Japan's long-suffering economy is showing further signs of growth, according to a new survey.

The government's index of leading economic indicators posted a reading of 55.6 in August, the Cabinet Office revealed, marking the fourth month in succession it has stood above the 50.0 threshold between expansion and contraction.

The last time it stayed above this level for four months in a row was between November last year and February 2003.
