monitored

Sakamoto founded the company in Nagasaki with the aid of the Satsuma.
(It is said that Japan's first modern company.)
Many comrade of Kobe era had joined to this company.
Their salary comes from the Satsuma.
　
”I can not eat at this low pay.”
However，some person was complaining so.

I look at the amount of their salary，did not think poorly paid.
Maybe，rise in prices may have been extreme in all around japan.
I think quality of the gold coins in circulation had fallen already.

But more than anything，important for them was the protection of the Satsuma.
They were mainly Tosa ronin.
At that time，They had been considered political criminal suspect by Tosa of homeland.

Since the battle at Kyoto，Tosa Ronin and Choshu Samurai was became existence who can kill at any time by Tokugawa.
Nagasaki was Tokugawa territory.
　
Conversely Satsuma was on Tokugawa side until the last stage. (on the surface)
Because they were under the protection of the Satsuma，Tokugawa officials could not interference to them.
　
Of course，they would have been under the surveillance of the Tokugawa.
Tokugawa era was also the era of the spy.
It was not so easy.

For example，escort of Oura Catholic Church.
They were monitored the hidden Christians of Japanese along with the escort of Westerners.
The latter would have been more important.

Persons like Sakamoto.
I think They also had been monitored as dangerous elements.

”What has been orchestrated behind the scenes.”
Tokugawa officials would have grabbed quite accurately.
　
Incidentally，later the man who complain was became the Minister of Foreign Affairs.
He was not a man of Tosa.
