Japan's household spending fell more sharply than expected in August, as state of emergency curbs to combat the coronavirus pandemic weighed on consumption during the summer holiday season and risked undercutting the economy's recovery.

The 3.0% year-on-year decrease in spending was worse than a median market forecast for a 1.5% drop and followed a 0.7% increase in July.
