Despite expectations of a massive flight of investment capital out of Japan, investors there are continuing to pour money into domestic assets:

They sold 78 billion yen ($785 million) of foreign currency-denominated toshins, or investment trusts, last week, although the pace of selling slowed from the previous week of 254 billion yen, according to Nomura.
Nomura said in a report that Japanese investors were taking advantage of the weak yen to lock in profits.
