Central Chamber
Quick Summary
The "Central Chamber" refers to the Sei-in, a part of the Dajōkan, which was the council of state in Japan's imperial government during the Nara and Heian periods. After the 1868 restoration of imperial power, the new government's council of state was also named the Dajōkan. This body was reorganized in 1871 into three chambers: the Left Chamber (legislative), the Right Chamber (directing ministries), and the Central Chamber, which absorbed the powers of the other two. The Dajōkan was eventually abolished in 1885 and replaced by a Cabinet responsible to the emperor, preceding the promulgation of Japan's first constitution. Modern Japan's government operates under a constitution established in 1947, featuring a separation of powers among legislative, executive, and judicial branches.12
