Infant mortality in Japan, 1920-2020

The infant mortality rate in Japan, for children under the age of one year old, was 166 deaths per thousand births in 1920. This means that for all babies born in 1920, just under 17 percent did survive past their first birthday. This rate decreased gradually and consistently over the next century, and today, Japan has one of the lowest infant mortality rates in the world, with approximately 99.8% of all babies surviving past their first birthday.
