* Moody's has placed the Aaa insurance financial strength ratings of four Japanese property and casualty insurance companies under review for possible downgrade. The agency said that its review of the four -- Tokio Marine & Fire Insurance Co, Yasuda Fire & Marine, Mitsui Marine & Fire, and Sumitomo Marine & Fire -- was prompted by anticipated reductions of insurance premium rates following the end of the government's restricted pricing system on July 1.
