Mito Kaidō (水戸街道) was an old road, kaidō, in
Japan starting from the center of Edobashi (today’s Nihonbashi). It was built to connect
Edo with
Mito in modern-day
Ibaraki Prefecture. Travelers from Edo called it the Mito Kaidō, but travelers from Mito called it the Edo Kaidō. Today,
National Route 6 follows the old Mito Kaido.[1]
