The most photographed torii in Tokyo?
If you google, “torii in Tokyo”, you will find a lot of images from Hie shrine in the results. I don’t know how to confirm the results but whenever I repeat that search, that is what I see, lots of pictures of the same place. Of course you see other places as well, like Nezu and Hanazono Inari shrines which also have very impressive sets of gates too. But I think Hie is king. What about you?
