The Mongols were unable to conquer Japan.

To identify a country that the Mongols were unable to conquer, we can analyze the physical geography of the area. Let's examine the options provided.

1. Russia: The Mongols successfully conquered Russia during the 13th century. Under the leadership of Genghis Khan and his successors, they established the Golden Horde and ruled over parts of present-day Russia for several centuries.

2. Egypt: The Mongols made several attempts to conquer Egypt in the 13th century, but they were ultimately unsuccessful. Egypt's geography, including the Nile River and the difficult desert terrain, made it challenging for the Mongols to penetrate and conquer the region.

3. Iran: The Mongols successfully conquered Iran, including parts of modern-day Iran, Iraq, and other surrounding territories. They established the Ilkhanate, which ruled over the region for several decades.

4. Japan: The Mongols attempted to invade Japan twice in the 13th century, in 1274 and 1281, but they were unable to conquer the country. The geography of Japan, specifically the island nature and the strong naval capabilities of the Japanese defenders, played a significant role in repelling the Mongol invasions.

Therefore, based on the provided options, Japan is the country that the Mongols were unable to conquer due to its physical geography.
