Without Japanese, most people keep working time.
「why Japanese work a lot?」
In my opinion, this is 「the Japanese culture」.
After World war Ⅱ, Japanese economy was falling down. Japan was poor country at that time.
Japan need innovation, so they worked as hard as they can. Since they worked a lot, they believed that need of the day is to promote the development of industries. Japanese worked a long time one day. After that, Japanese economy develop at high speed. they believed that working overtime is the way to success life.
However, this idea is old.
The modern time, the person who gets a lot of information early, makes time management is winner, I think.
The time of the day is limited. We need to think of how to use the time effectively.
If I were prime minister in Japan, I would make holiday for one month for working people, and make time management class in school, increase English class lol
Work life balance is important.
I hope that all Japanese will be happy with good work life balance.
