According to a recent survey by Citizen Watch, the share of Japanese working adults who sleep five hours or less per day was 11.5%, about half as much as 25 years ago.
In the 1999 survey the share of these people was 22.8%.
The Ministry of Health recommends adults get at least six hours of sleep. The company, which published the latest research results on Thursday, believes that sleep deprivation has been reduced thanks to the correction of long working hours and the spread of flexible working styles.
In the April Internet survey of 400 working people between the ages of 20 and 50 across Japan, 36.3%, or the largest group, said they sleep for six hours, followed by 36.0% who said seven hours to sleep.
The combined percentage of respondents who said they slept seven hours or more was 52.4%, a significant increase from 27.0% in 1999, but still less than 67.6% in 1974.
When the company asked 200 married people how long they talked to their partners, 15.5% said they spent at least two hours, more than double the 6.4% in 1999 and the 6.9% in 1974. promoting work style reforms and the COVID-19 pandemic, people may be spending more time at home with their families,” the company said in a report of the survey.
On the contrary, the percentage of people who do not have time to talk to their partner has risen from 10.2% in 1999 and 0% in 1974 to 12.0%, apparently reflecting an increase in the number of dual-income households.
