Nobunaga once married his second daughter, Deji, to Konka's eldest son, Xinkang, but the couple were not harmonious, especially Deji and Xinkang's biological mothers, who were also Konka's first wife and Imagawa Yoshimoto's niece, Mrs. Zhushan. When Deji returned to Antu to visit her mother, she cried and told Nobunaga how unfriendly Mrs. Tsuyama was to her, and reported by innuendo that Mrs. Tsuyama had secret contact with Takeda's family. ?

Nobunaga sent someone to investigate the matter, and the report was that Mrs Zhushan had secretly informed the Takeda family that she was going to force Konka to abdicate and let her successor Xinkang inherit the Tokugawa family. There is no doubt that if the rumor is true and the rebellion does occur, Nobunaga's strongest ally Tokugawa will fall to Takeda's side, and the eastern front will never be at peace. Nobunaga was very angry and wrote to Tokugawa Ieyasu asking him to execute Mrs Zhushan and Shinkang Tokugawa who dared to resist.

Peter said Nobunaga's letter was sent to Okazaki, and the disaster in Tokugawa Ieyasu fell from the sky, which made him stunned. He quickly wrote back and argued, "I know nothing about mountain building, but Xin Kang will definitely not take part in the rebellion. Please take back his life." Nobunaga's answer is: "If you kill his mother, how can you expect his son's loyalty?" ? As long as Mrs. Zhushan's guilt is true, both mother and son are guilty of the same crime and cannot be forgiven. Don't worry about my daughter, please do it as soon as possible. "After repeated ideological struggles, Konka was forced to kill Mrs. Zhushan with tears in her eyes, and forced Xinkang to commit suicide, so as to abide by the Covenant of the Yokota family and safeguard the happiness of the family.

Legend has it that Tokugawa Xinkang people are looking forward to it. Many people in the Tokugawa family opposed the execution of Xinkang, and even some ministers advocated breaking diplomatic relations with the Ministry of Information. Yan Ping, a servant of Xinkangfu, wanted to take responsibility and asked to dedicate his head to nobunaga. However, after judging the situation, Konka thought that these small measures could not calm Nobunaga's anger, so he decided to execute Nobunaga. On August 29th, first of all, Zhushan Temple was escorted to Ercuo City (the guardian was Okubo Tadashi) and was killed by Tokugawa's Interior Minister Okamoto Tazhong by Sakamoto Lake. Then on September 15, Xinkang, who had been kept in Ercuo City since the incident, was ordered to have his abdomen removed. This mistake was caused by Hattori's justice, but justice cannot wield a knife at his master. Finally, the Arab road, which is responsible for checking the death, just made a mistake. 2 1 year. After his death, some courtiers followed him.

But there is also a saying that Tokugawa Shinkang is arrogant and irritable, and many ministers are very disgusted with him. Nobunaga just listened to the opinions of these Tokugawa ministers and decided to give Xinkang a death. However, although these retainers were dissatisfied with Xin Kang's temperament, they didn't mean to depose him or kill him.

In addition, there is a sentence in the story of Sanhe: Shinlang saw Xinkang's extraordinary appearance and was afraid of losing his position. He deliberately fabricated letters to force Konka to get rid of his eldest son. However, this statement is gradually not accepted, because in another history book, Song Pingji, it is mentioned that "let him (Xin Kang) commit suicide, and the day is the first day of August of the seventh year." If Nobunaga is angry about this, let him decide. " This is completely contrary to the record, which changes Nobuyoshi Oda from a leader to a notified person.

In addition, the so-called power struggle within the family is that the story of Three Rivers emphasizes Sakai Tadatsugu's responsibility in the death of Xinkang, accusing Sakai Tadatsugu of not effectively defending Xinkang or blaming Xinkang. However, in the literature of New Guangming Temple handed down from generation to generation, there are letters from Konka and Yoshida Shintoi, which indicate: "This time, I got a report from the Governor of Saemon (Tadashi).

It can be seen that Tokugawa Ieyasu himself really played a leading role in the case of the death of Xinkang. As for why the struggle between Tokugawa's father and son turned into an endless situation, there are different opinions. One is that Takeda should say that this is the reason for continuing the dominant theory of Nobuyoda in the past. Although the Tokugawa family had sporadic exchanges with Takeda at that time, there was no evidence for Xinkang himself.

In addition, there is a conspiracy theory about Konka being hunted down and released. Due to Tokugawa's long-term support for Oda's war, it caused great economic pressure on Sanhe. The Sanhe school etiquette headed by Ishikawa Numei intended to establish the new Kang succession, which led to Tokugawa Ieyasu's counterattack. There is no evidence to prove this. It's just that there have been a lot of changes in the etiquette of Sanhe, such as Ishikawa Chunchong, Duke of Xiaohe, father and son, Ben Duofu, who are engaged in the service of Xinkang, and were ordered to commit suicide.
