theory

Sakamoto assassinated to Satsuma.
There is its theory.

"Perpetrators might Mimawarigumi surely.
But mastermind was Satsuma."
There is also its theory.
I do not think so.
　
I think so from Japan's situation of that time.
Above all，Satsuma was the boss of the conspiracy surely of this period.
But that mastermind was Satsuma."
Sakamoto's case was special.
I do not think so.
　
・・・・・・・・・
　
"Conspiracy of me and Okubo at the time.
I absolutely can not speak.”
Later Iwakura said.
　
"This is confession of assassination of the Emperor."　
There is also its theory.
I do not think so.
　
I think reason of demise of the Emperor was sick.
I think it was natural from his pathology rather than from political situation.

They were sacrificing to create a shortage of liberties, then capturing a high-ranking aristocrat.
　
Meaning of Iwakura's remark.
For example,I think it was them.
　
At the time, probably this was a revolution too.
