U.S. Ambassador Caroline Kennedy has traced the woman who sent her father, President John F. Kennedy, a set of elaborate "hina" dolls in 1962.

Kennedy appealed for help in finding the sender of the dolls, which she played with as a child and which are on display at the ambassadorial residence in Tokyo in the run-up to the Girls' Day festival on March 3.

The dolls were sent by former grocer Tsuyako Matsumoto, now 92 and living in a nursing home in Kitami, Hokkaido Prefecture.
