How did trade between the US and Japan affect the Japanese government?

The United States and Japan have reached an agreement in which Japan will eliminate or lower tariffs for certain U.S. agricultural products. For other agricultural goods, Japan will provide preferential U.S.-specific quotas. Once this agreement is implemented, over 90 percent of U.S. food and agricultural products imported into Japan will either be duty free or receive preferential tariff access.

Explanation:

In 1853, the U.S. government demanded that Japan (then a closed country) reopen trade with the West. In 1854, the U.S. government (through gunboat diplomacy) forced the Japanese government to sign a treaty, opening Japan up to trade with the U.S.
