When exactly did Kawashima Yoshiko die?
After the Japanese surrender, Chuan Dao Yoshiko was caught by the Kuomintang and sentenced to death for treason. At that time, the civil war was fierce, and someone took advantage of the chaos to engage in a conspiracy with a high price, and replaced her with another woman during the execution. At that time, the woman was shot in the head with a gun, and no one could see who the deceased was.
Then, someone sent Chuan Dao Yoshiko to a village called Xinchengzi in Changchun City, Jilin Province, and rented a farmer's house to live in. One of the people who sent her to Changchun was her lover, and she kept an ambiguous relationship with her until 1978 died. It was this man who told the secret when he died.
When she lived in seclusion, she went to the National Assembly Temple in Tiantai County, Zhejiang Province for three months every winter, and then returned to the Northeast after the winter.
After her death, someone sent her urn to the imperial palace for storage. Now her ashes are still there. Of course, the person who sent them is no longer alive, but it is enough to prove that there must be many people who know her true identity after liberation, but they have done a good job of keeping secrets. It's hard to imagine that the government's big cleaning campaign didn't wash her out.
