Headquarters Relocation of 4X, Asahi Shimbun Group’s Advertising and Digital Creative Company

4X, the Asahi Shimbun Group company responsible for the group’s advertising, digital, and creative operations, relocated its headquarters on December 15 from the Mylne Jimbocho Building in Chiyoda Ward to the Asahi Shimbun Tokyo Headquarters New Annex in Tsukiji.

The new office is located in a 1992-completed office tower with 17 floors above ground and 4 below, offering a Gross Floor Area of approx. 18,000 tsubo (approx. 64,000 sq. ft.). The property sits a 2-minute walk from Toei Oedo Line’s Tsukiji-shijo Station, and about 10 minutes on foot from both Tokyo Metro Hibiya Line’s Higashi-ginza and Tsukiji stations. JR Shimbashi Station is approximately a 15-minute walk.

4X was launched in October through the integration of Asahi Interactive, Asahi Digital Lab, Somewrite, and DEC Management Office. As part of the group restructuring, the company consolidates previously dispersed specialist functions into a single platform. By unifying capabilities such as media operations, video and digital content production, owned media and social media management, advertising creative, and event planning, 4X aims to provide comprehensive support from marketing strategy design through execution.
