This article summarizes the findings of a transnational study of Japanese a
nd Canadian families. Fathers' perceptions are presented for a critical dev
elopmental phase of life: pregnancy, labor, birth, the early and late postp
artum periods. Using qualitative and quantitative research methods, 33 fath
ers and 194 mothers were interviewed: Japanese in Tokyo and Montreal, and E
nglish and French Canadians in Montreal. In addition, the study examines th
e impact of pregnancy and birth on the relationship of marriage. The result
s suggest that the social meaning of fatherhood has been transformed, legit
imizing the presence of the father in the domestic sphere as a consequence
of shifting extended family household structures, economic conditions and t
he empowerment of women. Other significant (p < 0.05) patterns were identif
ied. (1) Canadian fathers participate in labor and delivery to a higher deg
ree than Japanese fathers in Montreal and Tokyo do (mothers in Tokyo felt m
ore isolated). (2) Canadian men (60%) are more likely to take time off from
work during this phase than the Japanese. (3) Overall, the majority of fat
hers, in all four groups, cared for the child to a higher degree than expec
ted and (4). Birth and early child rearing appears to have a significant im
pact on marriage in all four groups. Public policy issues are addressed and
potential responses provided. (C) 2000 Elsevier Science Ltd. All rights re
