The Okiku doll has resided at the Mannenji temple in the town of Iwamizawa (Hokkaido prefecture) since 1938. According to the temple, the traditional doll initially had 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.
It is said that the doll was originally purchased in 1918 by a 17-year-old boy named Eikichi Suzuki while visiting Sapporo for a marine exhibition. He bought the doll on Tanuki-koji -- Sapporo's famous shopping street -- as a souvenir for his 2-year-old sister, Okiku. The young girl loved the doll and played with it every day, but the following year, she died suddenly of a cold. The family placed the doll in the household altar and prayed to it every day in memory of Okiku.
