 Around the Heiken-ji Buddhist temple (better known as Kawasaki-Daishi), founded in 1128, a monzen-machi, a busy district for the supply of pilgrims, soon emerged.Between the Kamakura period and Sengoku period, smaller feudal lords ruled the area until it finally came under the control of the Later Hōjō clan.In 1611, Koizumi Jidayū had Nikaryō Yōsui built, a canal system on the right bank of the Tama for irrigating the fields, which in some cases still runs through the densely built-up city.
