As one of the few remaining three-story keeps from the original Edo Castle, this striking white watchtower showcases the pinnacle of traditional fortress design. Its strategic location at the corner of the moat allowed samurai to monitor the castle's surroundings, serving as both a defensive lookout and a secure armory. Today, its brilliant white walls reflecting off the water provide a stunning contrast to the nearby business district, making it one of the most iconic photo spots in the Imperial Palace grounds.

As the former main gate of Edo Castle, this historic landmark was once the dignified entrance where powerful samurai lords (daimyo) arrived to meet the Shogun.

Fuji that the Shogun himself once enjoyed from its windows.
