Demographics of Japan
demographics of country
The demography of Japan is monitored by the National Institute of Population and Social Security Research (IPSS) and Statistics Bureau. In April 2025, Japan's population was roughly 123.4 million people, and peaked at 128.5 million people in 2010. It is the 6th-most populous country in Asia, and the 12th-most populous country in the world.
In 2024, the median age of Japanese people was projected to be 49.9 years, the highest level since 1950, compared to 29.8 for India, 38.9 for the United States and 40.2 for China. Japan has the second highest median age in the world, behind only Monaco. An improved quality of life and regular health checks are two reasons why Japan has one of the highest life expectancies in the world.
The life expectancy from birth in Japan improved significantly after World War II, rising 20 years between 1945 and 1955. As life expectancy rises further, Japan expects to experience difficulties caring for the older generations in the future. Shortages in the service sector are already a major concern, with demand for nurses and care workers increasing.
The fertility rate among Japanese women was around 1.4 children per woman from 2010 to 2018.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Demographics of Japan”, the useful work is to connect “demographics of country” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 25, 2026. The linked authority identifier is Q1124220. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025, 2010, 2024 and 1950.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
