Japan is expected to re-emphasize its resolve to achieve structural reforms aimed at revitalizing its economy when finance ministers and central bank governors from the Group of Seven major economic powers gather this week in Washington.

The meeting, scheduled for Friday and Saturday, will take place amid mounting calls for Japan to produce "tangible results." Nearly a year has passed since the reform-minded administration of Prime Minister Junichiro Koizumi rose to power last April, and any visible accomplishments have been few.

Observers say Japan may have a difficult time winning the confidence of its G7 partners for its structural reform efforts.
