In Japan, many young workers in their twenties take part in "oshi-katsu" activities. This means they support their favourite pop idols, anime characters, or sports stars. A survey by Mynavi Corp. found that about 49% of people in this age group do this. The number becomes lower as people get older.

"Oshi-katsu" includes buying merchandise, going to events, and posting online. It is popular because people want a more enjoyable life, and social media makes it easy to connect with others who share the same interests.

People spend around 13,000 yen a month on these activities. Many say it makes their life more satisfying and helps them feel more motivated at work. Some companies now support this by offering wellness leave or free event tickets.
