Diana is young and uneasy in a new relationship when she leaves America and moves halfway around the world to Tokyo seeking adventure. In Japan she takes a job as a nanny to two-year-old Yuki Yoshimura and sets about adapting to a routine of English practice, ballet and swimming lessons, and Japanese cooking.

But as Diana becomes increasingly attached to Yuki she also becomes aware that everything in the Yoshimura household isn't as it first seemed. Before long, she must ask herself if she is brave enough to put everything on the line for the child under her care, confronting her own demons at every step of the way.

Yuki Means Happiness is a rich and powerfully illuminating portrait of the intense relationship between a young woman and her small charge, as well as one woman's journey to discover her true self.
