Obstacles are piling up in Japan, everything from political scandal to a rising yen. Foreign investors are fleeing and now Goldman Sachs Group Inc. says its forecasts for stocks were too high.

The brokerage lowered its three-month target for the Topix gauge by 5.6 percent to 1,700, implying a slight decline from its current level. Goldman also reduced its six-month and 12-month targets 2.7 percent and 2.5 percent, respectively, to 1,800 and 1,950. The index closed at 1,817.56 points last year.

Foreign investors yanked ¥8.2 trillion out of Japanese stocks in the first three months of the year, mainly from futures, due to uncertainty surrounding domestic politics, a rising yen, global trade concerns and mixed macroeconomic data, according to Goldman.
