Japan's largest bank (in terms of assets), Mitsubishi UFJ Financial Group ( MTU), hit an eight-year low this week (Nov. 27). Though it was once valued at more than $200 billion, it is now valued at just $57 billion. Meanwhile, this bank generated an eye-popping $49 billion in free cash flow in fiscal (March) 2011, according to Thomson Reuters. Mitsubishi UFJ Financial has one of the premier providers of financing for inter-country trading transactions, providing shippers, manufacturers and other financial-services firms with logistical capital. In the first six months of the current fiscal year, the bank posted $9 billion in net income, or about $18 billion when annualized. This means it trades for a little more than three times annualized income. Investors interested in the Japanese banking sector should also check out Mizuho Financial ( MFG), Sumitomo Mitsui Financial Group ( SMFG) and Nomura Holdings ( NMR). These bank stocks also hit fresh lows this week, erroneously tied to the widening crisis in Europe.
