Japan is a highly developed island nation in East Asia with a population exceeding 123 million as of 2025, making it the 11th most populous country globally. Known for its technological innovation and economic strength, Japan ranks as the world’s fourth-largest economy and remains a key player in global trade and investment, notably as the United States' fifth-largest trading partner and the largest source of foreign direct investment to the U.S. in 2024[1][8].
Japan's history as a modern economic power began after World War II, rapidly transforming from a war-torn country to a global leader in technology, manufacturing, and innovation. It has excelled in electronics, automotive industries, robotics, and precision machinery, with a strong culture of research and development. Japan was ranked 12th in the 2025 Global Innovation Index, reflecting its ongoing commitment to technological advancement and innovation[5].
Despite these strengths, Japan faces significant demographic challenges. It has the world’s highest median age (48.4) and the fastest-aging population, with nearly 30% of its citizens over 65. The low fertility rate (1.2) and shrinking workforce pose risks to sustained economic growth and social welfare systems. Immigration reforms enacted in 2019 aim to alleviate labor shortages by protecting foreign workers' rights[1].
Economically, Japan experienced a slight GDP contraction in early 2025 amid global slowdown and inflation, but private investment, particularly in labor-saving technologies, grew robustly. Consumer spending is gradually recovering, and economic forecasts predict modest growth of around 0.7-1.1% through 2026, contingent on easing inflation and trade tensions, especially with the U.S.[2][3][4].
In governance, Japan scored below the OECD average on the Digital Government Index, highlighting room for improvement in digital public services despite strengths in digital design[6]. Politically, Japan maintains a stable, democratic society with high levels of personal and internet freedom
