This document discusses the quality of life (QoL) of Japanese people from both historical and comparative perspectives. It examines objective indices like longevity, GDP, and working hours as well as subjective interpretations of QoL. While Japan's GDP per capita and life expectancy have increased over time, working hours remain long, with unpaid overtime common. The aging population also poses challenges to Japan's economy and pension system. Overall, the document analyzes trends in QoL indicators and debates how to best evaluate Japan's historical and comparative QoL.
