Factory output a key barometer of Japan's economic health was up 2.6 percent from October and logged its ninth consecutive month of growth, the government said Monday.
"A recovery in exports, especially in Asia, supported growth in industrial output," said Hideki Matsumura, senior economist at the Japan Research Institute.
Japan's exports to Asia totaled 2.7 trillion yen ($30 billion) in November more than those to North America (920 billion yen) and Western Europe (624 billion yen) combined, the finance ministry said last week. Exports to China alone in November rose 7.8 percent, the first increase in 14 months.
Among key sectors, November output for transportation machines, which include passenger cars, jumped 5.9 percent. Output for information technology equipment, which includes popular liquid crystal display televisions, gained 2.7 percent.
Shipments in November edged up 0.9 percent month-on-month with inventories rising 0.2 percent. The government forecast industrial output will grow by 3.4 percent in December and 1.3 percent in January.
Japan has struggled to shake off its worst recession since World War II amid deflation and a strong yen, which erodes the profits of Japanese exporters.
Prime Minister Yukio Hatoyama vowed Friday his government would do its utmost to spur Japan's nascent economic recovery. He unveiled a record 92.29 trillion yen ($1 trillion) budget for the next fiscal year starting in April 2010.
