Which castle was the headquarters of the Tokugawa shogunate in Edo?

Edo Castle was the headquarters of the Tokugawa shogunate in Edo.

Tokugawa Ieyasu took control of Edo Castle after the Battle of Sekigahara in 1600 and made Edo his political base. The castle expanded dramatically under successive Tokugawa shoguns, becoming one of the largest fortified complexes in the world. It included multiple baileys, moats, gates, residences, and administrative spaces.

Edo was the shogunate’s seat while the imperial court remained in Kyoto. This arrangement made the castle the center of military government, daimyo attendance, court ceremony, and national administration for more than two and a half centuries.

After the Meiji Restoration, the imperial family moved into the former castle grounds. The site is now the Tokyo Imperial Palace. The original main tower was destroyed by fire in 1657 and was never rebuilt.
