Stop before the impressive, elongated wooden structure of Hyakunin-bansho, stretching more than forty-five meters along the stone path. Built in the late Edo period, this is the largest surviving guardhouse in all of Japan. Its whitewashed plaster walls, dark cedar beams, and traditional tiled roof look remarkably pristine, transporting you directly back to the tense feudal atmosphere of eighteenth-century Edo. The building once housed hundreds of flintlock firearms, heavy polearms, and samurai swords neatly racked along the interior timber walls, ready for instant deployment at the first sound of alarm bells.
The name Hyakunin-bansho means the Hundred-Man Guardhouse. Day and night, this post was garrisoned by four elite samurai companies of twenty-five men each, drawn from the Tokugawa clan's most trusted retainers: the Koga ninja gunners, the Negoro matchlock troops, the Iga ninja guards, and the Twenty-Five Horsemen. Together, these one hundred heavily armed warriors defended the inner approach to the Honmaru palace with unflinching vigilance, sworn to protect the shogun with their lives.
Whenever a daimyo lord arrived for his mandatory alternate attendance, or sankin-kotai, in Edo, his entire retinue had to dismount here. The hundred guards would rigorously inspect the lord's papers, count his samurai bodyguards, and ensure that no firearms or unauthorized weapons were smuggled into the shogun's private residence, strictly enforcing shogunate security edicts that maintained peace across Japan for over two hundred and fifty uninterrupted years.
Look closely at the stone foundation beneath the wooden pillars: the stones are dry-stacked with paper-thin precision, allowing seismic shocks to disperse harmlessly through the masonry joints, which is why this timber building has survived centuries of earthquakes without buckling or tilting.
Continue up the gentle stone ramp toward the vast lawn of the Honmaru and approach the colossal stone mound of the Tenshudai.
