In 1945, Japan announced its unconditional surrender after defeat, and the Second World War finally ended, when Japanese prisoners of war were basically sent back to China, they thought that the country and their families would welcome them very much, who knew that what greeted them was a nightmare, many defeated soldiers went home to see their wives' various performances, regretted that they did not die on the battlefield, and many soldiers finally chose to kill themselves to end their lives.
Because during World War II, militarism prevailed in Japan, so Japanese women were brainwashed by the emperor, in their hearts their husbands should be loyal to the emperor, if they died on the battlefield is a huge honor of the family, but also will get a large pension, so in their hearts do not want their husbands to come back alive, especially after the defeat and surrender of the Japanese army in their eyes are cowards and traitors.
After the end of World War II, American soldiers stationed in Japan, compared with their cowardly husbands, Japanese women prefer American soldiers, so at that time many Japanese soldiers returned to China to find that their wives had betrayed themselves, but also had children with the Americans, in the hearts of these women, the defeated husbands not only had no financial resources, but also cowardly and short, inferior to American soldiers, so they were very disgusted with their husbands.
Many defeated Japanese soldiers returned home, they were sneered at by their wives, they felt that their lives were extremely desperate, many Japanese soldiers were physically injured or disabled after the war, they could not work to earn money to support themselves, and their wives were not willing to take care of themselves, so most of them suffered from depression after returning home, choosing to end this evil life.
