Five-year-old Lani, adopted in infancy from Japan, lives with her Hawaii mixed-race family. Though festive, her adoption day celebration brings Lani's focus to an ongoing concern: Has my mother in Japan forgotten me? Lani seeks reassurance that her birth mom remembers-both her and her special day. Realizing the depth of Lani's perturbation, knowing it can affect their relationship both now and in the future, her family finds ways to put to rest her worries, while emphasizing Lani's importance to their family. Using a book she has received as an adoption-day gift, Mommy, Daddy and sister Vivi help Lani learn about her Japanese heritage, pointing out that her adoptive Hawaiian family is mixed-race, a positive example of modern-day diversity. With her worries soothed, Lani dreams that night of the meeting/melding of Japanese and Hawaiian-American cultures.
