* Nikkei trims gains as yen advances
* RSI over 70 signals overbuying, profit-taking emerges

TOKYO, Dec 7 (Reuters) - Japan's Nikkei stock average rose 1 percent on Monday, helped by the dollar's surge against the yen late last week, although it came off a five-week high as the Japanese currency regained some ground.
Japan Airlines Corp <9205.T> gained 7 percent after a government source said it is considering guaranteeing about 700 billion yen ($7.8 billion) in loans and other funds for the debt-laden airline. [
]Market players said the benchmark Nikkei <
> had risen about as far as it was going to on the dollar boost produced by better-than-expected U.S. jobs data."There's some concern about the speed of the Nikkei's rise, and this is leading to profit-taking," said Hideyuki Ishiguro, a strategist at Okasan Securities.
"Given that the government's now announced some economic policies the market's unlikely to fall much, and I'd say that over the short-term it'd be pretty hard for the market to fall much below 10,000. But strong gains are also unlikely."
U.S. employers cut 11,000 jobs in November, the smallest loss since the recession began in December 2007, against market expectations of 130,000, and the unemployment rate also dipped to 10 percent from 10.2 percent. [
]"The U.S. jobs data has sparked interest in a greater range of riskier assets, and this is sending investors back to stocks," said Hiroichi Nishi, general manager at the equity division of Nikko Cordial Securities.
The Nikkei rose 97.43 points to 10,120.02 after earlier rising as much as 1.8 percent. Last week it rose 10.4 percent on the week, its biggest weekly gain in more than a year.
The broader Topix <
> rose 0.8 percent to 896.39.Market players said that while the jobs news had given shares quite a boost, at the same time the strong figures fuelled expectations that the Federal Reserve may have to start considering raising interest rates.
GAINS MAY SLOW
"Put this together with the speed at which the Nikkei rose last week and I think it'll be tough for it to sustain gains above 10,200," said Nagayuki Yamagishi, a strategist at Mitsubishi UFJ Securities.
With the Nikkei's 14-day Relative Strength Index above 70, generally considered overbought territory, market players said it could be vulnerable to profit-taking.
The dollar lost 0.7 percent, falling to 89.84 yen. <JPY=>
Exporters pared some of the morning gains made on the weaker yen and hopes that the jobs figures point to an increasingly strong economic recovery. Investors fret about a strong yen because it eats into exporter profits when repatriated.
Sony Corp <6758.T> held onto gains of 1.6 percent to 2,550 yen, while Canon Inc <7751.T> gained 2.2 percent to 3,710 yen. But Honda Motor Co <7267.T> was flat.
Token Corp <1766.T> fell 8.1 percent to 2,510 yen after the apartment builder cut its annual forecast, citing weak demand.
The company said on Friday it now expects 1.74 billion yen in operating profit for the year ending in April 2010, down 78 percent from its earlier forecast. (Reporting by Elaine Lies)
