The plunge in the yen¡¯s value against the U.S. dollar continues with no end in sight, harming Japan¡¯s economy by pushing up import costs.

A currency¡¯s value is affected by numerous factors, making predicting fluctuations a difficult matter, but some economists say there are potential ways of alleviating the yen¡¯s recent weakness.

Earlier this month, the yen tumbled below the key ?140 line, coming close to reaching the ?145 level, to hit a fresh 24-year low last week. With the yen having plummeted more than 20% this year, markets are watching whether the currency will breach the ?147 line seen in August 1998.
