By ELAINE KURTENBACHTOKYO (AP) a¿¿ Japan's recovery is holding steady ahead of a looming sales tax hike, economic indicators showed Friday, though weakness in wages and spending suggest it remains vulnerable to a reversal. The consumer price index rose 1.3 percent in January and factory production also climbed. Past experience suggests Japan will see a big plunge in demand after the 3 percentage point tax hike to 8 percent on April 1, said economist Masamichi Adachi of JP Morgan in Tokyo. "It is a very difficult time to gauge the underlying strength of the economy," he said. As manufacturers and retailers raise prices to compensate for higher costs they are passing them on to consumers, who already appear to be tightening their belts to compensate. Japanese awoke Friday to front-page reports of plans for hikes in the prices paid for vending machine soft drinks and plans for further increases in gas and electricity rates. Contrary to earlier expectations, manufacturers are forecasting that factory output will fall in March, following a 4 percent increase in January to about the level it was at before a massive earthquake and tsunami hit northeastern Japan in March 2011, the Ministry of Economy, Trade and Industry reported. Japan's financial industry and banks are relatively sound, compared with the 1990s. Its companies have much less debt and there is no reason to expect a major regional crisis similar to the one that slammed the economy in 1997, plunging the economy into recession. By coincidence, that period of economic trauma followed a tax hike in Japan. The government and central bank have unleashed a flood of monetary and fiscal stimulus aimed at breaking Japan free from a long spell of deflation, or falling prices, that is thought to discourage investment and spending. But the central bank needs to ensure financial markets remain stable and Prime Minister Shinzo Abe needs to deliver on promises for reforms to help make the economy more competitive, Adachi said.
