Document 72 Hours - Season 4 Episode 7 Enthusiastic Singing! Hitori Karaoke
8.70 30 minutes Hitorikara" is the art of singing karaoke alone. Recently, specialty stores have also appeared. At a 24-hour restaurant in Shinjuku, Tokyo, 48 private rooms are available, and on weekends there is a long line of people waiting for their turn to sing. What are they trying to get rid of by singing? Young people who want to sing enthusiastically without worrying about others. Housewives who are busy raising children or working part-time. College students job hunting or looking for a new job. This is a microcosm of repeated “struggles” of people seeking a place where they can be at ease and take a step toward tomorrow by singing.
