On (1): The Soviet Union was regarded by the IJA from the 1920s up to 1939 as the most likely nation to take on in a war.
On (2): To go south would mean the IJN would get all the resources and the glory, which the IJA wouldn't tolerate until the humiliation of Khalkhin Gol meant it lost all credibility anyway. The eccentric Foreign Minister Yosuke Matsuoka was the one guy who in 1941 wanted to revive the Go North strategy, and was sacked for it.
