Tokugawa Shogunate

The Tokugawa Shogunate, also known as Japan. Is a island country in Asia. It's made up of multiple islands, the main and biggest one being Honshū, which holds Japans/Tokugawa's capital: Edo.

Description
The Tokugawa Shogunate is a very isolated nation that does not often involve with foreign affairs. Recently, due to widespread isolationist ideals, it became very strong and populated due to less chance to get a disease from the outside or go to war with another nation. Japan had no real military and heavily relied on Samurais to protect the civilians, not to mention they had extremely outdated weapons compared to Western Powers. They did have a little supply of guns from foreign trading though. Will you make Japan a very militarized power in Asia or will you embrace isolationism?
