 On the long-distance Kaidō roads Tōkaidō and Nakaharakaidō built by Edo-Bakufu, stations were built in the area of what would later become Kawasaki, which increased its importance.The Kawasaki station (Kawasaki-juku, near today's Kawasaki station) on the Tōkaidō was not officially recognized until 1623 as the last of the 53 Tōkaidō stations.The Bakufu let the bridges over the Tama collapse and there were ferry connections to nearby Edo in several places in today's Kawasaki, which laid the foundation for the development of the city.
