Historical chart and dataset showing Japan infant mortality rate by year from 1950 to 2025.
In 2023, the infant mortality rate in Japan did not change in comparison to the previous year. The infant mortality rate remained at 1.8 deaths per 1,000 live births. The infant mortality rate is the number of newborns who do not survive past the first 12 months of life. This is generally expressed as a value per 1,000 live births, and also includes neonatal mortality (deaths within the first 28 days of life).Find more statistics on other topics about Japan with key insights such as total life expectancy at birth, total fertility rate, and death rate.
UNICEF's country profile for Japan, including under-five mortality rates, child health, education and sanitation data.
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.

The child mortality rate in Japan, for children under the age of five, was 363 deaths per thousand births in 1865. This meant that for every one thousand babies born in 1865, over 36 percent did not survive past their fifth birthday. Over the course of the next 155 years, this number dropped drastically. Child mortality reached its lowest point ever in the five year span between 2015 and 2020, at just two deaths per one thousand births. This was the lowest of any country in the world.

JP: Mortality Rate: Infant: Male: per 1000 Live Births data was reported at 2.100 Ratio in 2016. This stayed constant from the previous number of 2.100 Ratio for 2015. JP: Mortality Rate: Infant: Male: per 1000 Live Births data is updated yearly, averaging 2.500 Ratio from Dec 1990 (Median) to 2016, with 5 observations. The data reached an all-time high of 4.900 Ratio in 1990 and a record low of 2.100 Ratio in 2016. JP: Mortality Rate: Infant: Male: per 1000 Live Births data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Japan – Table JP.World Bank: Health Statistics. Infant mortality rate, male is the number of male infants dying before reaching one year of age, per 1,000 male live births in a given year.; ; Estimates developed by the UN Inter-agency Group for Child Mortality Estimation (UNICEF, WHO, World Bank, UN DESA Population Division) at www.childmortality.org.; Weighted Average; Given that data on the incidence and prevalence of diseases are frequently unavailable, mortality rates are often used to identify vulnerable populations. Moreover, they are among the indicators most frequently used to compare socioeconomic development across countries. Under-five mortality rates are higher for boys than for girls in countries in which parental gender preferences are insignificant. Under-five mortality captures the effect of gender discrimination better than infant mortality does, as malnutrition and medical interventions have more significant impacts to this age group. Where female under-five mortality is higher, girls are likely to have less access to resources than boys.
This statistic shows the 20 countries * with the lowest infant mortality rate in 2024. An estimated 1.5 out of 1,000 live births died in the first year of life in Slovenia and Singapore in 2024. Infant mortality Infant mortality rates are often used as an indicator of the health and well-being of a nation. Monaco, Iceland, and Japan are among the top three countries with the lowest infant mortality rates with around 2 infant deaths per 1,000 infants within their first year of life. Generally, the countries with the lowest infant mortality also have some of the highest average life expectancy figures. Additionally, the countries with the highest density of physicians and doctors also generally report low infant mortality. Yet, many different factors contribute to differing rates, including the overall income of a country, health spending per capita, a mother’s level of education, environmental conditions, and medical infrastructure, to name a few. This creates a lot of variation concerning the level of childbirth and infant care around the world. The countries with the highest rates of infant mortality include Afghanistan, Mali, and Somalia. These countries experience around 100 infant deaths per 1,000 infants in their first year of life. While the reasons for high rates of infant mortality are numerous, the leading causes of death for children under the year five around the world are Pneumonia, Diarrhea, and Prematurity.
In 2023, the death rate in Japan remained nearly unchanged at around ** deaths per 1,000 inhabitants. Nevertheless, 2023 still represents a peak in the death rate in Japan with ** deaths per 1,000 inhabitants. The crude death rate refers to the number of deaths in a given year, expressed per 1,000 population. When studied in combination with the crude birth rate, the rate of natural population increase can be determined.Find more statistics on other topics about Japan with key insights such as infant mortality rate, life expectancy of men at birth, and total life expectancy at birth.
