denial

Katsu founded the modern navy school and private school in Kobe (Near Kyoto) as Tokugawa’s facilities.
Sakamoto was facilitator of student of that school.
He was attract many Tosa Ronin to the school as student.
(Of course that permission had been given from Katsu.)

"Create jobs”
Maybe Sakamoto had a idea like that always.

A few years later，shortly before of his assassination.

"Era will changing for sure.
Therefore many Ronin (Revolutionary) becomes useless.　
Go to Ezo (now Hokkaido) with them，and do development of Ezo."
(As maybe agricultural soldiers because Ezo defense was an important issue.)
Sakamoto made ​​a plan like that.

"We were aiming society that is not a society like this."
After the era have changed，such people really appeared from them.
They was trying to assassinate officials of the new government of Japan.
　
・・・・・・・・・　
　
Samurai who founded the new government did aiming to denial of class of the Samurai at first.　
They abolished about 300 lords across the country，and did changed to the modern system of counties and prefectures.
This change Satsuma and Choshu had done to take the initiative.
Of course，also their internal was not calm.
(Later，large-scale rebellion occurs to Satsuma.)
　
As a result，there were a great many samurai downfall.
Their Income as feudalistic landowner that had been cut off .

They might was not want such a change.　
　
"Japan will perish if we do not do it.”
I think such a sense of crisis was support them.

Depending on one's point of view，some samurai monopolized the wealth at the expense of the many samurai.
Can considered so.

Okubo Toshimichi of Satsuma who became the most powerful man in the new government.
Immediately after put down the rebellion in Satsuma (Saigo was leader)，Okubo was killed by discontent samurai.

At that time, he had no escort.
(I think this was not good because he killed by it.)
Also there was almost no assets to him.
