TOKYO (Kyodo) -- Nearly half of full-time workers in their 20s in Japan engage in "oshi-katsu" activities in support of their favorite pop idols, anime characters and sports stars, a recent survey by Japanese recruitment company Mynavi Corp. showed, with the results also suggesting such activities could help boost motivation at work.

The growing trend of oshi-katsu, which includes purchasing merchandise, attending events and posting online, is likely driven by an increased emphasis on leading a fulfilling life and the widespread use of social media, a Mynavi representative said.

The survey conducted online in October targeted permanent employees in their 20s to 50s across Japan, with valid responses received from around 20,000. Across all age groups, 28.5 percent of respondents said they participate in oshi-katsu.

The proportion was highest among those in their 20s at 49.2 percent, followed by those in their 30s at 33.7 percent. The rate dropped to 22.6 percent for those in their 40s and to 15.5 percent for those in their 50s.

The most commonly supported category was "idols," followed by "anime and anime characters" and "athletes and sports," according to the survey.

Respondents on average spent just over 13,000 yen ($84) per month on "oshi-katsu," with those in their 30s spending the most at 14,692 yen.

Nearly 80 percent of those who engage in such activities said it makes their personal life more fulfilling, while over 60 percent said it provides motivation to work harder at their jobs.

Some companies have even introduced programs to support their employees' oshi-katsu activities. A related survey of mid-career hiring managers found that paid wellness leave and free tickets to sports games were among the initiatives in place.
