Strong concern expressed by euro-zone financial leaders moved the Group of Seven nations to suggest the yen's weakness against the euro should be corrected to reflect expectations Japan's economic recovery will continue.

Even so, the yen may remain weak against the euro for now as Japanese interest rates are expected to remain below those in the euro zone.

The yen's fall to record lows against the euro has emerged as a major focus of attention, with euro-zone politicians voicing concern that the Japanese currency's further fall will dampen the competitiveness of European exports. The yen weakened against the euro by 13 percent in the past year.
