This article in The Japan Times talks about the merger of Takashimaya Department Store (my former employer in Tokyo) with Hankyu and Hanshin Department Stores (H20). Both Takashimaya and H20 are based in Osaka.
This is following the announced mergers of Isetan and Mitsukoshi and the other merger of Daimaru and Matsuzakaya.
As a former employee of Takashimaya, it will be interesting to see if/what changes at Takashimaya. Or, if there are changes at Hankyu or Hanshin as a result.
