Sega Sammy Holdings announced in April 2017 that it would relocate its head office functions and domestic subsidiaries located in the Tokyo metropolitan area to Shinagawa-ku by January 2018. This was to consolidate scattered head office functions including Sega Sammy Holdings, Sammy Corporation, Sega Holdings, Sega Games, Atlus, Sammy Network, and Dartslive.
