This article explores the sleeping habits of the Japanese population and how many hours they typically sleep each night. It was found that the average amount of sleep for adults aged 20-64 was 6.8 hours per night, however younger generations are getting even less sleep than their parents or grandparents did when they were growing up in Japan. Factors affecting sleep quality include lifestyle choices such as diet, exercise habits, and alcohol consumption as well as environmental factors like noise pollution or bright lights from electronic devices late at night. In order to improve sleep quality, people should avoid screens one hour before bedtime, exercise regularly, stick to a regular bedtime routine, and avoid caffeine late afternoon/evening.
