The dollar edged down from a near four-year high against the yen on Tuesday as traders booked profits on its sharp rally, but the yen's weakening trend remained intact following the Bank of Japan's aggressive monetary easing plan announced last week. The dollar was last down 0.4 percent on the day at 98.93 yen, having risen as far as 99.66 yen on Reuters data, its highest since May 2009.
The euro hit 129.93 yen on Reuters data, its highest since January 2010, before stalling just shy of 130. It last traded up 0.2 percent at 129.47 yen. Against the dollar, the euro was up 0.7 percent at $1.3090, having hit a more than three-week high of $1.3098 after stop-loss buying was triggered near $1.3050. Against a basket of major currencies, the dollar index fell 0.5 percent to 82.315.
