I’d always read that it was just part of the Japanese process of people quitting to be the real power behind the throne, something that still goes on today, but the book I’m reading at the moment has the much more convincing theory was that it was to establish the Tokugawas as a ruling family by his son taking over as soon as possible.
Why did Tokugawa Ieyasu quit two years after becoming shogun?
