Fushimi Castle
The edicts were first read to a gathering of "daimyō" by the retired "shōgun" Tokugawa Ieyasu, at Fushimi Castle in the seventh lunar month of 1615. They had been compiled by a number of scholars in service to the shogunate including Ishin Sūden, and were aimed primarily at limiting the power of the "daimyō" and thus protecting the shogunate's control over the country.
