Ishikawajima-Harima Heavy Industries (IHI Corporation) is now considered to be part of the Mizuho Group, and many companies in the Sumitomo Mitsui Financial Group are now more closely tied to the Sumitomo Group than the Mitsui Group. Recently there have been signs that Mitsubishi UFJ Financial Group and the Mitsubishi Group could be taking over other parts of the Sumitomo Mitsui Financial Group. Mitsukoshi merged into Isetan, a major department store with close ties to the Bank of Tokyo-Mitsubishi UFJ, to form Isetan Mitsukoshi Holdings in April 2008.
