Pause on the stone bank outside Kikyo-mon Gate and look up at the dazzling white watchtower of Tatsumi Yagura reflected in the deep waters of the moat. Rising two stories above massive granite revetments, this three-tiered whitewashed guard tower is one of only three original watchtowers that survived from Edo Castle. Its elegant flared hip-and-gable roofs and dark copper-plated eaves present a picture-perfect vision of feudal military architecture standing proudly against the glass skyscrapers of Marunouchi. The contrast between ancient whitewashed plaster, curving copper rooflines, and modern reflective glass office towers is breathtaking to behold from the moat bank.
The name Tatsumi denotes the south-east direction according to the ancient Chinese twelve-animal zodiac. Because the southeast was considered an auspicious direction in geomancy, this watchtower was meticulously positioned to guard the corner approach while channeling positive feng shui energy into the castle's core administrative chambers. Sentries stationed inside the upper windows had an unobstructed panoramic view across the coastal flats toward Edo Bay, tracking merchant junks and fishing vessels.
The adjoining gate is known as Kikyo-mon, or Bellflower Gate, because its ceramic roof tiles are stamped with the five-petaled bellflower crest of Ota Dokan, the legendary fifteenth-century warrior poet who built the very first fortified castle on this site in fourteen fifty-seven, long before the Tokugawa shoguns transformed it into the world's largest fortress. Dokan's poetic genius, architectural vision, and military daring laid the foundation for modern Tokyo over five centuries ago.
Today, Kikyo-mon serves as the entrance gate for staff and invited guests attending private functions at the Imperial Household Agency, and on special occasions, royal vehicles glide through these historic wooden arches under police escort.
