If you've watched Memoirs of a Geisha, there is a scene where Zhang Zhi Yi is running through a series of gates after stealing the green destiny sword or something like that. These gates are located n Kyoto. I suspect that the colors of the gates were heightened because walking through them they appeared worn over time.
On the way to the gates there are a series of shrines which you can make prayers at and place donations.
The path through the gates is approximately 4km long and will take you about 2 hours to move through since it is all uphill. The heat was brutal that day so my family and I opted for ice cream instead.
At one point the path diverges into two but they don't go very far before they reunite.
This is the reverse view. I believe the etchings are records of groups that have passed through the gates. It was a pretty interesting place to visit and I'm disappointed I didn't get to see the whole thing. I would definitely like to come back during the winter, spring, or fall and go through the entire path.
