NEW YORK, March 31 (Reuters) - The dollar on Tuesday ended the first quarter on a high note, posting its best performance against the yen since December 2001, as a rally in stocks and weak economic data out of Japan dented the Japanese currency's safe-haven allure.
The yen fell to its lowest level in more than three weeks against the dollar after data showed Japanese unemployment hitting a three-year high and Prime Minister Taro Aso pledged to submit an extra budget to fund a new stimulus package to fight recession.
