Example of a hospital's advice on post partum care in Japan.
Support group for during pregnancy in the Kanto region
Surviving in Japan. I found some of the information to be very biased, but it is a good start for women who are looking for resources about pregnancy in Japan. ☆Disclaimer: one article suggests that any foreign woman in Japan should expect the Doctor to comment on her weight gain during pregnancy. This has not been my experience at all. My hospital has never commented on my weight gain on any pregnancy and it is above the "Japanese average".
