The Hōjō regency oversees several significant administrative achievements.

The Council of State is established in 1225, providing opportunities for other military lords to exercise judicial and legislative authority at Kamakura.

The Hōjō regent presides over the council, which is a successful form of collective leadership.

The adoption of Japan's first military code of law—the Joei Code—in 1232 reflects the profound transition from court to militarized society.

Legal practices in Kyoto are still based on five hundred-year-old Confucian principles, whereas the Joei Code is a highly legalistic document that stresses the duties of stewards and constables, provides means for settling land disputes, and establishes rules governing inheritances.

It is clear and concise, stipulates punishments for violators of its conditions, and will remain in effect for the next six hundred and thirty-five years.
