As far as I know it's Russia.
Russia is in the Northern Hemisphere. Russia lies in two continents, Europe and Asia, and is the largest country on Earth.
The contry that has two continents is Russia. The two continents in Russia are Europe and Asia. By the way you could have googled "The seven continents of the world" in images it would have been much quicker.
Russia, Turkey, Kazakhstan, Georgia, and Azerbaijan are the only countries to span the two continents.
Russia is located on two continents: Europe and Asia. The majority of Russia's landmass lies in Asia, while a small portion is in Eastern Europe.
Japan is the island country that lies off China, Korea, and Russia.
Russia is located in both Europe and Asia. The majority of its land area lies in Asia, while a smaller portion lies in Eastern Europe.
Mongolia is the country that lies between China and Russia. It is located in East Asia and is bordered by China to the south and Russia to the north.
Russia borders 10 countries so no one country can be said to lie closest to Russia.
The largest country in the World (as of 2017) is Russia. I'll leave it to you to check whether the other properties you specified apply to this country.
