There appears to be a misunderstanding in the question. The phrase "land of the Russian son" is not a known or established nickname for any country. It's possible there's a typo or misunderstanding of a different nickname.
The question should likely be either:
- "Which country is called the Land of the Rising Sun?" This is a common nickname for Japan.
- Or perhaps the user is looking for a country with strong cultural or historical ties to Russia, in which case, more information would be required to answer appropriately.
Given the single available reference relating to "Land of the Rising Sun," it's likely the intended question is the first one.
Therefore, assuming the typo and correcting the question to "Which country is called the Land of the Rising Sun?":
Japan is called the Land of the Rising Sun.
