I think the main problem is the low status of Japanese women. After they get married, they just stay at home and educate their children not to go out to work. Once divorced from their husbands, they can't integrate with society. This is a very realistic and unavoidable problem for them. They have to raise children and accept other people's strange eyes. With children, they can't have a high income, and they can only support themselves and their children with meager wages and social subsidies every month.

In addition, because these single mothers can't find high-paying jobs with their children, most of them work as waiters in some convenience stores or some restaurants. The wages of these jobs are very low and they will be very tiring. It is even more difficult for single mothers to take care of their children and work to support them. Some twenty-seven-year-old single mothers are tortured by this life for more than ten years and want to find someone to remarry, but Japanese men rarely accept a woman with children.

After divorce, the ex-husband will hardly give alimony, because Japanese law usually awards the child to the mother, thinking that the mother is more suitable to take care of the child, while the father only needs to pay the prescribed alimony every month. Those divorced men can't do it at all. They just turn a blind eye to their children and continue to live a happy life. Their irresponsible attitude made mother disheartened but helpless. There is no reason to say that the child can't live without the ex-husband's payment.

So the life of single mothers in Japan is very poor. Their original family thought that their married daughter didn't need to come back and live at home, let alone help her with the children. Single mothers have to rely on themselves because there is no other way.
