Grandfather’s Journey (1993) by Allen Say.
With gorgeous paintings and a sparse story-telling style, this book is a window onto the journey of a Japanese immigrant to the United States in the late 1800s/ early 1900s. Say does an especially good job capturing the experience of kids and people who have grown up in two cultures.
"After a time, I came to love the land my grandfather had loved, and I stayed on and on until I had a daughter of my own. But I also miss the mountains and rivers of my childhood. I miss my old friends. So I return now and then, when I can not still the longing in my heart. The funny thing is, the moment I am in one country, I am homesick for the other." True for Say himself, as it was likely true for his grandfather.
