In the 18th year of Tensho (1590), Toyotomi Hideyoshi, who had eliminated the Hojo family, ordered Tokugawa Ieyasu to surrender his old domain and move to Kanto. Interestingly, the biggest victim of Tokugawa Ieyasu's move to the Kanto region was not Tokugawa Ieyasu and his family, nor Toyotomi Hideyoshi (only at that time), but Oda Nobuo, the son of Oda Nobunaga. What's going on here? This ghost will talk about the family.
Oda Nobuo is the second son of Oda Nobunaga (one says the third son), and is the same brother as Oda Nobutada, who inherited the family governor. Oda Nobuo was succeeded to the Kitabatake family in Ise in his early years and changed his name to Kitabatake Nobuo. After Oda Nobunaga died in the "Honnoji Incident", Oda Nobuo returned to his family and competed with Oda Nobutaka, Toyotomi Hideyoshi, Shibata Katsuie and others for his father's inheritance, triggering the "Komaki Nagakute War".
Oda Nobuo surrendered to Toyotomi Hideyoshi after the Battle of Komaki and Nagakute, and became a daimyo with a territory of up to one million koku. Most of Mino, Owari, and Ise, where Oda Nobunaga started, were all Oda Nobuo's territory. In the fifteenth year of Tensho (1587), Oda Nobuo was made Minister of the Interior and became the second-highest nominal samurai in the Toyotomi regime, ranking even above Toyotomi Hidenaga and Tokugawa Ieyasu.
The main reason why Toyotomi Hideyoshi treated Oda Nobuo so favorably may be to win over and appease the former retainers of the Oda family. But as Toyotomi Hideyoshi completed the unification of Japan, Oda Nobuo's value gradually diminished. So Toyotomi Hideyoshi, after the fall of the Hojo family, decided to knock his two biggest potential opponents (Tokugawa Ieyasu and Oda Nobuo) at the same time, and the method of beating was to transfer the territory.
When Tokugawa Ieyasu moved to Kanto, Toyotomi Hideyoshi ordered Oda Nobuo to take over Tokugawa Ieyasu's old collar (Junyuan Sankoshin), and Oda Nobuo's old collar Mino, Owari, and Ise were handed over to Toyotomi Hideyoshi for redistribution, that is, Oda Nobuo moved the seal of Junyuan Sankonobu. In order to get Oda Nobuo to agree, Oda Nobuo's territory was 1,557,000 stones, an increase of one-third.
However, unlike Tokugawa Ieyasu, who honestly moved the Kanto region, Oda Nobuo refused to transfer the seal on the grounds that Nomao was the ancestral domain of the Oda family, which annoyed Toyotomi Hideyoshi. So Toyotomi Hideyoshi, in a fit of rage, confiscated all of Oda Nobuo's territory and handed Oda Nobuo over to Akita Minoru of Dewa Province to be imprisoned. Oda Nobuo, the former Nobuo of the Toyotomi regime, was in a state of collapse.
