Look up "Mitsubishi Group" on Wikipedia for some interesting insights into how "a decentralized control structure" works. I suspect that this sort of decentralisation is common not just in Japan, but throughout most large players in the global economy. The differences will mostly arise from how much the "home market" of any of these groups (cabals) will care for, or acknowledge antitrust practices.
Other good examples are Unilever, Google, Apple, Freeport McMoran, Tata Group etc. Once you bring China into the equation it becomes more difficult to trace the global connections due to massive state ownership, but I'd be surprised if they didn’t have interests in many global conglomerates.
This isn't really conspiracy theory, this is just how a global economy is evolving amidst multiple conflicting interests and regulatory bodies.
