Former Kamiseya Communications Facility

The Former Kamiseya Communications Facility is located in northwest Yokohama City (in Asahi and Seya Wards) on a flat, 242-hectare property. Used by the United States military for many years, the land was returned to Japan in June 2015. It is a promising area with potential to revitalize outlying areas of the city, and various efforts to this end are already underway, including agricultural promotion projects and new urban development via urban land use.
