I'm posting this to give you an answer on why this happens. My SO is from Hong Kong. His parents were very strict, and he's gone through a lot in his life. Not many people outside of China, Hong Kong, & Japan understand the pressures that society puts on men.
Family reputation is a big thing there. Doing something to make your family look bad is a complete disgrace. So as a man in Hong Kong, China, Japan, you are looked at as the one who has got to pass your family name and reputation along. As a child families usually make you study harder, sign you up for things you might not even like, like piano lessons, and force you to do them. Mistakes you get punished harshly for. Some families even beat their children if the child messes up. (my SO went through this) The community looks at this like it's normal, as long as you don't really hurt the child. You are told all your life you have to study or you will fail. And actually you will fail which is the sad part. Hong Kong at the end of High School, you get a test. You have one chance to pass this test, and if you don't you can't go to the university there. So for people with no money to move to another country, or people who aren't allowed to go to another country that is basically the end of the line for you to get any good job. A lot of the women in Japan are gold diggers, not because they are horrible people, its just how they were raised and taught.. find a man with a good job, and that has money. So there is another reason for a man to feel like he has extreme pressure on him. Also based on how much money you make and the job you have, in your community you can be looked at different.
Also some other things I've learned by just watching which fucking wows me, my SO had to go to china for a month. The whole time he was there he basically was forced to drink. It's just part of the culture in China. Successful men, or men that want a job, are asked to drink. Sure they can turn drinking down, but they are less likely to get the job.. however drinking doesn't mean they have a higher chance of getting the job either... just if they don't drink it's 0 chance of getting it. My SO was sick so much. I was honestly fucking worried.
My SO during college, his parents called him every day and just bitched at him over his work. They even went as far as calling a counselor at his college because he got a B. They told him if he didn't go, they would make him move back to Hong Kong. Extremely protective and crazy imo. Then when he told them if they didn't stop he was going to quit and never go to school again, the he didn't care, and that they needed to just relax and give him space.. his brother called him and bitched at him for talking to his parents that way.
Then on top of everything, in a lot of these places there is public shaming. Your wife gets pissed at you over something bad, she will shame you in public. This is sorta rare, but does happen. Maybe some of you have saw videos of it. People think its funny when they see a video like that in America. BUT it is not fucking funny. Your wife gets pissed over like you buying something she didn't want you to buy, starts yelling calling you worthless in public, and instead of the people thinking she's crazy, they think the man is pathetic for not being able to handle his wife, or his family properly.
If you do anything wrong (and not only law wrong, but societies version of wrong), your family's reputation gets put down. And in Japan, Hong Kong, & China, yours and your family reputation is a huge thing. Being disgraced can cause you to lose your job, make it harder to find a job, or even be extremely criticized, or rare but possible publicly shamed. It can even make your childrens future harder if your reputation gets messed up.
The responsibility and stress that is put on men in Japan, Hong Kong, & China is extreme. It's no wonder that lots of men there commit suicide, or even hide out in their house (Hikikomori).
A lot of other stuff I could go into also. I probably left tons out. Now my SO isn't a hikikomori, but he understands the full culture, and has tons of anxiety and just overall issues now. I could answer a lot of questions if you want, and if my SO is up to it, he can also if you want to know more about certain Asian cultures.
Edit: Also women in Japan are known to treat their husbands pretty cruel. Which makes a lot of the men not even want to get married at all over there. Which as you can guess, makes them pretty lonely also in every day life. Which does play a part in hikikomori.
