Here's how it works:
* Common noun: "Country" refers to a general concept of a nation or territory, like "The country is known for its beautiful landscapes."
* Proper noun: "Country" becomes a proper noun when referring to a specific country, like "I visited the country of France."
Therefore, the proper noun for "country" will always be the specific name of the country you are referring to, for example:
* United States
* Canada
* Japan
* Brazil
