Takachiho Gorge V
At the end of a short, ten minute walk, there are a collection of ramen and udon shops, plus a shrine to some god. Plus these fish.
This is what the sign said there: "Long Ago there was a shrine located here at this pond, and sacred Unotori (comorant birds) served the shring. On the day of the Takachiho Shring Spring Festival, and Omikoshi (portable shring) is carried around the pond three times to be purified."
