Understanding Japan's Population

Japan is the 12th most populous country in the world, with an estimated population of 123,800,000 people as of today. This figure is an estimate — it starts from the most recent official count and advances second by second using Japan's annual growth rate of -0.53%.

The population is declining. At the current rate, Japan adds or loses roughly 1,798 people per day. With a land area of 1,000,000 km², it is densely populated (124 people per km²).

The "Births Today" and "Deaths Today" figures are estimates based on annualized rates prorated to the time elapsed since midnight. The age and gender distribution reflects the most recent demographic profile available. For how these figures are computed, see our Methodology page.
