Japan is a country where ancient tradition and hyper-modern innovation coexist with a seamlessness that seems impossible until you experience it, from the temples and zen gardens of Kyoto to the neon-lit streets of Tokyo and the mountain shrines of the Japan Alps. The culture is one of extraordinary attention to craft, detail, and hospitality, expressed in everything from a bowl of ramen to the design of a train station. It suits almost every kind of traveller and consistently ranks among the most memorable places people have ever visited.
Japan's Human Development Index is 0.925 for 2023 (UNDP Human Development Report 2025), ranked #23 of 193 by UNDP.
Japan scores 1.49 on the Global Peace Index (lower is more peaceful), ranked #10 of 161 countries by the Institute for Economics & Peace. That measures national-level peace, not street crime; both are covered below.
Numbeo's cost-of-living index puts Japan at 47.5 (New York = 100); that is #89 cheapest of 143 countries with data.
Life expectancy at birth in Japan is 84.0 yrs (World Bank), ranked #9 of 195 countries.
Numbeo's quality-of-life index scores Japan at 185.6, ranked #17 of 87 countries with data. It composites purchasing power, safety, healthcare, cost of living, commute and pollution from resident surveys, so it reflects what residents report rather than what an economy produces.
