Cash-flush Japanese retirees shun risky investments

Of the retirement generation, just 5 percent own financial assets of more than 100 million yen ($850,000), with the bulk, or 45 percent, in the range of 10-25 million yen ($85,000-$215,000), Miyai said.

Kumano said the number of retirees with a high savings ratio thanks to retirement allowances will peak around 2010, suggesting that the boom in the investment trust business could also start to peter out then.
