>>12715748Japan isn't fucking Italy you fucking moron, the Sengoku period happened because of the collapse of the previous Ashikaga shogunate and ended when the Tokugawa assumed complete control and destroyed all their rivals to power. It wasn't a bunch of different "nations" like you're suggesting, it was a protracted civil war.
Japan as a nation has always existed under the divine authority of the emperor, which is what OP is referencing and is a far more accurate estimate than the akshully brainlet bullshit you're pulling. Kill yourself.
