Growth in Japan's economy slowed to a crawl in the second quarter and analysts see more weakness ahead, adding to policymakers' headaches as they grapple with deflation and a rise in the yen that threatens an export-reliant recovery.

The government is considering new stimulus measures including boosting graduate employment and the corporate sector, Kyodo News Agency said late on Monday, after data that testified to slowing growth in Japan's main export destinations such as the United States and China and a stimulus-driven domestic recovery that has petered out.

Against a backdrop of concerted efforts to talk down the yen after it surged to a 15-year high against the dollar last week, quarterly gross domestic product grew just 0.1 percent for annualized expansion of 0.4 percent.

That was well below the median market forecast of 2.3 percent and the United States' 2.4 percent annualized growth in the same quarter.

It followed revised 4.4 percent annualized growth in the first quarter, when both exports and a stimulus-driven recovery in consumption contributed to overall growth.

In the April-June quarter the stimulus effects have worn off, leaving exports as the sole engine of growth and with its contribution to growth halved to 0.3 percent, the economy just eked out a third straight quarter of expansion.

Prime Minister Naoto Kan and Bank of Japan Governor Masaaki Shirakawa are expected to meet later this week o discuss possible policy responses.

I think the Bank of Japan and the government need to take decisive action against currency moves, said Takeshi Minami, chief economist at Norinchukin Research Institute in Tokyo.

Solo currency intervention is possible if the yen approaches 80 to the dollar. If that is accompanied by monetary easing by the Bank of Japan, it may have a certain effect.

Citing government sources, Kyodo said the growth-boosting government measures are expected to include stimulating personal consumption of eco-friendly products, helping new graduates find jobs and revitalizing small and midsize companies, Kyodo quoted the sources as saying.

CHINESE LEAP-FROG

The latest output figures put China ahead of Japan as the world's second-largest economy for the quarter on a nominal dollar basis, at $1.2883 trillion against $1.3369 trillion, said Keisuke Tsumura, a parliamentary secretary at the Cabinet Office.

(But) since we have different calculations for seasonal adjustments, it would be correct and fair to compare the figures for the whole year, Tsumura said.

China's top currency regulator said last month that his country's economy had already overtaken Japan's.

Japanese government bond futures jumped after the weak data, with September 10-year futures rising 0.28 point to 142.67, their highest since June 2003, while benchmark 10-year yields slipped to a seven-year low of 0.950 percent. The Nikkei stock index fell nearly 1 percent.

The economy may enter a lull late this year or early next year, or even stagnate, said Yoshiki Shinke, senior economist, Dai-Ichi Life Research Institute.

Much depends on the performance of overseas economies.

YEN PINCH

Analysts added that the rise in the yen, which climbed to 84.72 per dollar, may begin to pinch export growth in the latter half of the fiscal year to next March.

Prime Minister Kan has expressed concern about the yen's strength. We need to look at this closely, and that includes the currency problem, he told reporters when asked whether the GDP data showed the economy needed new stimulus measures.

I have asked cabinet ministers involved to report to me about the economic situation.

Late last year, the last time the yen/dollar strengthened beyond the 85 yen mark, the BOJ called an emergency meeting and announced a three-month funding scheme, a day before Shirakawa met with then-Prime Minister Yukio Hatoyama.

The yen has risen steadily against the dollar since early May, gaining more than 10 percent and closing in on its 1995 record high of 79.75 per dollar, prompting markets to speculate that Tokyo might take action.

But currency intervention is seen as difficult, whether jointly or alone, although market players say the risk of solo action increases the closer the yen gets to 80. Investors see a monetary policy response from the BOJ as more likely.

Signs of a faltering economy put more pressure on Kan ahead of his party's leadership vote next month in which he may face a challenge from powerbroker Ichiro Ozawa or a proxy, either of whom would be less keen to forge ahead with fiscal reform.

Japan's recovery has been spotty since emerging from its worst recession since World War Two in mid-2009.
