How did an ultranationalist attitude in Japan result in greatly increased powers for the army in 1930?

The rise of nationalism in Imperial Japan meant that more and more Japanese came to see their country as a great potential power, and what a great power needs more than anything else is a large, powerful army.
During the heyday of Japanese ultra-nationalism in the 1930s, vast sums of money were devoted to making the Imperial Army one of the world's strongest. And as the army grew, so too did the political power of its leadership—especially after the ultranationalist coup of 1936, when the state became completely devoted to serving the needs of the Emperor and his Imperial Army.
It was the increasingly powerful and influential Japanese generals who devised the country's imperialist strategy in the 1930s. They saw territorial expansion into Manchuria and Korea as essential to maintaining and strengthening Japan's strategic position in East Asia. Underpinning Japanese imperialist ideology was the fanatical belief that the Japanese were racially superior to the so-called lesser races and therefore had the right to conquer and exploit them.
Economic imperatives were also a factor in Japanese territorial expansion. The country was woefully short of raw materials, many of which were readily available in China, Korea, and other parts of East Asia. Taking over these territories allowed the Japanese to plunder the available resources, many of which were needed for the war effort.
