By MALCOLM FOSTERTOKYO (AP) â¿¿ Japan got a dose of upbeat economic news Friday when the government said industrial production rose 2 percent in May from April, the fourth straight monthly increase, while the most-watched consumer price index stopped falling for the first time in seven months. For years, Japan has been dogged by deflation, or falling prices, which can drag on economic growth, and the Bank of Japan has set a goal of 2 percent inflation within the next two years. Prime Minister Shinzo Abe, meanwhile, has embarked on an ambitious economic revival program since taking office six months ago through massive monetary easing, public works projects and structural reforms â¿¿ dubbed the "three arrows" of "Abenomics." Data released by the government showed that the nationwide consumer price index minus fresh foods, which can be volatile, was unchanged from a year earlier after being in negative territory for six months. The last time it was zero percent was last October. And the core CPI figure for June in Tokyo â¿¿ often used as a predictor for the nation â¿¿ rose 0.2 percent. Investors bid up the Japan's benchmark stock index by more than 50 percent between the end of last year and May amid hopes for a revival, and the economy grew a stronger-than-expected 4.1 percent in annual terms in first quarter. But share prices have fallen back over the past month amid concerns about the effectiveness of Abe's reform plans, a feeling that prices rose too high too fast, and concerns over the possible scaling back of the U.S. Federal Reserve's quantitative easing as the American economy improves. The benchmark Nikkei 225 index jumped more than 3 percent by midday Friday, but those gains seemed more linked to a diminishing of concerns about the Fed's policies and a weaker yen, which was trading at about 98.7 yen to the dollar.
