This interdisciplinary monograph is the culmination of long-term theoretical and ethnographic research and is an important contribution both to the history of migration of Japanese labourers’ families to Brazil, their adaptation to the new conditions, and to socio-ethnographic studies on childhood, coming of age and the formation of family bonds. At the same time, it is an interesting study on the life of international economic migrants from Japan to Brazil, whose children and grandchildren (the next generations of migrants) decided to return to the country of their grandparents’ origin. The author points to the usefulness of ethnographic research in studying the migration of families with children. This type of research enables a more in-depth understanding of the daily lives of the research participants in the conditions of migration and their socio-cultural and geographical identity. Importantly, it also indicates paths for the exploration of interdependencies between history and childhood biographies in societies with the second and third generation of migrating migrants.
