Kohoku Ward was born with Totsuka Ward in April, 1939. Kohoku Ward at the time was area that put current Kohoku Ward, Midori Ward, Aoba Ward, Tsuzuki Ward   together, and population was about more than 50,000.

Afterwards, northwest area of ward was further incorporated into Tsuzuki Ward   in Midori Ward (a part of current Midori Ward, Aoba Ward and the Tsuzuki Ward  ) share ward in November, 1994 in 1969 by administrative section reorganization, and it was in current Kohoku Ward.

As for the Kohoku Ward, making began quickly city for inland of Yokohama-shi by current Toukyu Toyoko Line having been opened current JR Yokohama Line in 1926 in 1908.
