Why are Japanese called imperial army?

The Japanese emphasize loyalty to the emperor. In foreign wars, the purpose of war is to "serve the country", and the country is the imperial clique (real power is not). Therefore, the troops loyal to the emperor are collectively called the imperial army. Taijun is a Japanese name for a senior officer. I remember a joke about the imperial army, the Japanese army, the self-defense forces and the Japanese. . Hehe, Japanese soldiers are very sexy, so they are called Huang Jun! That's what color wants to do, so it's called the Japanese army. Later defeated, you can't do that, you can only call masturbation team! Masturbation is to be Japanese, so it is called Japanese.
