About Seya Ward
Seya Ward of Yokohama was created in 1969 when it was split off from Totsuka Ward. Famous for the cherry trees lining Kaigun Road (“Navy Road”), it is rich in greenery such as Nagayamon Park and Seya Citizens' Forest. The ward office is in Futatsubashicho, and moved in 2012 to a new building shared with the fire station.
