Abstract: Tokugawa Hidetada "Kill Chickens and Scare Monkeys" in Japan Tokugawa Ichimon suffered a change of name
Attendance was an important system in Japan's Edo period, and it is also a point of historical knowledge that modern Japanese students must learn. The system of attendance began with the birth of the Edo shogunate and was institutionalized during the reign of the third shogun, Tokugawa Iemitsu. The attendance was to demand that all the major names of the country come to the side of the lord Tokugawa shogun and fulfill their obligations to submit to the shogunate.
In principle, attendance is for all names. Even Tokugawa Ichimon is no exception. If you neglect to attend the work, you will wait to accept the punishment of change and cut off the door. If you think that Tokugawa Ichimon can skip the work, Matsudaira Tadao, Tokugawa Ichimon, is a role model!
Matsudaira Tadao was the concubine of Tokugawa Hidetada's half-brother Yuki Hideyasu, and his son was the highest of 670,000 stones among Tokugawa Ichimon daimyōs. The main room is Hidetada's third daughter, Katsuhime. However, Tadashi began to neglect Edo's attendance at work on the pretext of illness from Motoharu. The reason was that Tokugawa Ieyasu annihilated the Osaka Summer Formation of the Toyotomi family.

At that time, Matsudaira Tadashi led his army to fight bravely, not only defeating the Sanada army, which was brave and brave and broke into the Ieyasu Honjin, but also killing Yukimura. However, Tokugawa Ieyasu only rewarded the tea vessel Hatsuka Shoulder Guard as a reward, but did not order an increase. Matsudaira was rather unhappy about this.
He had originally thought that it was not surprising that his father, Hideyasu Yuki, had replaced Hidetada on the throne of the general. The Tokugawa family was also divided, but their official position was lower than that of the Gozo family, which became a source of dissatisfaction with Matsudaira Tadasunaga. Tadashi's dissatisfaction with the shogunate grew, and he finally refused to attend the military service under the pretext of illness.
Although the system of attendance at this stage had not yet been formally established, in order to swear allegiance to the shogunate, the daimyōs rushed to Edo. In contrast, refusal to leave for duty was seen as a rebellion and sent to pursue the army. At this juncture, Matsudaira Tadao's change of heart was originally a matter of inability to return to heaven, but Tokugawa Hidetada, seeing that Tokugawa Ichimon was concerned, did not punish him, but only urged Matsudaira Tadao to leave quickly.
In the seventh year of Motowa, Matsudaira Tadashi finally set off from Fukui, but unexpectedly, the team stopped in Sekigahara on the way, and after staying for a long time, Matsudaira Tadao returned to Fukui after claiming illness. Instead, he sent his sister-in-law Mitsunaga, who was born to Katsuhime, to Edo. In the eighth year of Motowa, Matsudaira Tadashi returned to Edo to attend the service, only to return on the way.
Since the arrival of the Osaka Formation, Matsudaira Tadao has been complaining for a long time, resulting in his mental state being out of normal track. It is said that he attempted to kill Masamune Katsuhime and even eliminate the Nagami Sadasumi clan. This move, of course, caused panic among the courtiers, and Tokugawa Hidetada was unable to turn a blind eye to what Matsudaira Tadashi was doing.
In February of the 9th year of Motowa, Tokugawa Hidetada asked Matsudaira to live in seclusion and cede the position of governor to his concubine Mitsunaga. If he refused, even Tokugawa Ichimon would be attacked, and Tadao had to comply with the request and go to the exiled land of Bungo Province in March.
In fact, Tokugawa Hidetada had already arranged everything, and in July of the same year Tokugawa Hidetada ceded the shogun's position to Iemitsu. But before he can do so, he must straighten out to Tokugawa's internal instability. Matsudaira Tadashi is one of the sources of this instability. For a disgruntled relative who believes that his father and himself are relatives of the general, ostensibly exiled to Fenghou is the best choice for substantive reform.
The Tokugawa shogunate showed a strong attitude toward the outside world, as long as it was sluggish in attending the work, even the Tokugawa Ichimon would never let go of the attitude, which greatly shocked the major names. Needless to say, Matsudaira Tadashi's substantive change of heart had achieved the shogunate's goal. Not only did he succeed to the shogunate smoothly, but he also urged the major names to abide by the effects of the Edo Duty Regulations
