks the boundary where the ordinary world ends and a kami's domain begins. Passing through one means entering sacred space — which is why they stand wherever a kami is felt to dwell, not just in front of buildings.
Why — five layers
In Shinto, kami dwell in nature itself — mountains, waterfalls, giant trees, the sea. A gate with no wall is the perfect marker for a boundary that is spiritual rather than physical.
Donating a torii is a traditional act of gratitude for answered prayers. The thousands at Fushimi Inari are individual donations from businesses and families, each inscribed with the donor's name — the tunnel is centuries of accumulated thanks.
International view
Sacred gateways exist elsewhere — China's pailou, India's torana — but a freestanding gate with no wall, marking invisible boundaries even in open water, is distinctively Shinto.
But not always
Not every torii is vermilion — stone, plain wood, and white ones are common. And a mini torii painted on a wall is often just an anti-littering trick that borrows the 'don't defile sacred ground' reflex.
What to do
Walking through is welcome. A light bow before entering is polite, and locals tend to avoid the exact center of the path — traditionally the kami's route. Photos are fine at almost all shrines.
