The famous Nakasendo Road tethered Edo, present-day Tokyo, to the imperial capital at Kyoto.
For more than 300 years, starting in the early 17th century, its hundreds of kilometers of flagstones funneled trade and political authority through inland Japan. I imagined noblewomen traveling in uchikatsugi, veiled limpet hats. Villagers bent under yoked baskets. Tradesmen and pilgrims. Mounted samurai. Sixty-nine post towns pegged off its route. The trailside lodgings were segregated by social class.
Walking partner Soichiro Koriyama, guests Akihiro Yamamoto and Katsuki Suzuki, and I followed the Nakasendo Road for a week. It unspooled through green river valleys wedged between sharp snow peaks. It puttered along farm tracks. It turned into barren highways. One day it tricked us. Though marked clearly on a map, it was nowhere to be seen. Bewildered, we glanced about us, panting and sweating in a steep bamboo thicket. This was because the Nakasendo’s ghost had seeped away. It coursed 60 meters under our boots in a tunnel dug through the heart of a mountain.
