Japan slipped into its fourth technical recession in five years between July and September -- spotlighting how the government's "Abenomics" policies have struggled to drag the economy out of chronic stagnation.

Official data on Monday, 16 November, showed the world's third-largest economy shrank an annual 0.8% in July-September after a 0.7% contraction in the prior quarter, putting it firmly into recession -- two consecutive quarters of declines.

Analysts say the data highlights the need for structural reform aimed at breaking through supply-side constraints, including labour shortages in a fast-ageing society -- which suffered from chronic deflation for more than 15 years.

"Abenomics' first two arrows of monetary and fiscal stimulus were meant to buy time, but Japan failed to make progress with painful reforms needed to boost its growth potential," said Hiroshi Shiraishi, senior economist at BNP Paribas Securities.

"Without reform (the 'third arrow'), the economy's growth potential remains low, making it vulnerable to shocks and to suffering recessions more often," Shiraishi added.

Economics Minister Akira Amari, at a news conference after the data was published, noted a shortage of labour available for public works projects to stimulate the economy. This highlighted a major constraint that the policymakers face -- not enough suitable workers to build growth.

Amari nodded when asked if he saw "no need" to craft an extra budget to stimulate demand right away, despite US Treasury Secretary Jack Lew proposing earlier that Japan should provide more fiscal support to ensure it returns to growth -- led by domestic demand.

Amari urged Japanese firms to use their record cash holdings to raise wages and boost capital spending to generate a virtuous circle of growth led by the private sector, instead of simply demanding yet more stimulus when such growth remained elusive.

But, Amari was targeting a corporate sector that has shown little enthusiasm for Japan's economic prospects of late.

The Reuters Tankan sentiment index for manufacturers last week fell in November from October, posting the lowest reading since April 2013. The service sector index fell in October to its lowest since March, dragged down by wholesalers and retailers.


Even though Monday's numbers were gloomy, the government maintained its cautiously upbeat outlook, saying that despite some weaknesses, the economy continued to recover moderately on improvements in job and income conditions.

"While there are risks such as overseas developments, we expect the economy to head toward a moderate recovery thanks to the effect of the various (stimulus) steps taken so far," Amari said in an earlier statement.

Amari said a big reduction in inventories was the major culprit in the third-quarter contraction. Excluding this effect, he said, final demand contributed an annualised 1.4% point to growth.

But, capital expenditure fell 1.3%, more than a median market forecast of a 0.4% decrease, to mark a second declining quarter, and revealing the sluggish state of manufacturing investment.

Private consumption, which accounts for about 60% of gross domestic product, rose 0.5% from the previous quarter, in line with the median market forecast.

While domestic demand shaved 0.3 percentage point off Gross Domestic Product (GDP) growth, foreign demand for Japan's exports added 0.1 point, the data showed.

The weak data would have come as little surprise to Bank of Japan (BOJ) officials, who had also largely factored in the recession, and now expect growth to recover in coming quarters as consumption and factory output show signs of a pick-up, however modest.

The data will be closely scrutinised by the BOJ, but board members are widely expected to keep monetary policy steady at the central bank's rate review this week, analysts said.
