In Japan, the birth rate has hit a 10-year mark as the lowest, continuing a demographic trend that has been on-going for 25 years. In 2021, there were only 670,000 births registered, marking a significant fall in the country's population. These statistics raise more worries about the economic implications of Japan’s rapidly aging society and shrinking labor force.

In Japan, the low birth rate scenario is a significant societal concern. This situation heavily impacts its economic growth, pension system, and healthcare facilities. Demographically, Japan is seen as a 'super-aged' nation, where more than 20% of people are over 65. A declining birth rate is leading towards a shrinking workforce and an increasing number of senior citizens, putting pressure on social security expenses and younger generations.

Contrarily, in the U.S and EU, while birth rates have also been seeing a decline, the situation is not as severe. Immigration plays a big role in the addition to their populations, something Japan, with its strict immigration policies, lacks. These regions also have more significant measures and policies in place to support families with children in order to encourage higher birth rates.
