尾張勤王青松葉事件之遺跡碑 - Nagoya

It is in front of the Kindai no Yakata.

The Aomatsuba Incident occurred in Nagoya Castle in 1868 (Keio 4). By order of the 14th feudal lord Tokugawa Yoshikatsu, 14 Samurai feudal lords were decapitated. It is said that the house of Watanabe Tsuna, who was executed, was called "Aomatsuba Watanabe".

I wanted to know about the Aomatsuba Incident, so I read a book called "Nagoya Castle Aomatsuba Incident" in the Nagoya Castle Series. The Aomatsuba Incident is generally said to be "the purge of the Samurai faction by the Emperor's faction for the unification of the clan theory", but it seems that it was actually quite different. When that happens, I wonder what Yoshikatsu Tokugawa was thinking about when he dealt with this case, but at this time Yoshikatsu had been away from Kunimoto for nearly two months and was in Kyoto, so the state of Kunimoto. I think I wasn't sure. Furthermore, the political situation was also a time of turmoil from the Taisei Hokan to the restoration of the royal government. At that time, I think that the faction that wanted to punish Watanabe Shinzaemon and others forced them to make a decision without sufficient deliberation and decapitated them (decapitation instead of seppuku) without knowing it well. If you would like to know more details, please read the Nagoya Castle series "Actual Nagoya Castle Aomatsuba Incident". Even so, a mysterious story remains in the stone monument of the Aomatsuba Incident. Actually, this stone monument is the second generation, but the first stone monument is the place where Shinzaemon Watanabe and others were decapitated (a place different from now). It is said that when he remained as an officer, he invested his own money and took advantage of the shade to build the monument without permission. Is it really possible to do that? In addition, this monument was temporarily removed because it would interfere with the construction of the Aichi Prefectural Gymnasium, but it went "missing" as it was. Is this just an official's negligence? Or was there pressure to not know the details of the Aomatsuba Incident even in this era? It's a mystery. As an aside, the Japanese allspice near this monument blooms beautiful flowers in January.
