As the largest country in the world, Russia has many different regions and cultures within its borders. One of these regions is known as Asian Russia, which includes the vast majority of the country's land mass and is predominantly made up of Siberia. However, depending on the context and purpose of referring to this region, there could be several synonyms that could work just as well. These might include Eastern Russia, Siberian Russia, or even just Northern Russia if it's being contrasted with the more populous European portion of the country. Regardless of the term used, Asian Russia remains a fascinating and often underexplored part of this massive and diverse nation.
