TOKYO: Japan - the world's second largest advertising market - experienced unexpected growth in its national economy during the first quarter of the year, thanks to an increase in capital spending.

Revised data from the Cabinet Office shows that GDP expanded during the quarter by 1% year-on-year, better than the 0.8% originally forecast and lifting the annualised growth rate to 4%.

Business investment experienced a 0.2% increase from a preliminary 0.9% fall.

Analysts warn, however, that the country will not escape the effects of the global downturn, believing  the six year economic expansion may have peaked.
