The Japanese currency continued its gain by the end of today's trading session versus its major counterpart the US dollar, where it reached to the highest level since the World War II, after the market's expectations noted that the Bank of Japan will delay its intervention into the markets to curb the yen's appreciation, as the nation struggles to avert disaster at a nuclear-power plant after the strongest earthquake that damage the economy.

On the other hand, the yen increased by 4.5% against the dollar during yesterday's New York trading session.
