A code of laws is established to regulate the daimyo houses.

The code encompasses private conduct, marriage, dress, and types of weapons and numbers of troops allowed; requires alternate-year residence at Edo; prohibits the construction of ocean-going ships; proscribes Christianity; and stipulates that bakufu regulations are the national law.

Although the daimyo are not taxed per se, they are regularly levied for contributions for military and logistical support and such public works projects as castles, roads, bridges, and palaces.

The various regulations and levies not only strengthened the Tokugawa but depletes the wealth of the daimyo, thus weakening their threat to the central administration.

The han, once military-centered domains, become mere local administrative units.

The daimyo does have full administrative control over their territory and complex systems of retainers, bureaucrats, and commoners.

Loyalty is exacted from religious foundations, already greatly weakened by Nobunaga and Hideyoshi, through a variety of control mechanisms.
