This article examines the reasons why Japanese people typically wake up early, the differences between waking times in Japan and other countries, and the recent changes in Japanese waking times due to technology and other factors. It is largely attributed to cultural norms around punctuality and practical considerations like work schedules, transportation schedules, and working hours. Recent technological advances have seen a shift towards later waking times among younger generations of Japanese people. However, individual preferences still play a big role in determining when a person wakes up each day.
