I don't know if this is a nod to a doll in Japan or not,
this is just my theory,but I was looking up supposedly haunted dolls one night and one caught my attention the most.
Okiku doll its a famous legend across Japan that is supposed to be haunted by a spirit of a little girl who played with it.
According to the temple where the doll now resides in since 1938,Mannenji temple in the town of Iwamizawa,
it used to have short cropped hair,but over time it has grown to about 25 centimeters (10 in) long, down to the doll’s knees.
Although the hair is periodically trimmed, it reportedly keeps growing back.
Do you think that maybe they put in Okiku in Fatal Frame III?
I thought that I would share this with you guys,I thought it was actually kind of neat.
here's the link of a video explaining the story about the doll and where it came from.
