10160 Totoro           Discovered 1994 Dec. 31 by T. Kobayashi at Oizumi.
Hayao Miyazaki produced the animated movie My Neighbor Totoro in 1988, featuring the fairy Totoro. Through the movie, Totoro once again found his place in the hearts of Japanese children, in a time when the woods and darkness where Totoro lives are rapidly disappearing from the earth.
