The old order of Japan ended and there was political and social uncertainty during the Tokugawa Era
Step-by-step explanation:
Tokugawa Era was a revolutionary period in Japanese history despite being mostly peaceful. IT was when Japan finally ended its isolation from the world and started trading and interacting with the outer world again.
The new world was a completely changed one however and the Colonizers had taken an advantage of Japan because of this.
The old bureaucracy of Japan ended and the new class struggles made the country unsure of its direction into the future with the end of the Samurai class.
