Around 80 percent of surveyed single working people in Japan, both men and women, often spend their days off alone, an online survey by Citizen Watch Co. has found.

The survey conducted in late September covering 400 single full-time employees in their 20s to 60s showed that 58.3 percent of respondents spent their days off alone at home while 21.8 percent went out alone during their holidays.

"The finding showed people's tendency to become 'inward-looking' as they appreciate time to themselves," an official of the Tokyo-based clock maker said.

The survey also showed 16 percent of respondents often went out with someone on their days off, while 4 percent said they tended to stay at home with someone.

To the question of what activities they place priority on during their time off, 48.5 percent, or the largest proportion of respondents, said they prefer to "get some sleep."

Some 33.3 percent said they prefer to check "internet and social media," and 32.8 percent preferred to "watch TV." Multiple choice answers were allowed in the questionnaire.

Some 10.5 percent said they prioritize spending time with friends and acquaintances and 9 percent said they prioritize time with their boyfriends or girlfriends.

The survey found that respondents traveled within Japan on average 2.22 times during the past year and visited their parents' home 1.31 times.

The average number of times over the past year that respondents went to a matchmaking party was 0.44 and to a marriage-hunting party 0.34.
