The Okiku doll of Mannen-ji
Mannen-ji temple in Iwamizawa, Hokkaido, keeps a doll whose hair is said to keep growing; the family that owned it left it there in 1938.
1938 CE · 43.20, 141.78 · status: claim
The account
The story says a boy bought the doll in 1918 for his little sister Okiku, who died soon after, and the family took the growing hair as a sign of her spirit. Monks trim it from time to time.
The sceptical view
Accounts conflict on dates and details; hair glued into a doll can shift and appear longer, and the story has not been tested independently.
