Sa sobrang timid ng mga Japanese, kahit 'yung mga personal problems nila they hardly share it to anyone. They'd rather keep it to themselves. My mom, who lives in Japan, would always kiddingly say that most Japanese die of sama ng loob/pagkimkim ng problema.
Kaya huge hit palagi sa kanila ang mga KTV, comedy shows, magic tricks, and other variety shows para kahit for a few hours makapag-relax man lang sila. Masyado kasi silang workaholic and they're a bit emotionally sensitive. May neighbor kami before na high school student who committed suicide because he's being bullied in school. Hindi sila kagaya nating mga Pinoy na palaban at maraming outlet. They're the literal example of "school-bahay-school-bahay" teenagers.
Not that I'm generalizing, I'm just saying what I've noticed/observed with my neighbors and what I see in the news.
