During the Meiji period the samurai status was taken from them and being a force of above 1.9 million,

outrage was imminent.​

  a. The samurai rights were revoked;

such as, the right to bear arms, low

taxation in return for military assistance,

and high status in the class hierarchy.

   b. This started riots and rebellions, and

one famous rebellion, the satsuma

rebellion  which turned into a civil war.

   c. The war wasn't won it was more

reconciled, and this was the last violent

outburst regarding political freedoms.

This was another large push for political

reforms.​ Another big push was

Commodore Perry, who brought the idea

of western civilization to japan.
    Commodore Matthew C. Perry (Yes, Matthew Perry is his name) was a US Navy commander, who traveled to Japan in hopes to open their ports to international trade.
    Within the Meiji period Japan advanced to catch up to western civilization.
