TOKYO, Jan 24 (Reuters) - Japan's Nikkei rose on Monday on bargain hunting after a sell-off last week, as investors piled into resource shares and exporters, with the mood brightened by hopes for robust October-December period earnings due this week.
The benchmark booked its biggest daily fall in 2 months in heavy volume on Friday, as energy-related stocks fell amid fears of more monetary tightening by China triggering profit-taking.
"Investors have so far reacted positively to reports of hikes in operating profit and they expect strong earnings on a pick-up in the global economy and a dollar/yen rate that kept above firms' conservative estimates," said said Masayuki Otani, chief market analyst at Securities Japan, Inc.
Big ticket exporters including Canon Inc <7751.T> and Kyocera Corp <6971.T> as well as Japan's biggest personal computer firm NEC Corp <6701.T> are due to report on Thursday.
Fuji Heavy Industries Ltd <7270.T> gained 1 percent to 688 yen after the Nikkei business daily said the Subaru-brand vehicle maker will likely post a group operating profit tripling the previous year's tally and beating earlier estimates. [
]By mid-afternoon the benchmark Nikkei <
> was up 0.4 percent, or 44.48 points, at 10,319.14, while the broader Topix index < > also rose 0.4 percent to 914.20.HONDA LEADS ADVANCE
Honda Motor Co <7267.T> led the advance on the Nikkei, adding 3.7 percent to 3,400 yen in heavy trade after the Argentine government said on Friday Japan's second-largest car maker will start producing its City model at a new plant in Argentina in March. [
]Nomura Securities also hiked Japan's second-largest automaker's rating to "buy" from "neutral" on stronger-than-expected U.S. sales.
But gains on the Nikkei were limited as construction machinery maker Komatsu Ltd <6301.T> fell 2.1 percent to 2,365 yen, while Hitachi Construction Machinery Co <6305.T> was also 1.6 percent lower at 1,937 yen, as markets cautiously awaited further tightening steps in China.
The two companies assemble and sell their products in China after importing major parts from Japan.
"Both in October and December China hiked interest rates within 10 days of raising reserve requirements for banks, so markets continue to be a bit jittery as China didn't embark on more tightening steps last week after again raising RRRs in January," said Hideyuki Ishiguro, a supervisor in the investment strategy section of Okasan Securities.
GETTING TECHNICAL
On technical charts, the Nikkei was still hovering below its 25-day moving average, a gauge often used by Japanese traders, which now stands at 10,397, showing that any improvement in sentiment is still fragile.
"On top of domestic earnings, investors may not want to take large positions before big U.S. events such as the FOMC meeting," said Kenji Shiomura, a market analyst at Daiwa Securities.
The Federal Reserve's Federal Open Market Committee will hold a two-day meeting on Tuesday and Wednesday where it is expected to paint a cautious view of the world's biggest economy.
Bargain hunters chased resource stocks after they tumbled on Friday, with Japan's biggest gas and oil developer Inpex Corp <1605.T> climbing 2.9 percent to 512,000 yen and the country's biggest commodities trader, Mitsubishi Corp <8058.T>, gaining 1.9 percent to 2,316 yen.
