Illustrator Sachiko Yoshikawa moved to San Francisco from Japan in 1988 to study art. Her initial interest in art was jewelry making and then, gradually, graphic design. Later she branched out into mixed media and began creating narrative illustration. Currently, she enjoys creating whimsical and vibrant illustrations using collage and mixed media such as balsa wood, as well as with traditional techniques. Much of her work has been inspired by living and traveling in the United States and abroad. She has lived in Tokyo, California, Arizona, Oregon, Washington and currently, in Wisconsin. She has also lived in Uganda, in East Africa, where she had a group show with local artists at the Uganda National Museum. She has illustrated numerous books for young readers, such as Beach is to Fun, (named Best Children's book of the Year by the Bank Street College of Education) and What is Science? (a finalist in the Children's Science Picture Book category of the 2007 SB&F Prize).
