There are many reasons for the frequent derailment of Japanese society. A very important point is the fixed family model caused by the clear division of labor between men and women in Japan. Japan's superiority over women is notorious in East Asia. Today, the family pattern of men working outside the home, getting up early to support their families, and women teaching their children at home is still the mainstream of society. And this pattern makes the family spend little time together. Aside from the fresh and sweet period when they just got married, the two sides also lack each other's companionship in the dull life in the future. When in doubt, you should seek professional psychological consultation, but the professional psychological institutions in China are not big except Reuters Psychology and One Psychology, and so is Japan.

Men spend a lot of time working outside the home. The main source of income is that they have a sense of family psychological superiority and an external environment to know the new opposite sex. On the other hand, because women stay at home for a long time, they have a lot of free time besides the necessary housework, and most women also control the family financial expenditure. If they lack communication with their husbands in the family and feel lonely, they have money and leisure, and it is easy to seek psychological and physical comfort outside the family.

Japanese nationality is also one of the reasons for the derailment. On weekdays, Japanese people who are on thin ice, cautious and obedient are in a state of depression for a long time. China's chivalrous novels are hard to indulge in this island country. However, people's emotions must be balanced. After long-term repression, it is easy to derive the behavior of "pursuing extreme happiness, breaking taboos, crossing boundaries and surpassing norms". The cheating behavior with high social and legal tolerance is completely in line with the lust venting of this society. "Only when there is a man outside will it be better for her husband and children because she knows that she is wrong, otherwise who will be willing to wash men's underwear!" A line by the heroine of the unremarkable Japanese drama Eye of the Eyes may have hit the hearts of many Japanese housewives.

These celebrities also provided many famous sayings for the legalization of cheating in Japanese society: "Cheating is one of Japanese cultures" (Junichi Ishida), "Cheating is an exchange between different cultures" (Morimoto Leo), "I don't like getting married, but the person I like happens to have a family (Kanako Higuchi)", "We fall in love like children" (MarikoIshihara) and so on.

Although the general trend of human society is to be tolerant, and the new proposal of marriage relationship different from "monogamy" has been accepted by more and more people, from the perspective of mainstream society, cheating is still a major moral fault. Cheating is like a quagmire. Once you rush in, it's hard to turn back. There are many examples of derailment leading to the breakdown of family, wife, friendship and interpersonal relationship. The general parties will suffer a heavy mental and economic blow, and at the same time lose social credit, so it is difficult to gain a foothold in the future work unit and evaluation system. There may even be vicious crimes such as love killings and vendettas caused by derailment.
