this paper presents a panorama about migration process between brazil and japan. in the beginning of the 20th century, the japanese immigrated to brazil and, in the end of the same century, the japanese descendant brazilians were taken the inverse way: they were going to japan as migrant workers, being well known as "dekassegui". we can call this brazilian？s migration movement to japan as "absence of return". it means, can this populational movement between brazil and japan be considered as "return migration"? we should consider, first, different contexts and contingents.
