Where do most writers get their ideas? For Yoshiko Uchida, it all began with Brownie, a five-month-old puppy. So excited was Yoshiko by Brownie’s arrival that she started keeping a journal, writing about all the wonderful things Brownie did and the progress he made.

Soon she was writing about other memorable events in her life, too, like the day her family got their first refrigerator. She also began writing stories, thanks to one of her teachers. Yoshiko wrote stories about animal characters such as Jimmy Chipmunk and Willie the Squirrel. She kept on writing, sharing the kitchen table with her mother, who wrote poems on scraps of paper and the backs of envelopes.

Yoshiko grew up in the 1930s in Berkeley, California. Her parents, both of whom had been born in Japan, provided a loving and happy home for Yoshiko and her sister. They also provided a stream of visitors to their home who later found their way into Yoshiko’s stories. One visitor who later appeared in several of Yoshiko’s stories was the bad-tempered Mr. Toga, who lived above the church that her family attended. Mr. Toga would scold anyone who displeased him. The children all feared him and loved to tell stories about how mean he was and how his false teeth rattled (咯咯响) when he talked.

Yoshiko also included in her stories some of the places she visited and the experiences she had. One of her favorite places was a farm her parents took her to one summer. The owners of the farm, showed Yoshiko and her sister how to pump water from the well and how to gather eggs in the henhouse. They fed the mules that later pulled a wagon loaded with hay while Yoshiko and the others rode in the back, staring up at the stars shining in the night sky. Yoshiko, who lived in the city, had never seen such a sight. As Yoshiko gazed up at the stars, she was filled with hope and excitement about her life. The images of that hayride stayed with her long after the summer visit ended, and she used them in several of her stories.

The experiences Yoshiko had and the parade of people who marched through her young life became a part of the world she created in over twenty books for young people, such as The Best Bad Thing and A Jar of Dreams. Because of such books, we can all share just a little bit of the world and the times in which this great writer grew up.
