* Eases after 4-1/2-mth closing high; exporters, banks down
* Profit-taking weighs but uptrend to continue - strategist
* Resistance expected near 10,000, then 2010 high eyed

TOKYO, Nov 12 (Reuters) - Japan's Nikkei inched down on Friday, taking a breather after ending the previous day at its highest in 4-½ months, but analysts said more gains were in store as the outlook for the global economy brightens.
A clear break above 9,800, a peak hit in July and breached this week, has triggered successive waves of stop-loss and option-related buying. That is paving the way for a climb towards 10,000, though traders say this level will likely serve as resistance.
"Profit-taking emerged as the market has climbed rapidly since last week. But today's weakness is simply a correction and doesn't really signal a change in the overall trend," said Soichiro Monji, chief strategist at Daiwa SB Investments.
"In addition to ample liquidity, uncertainty over the outlook for the global economy is receding, as you can see in recent economic data from the United States, such as jobs numbers."
The benchmark Nikkei slipped 0.3 percent to 9,830.35. It rose 0.3 percent to 9,861.46 on Thursday to book its highest close since June 24, when the Nikkei last traded above 10,000.
Technical trends have turned stronger since the Nikkei decisively broke above 9,800 on Wednesday. After 10,000, analysts see this year's high of 11,408.17, hit in April, as its next target.
Monji said the Nikkei would likely reach that level early next year, also citing solid Japanese corporate earnings.
Global stocks had been boosted by the Federal Reserve's plan to buy $600 billion of Treasuries to lower interest rates and reinvigorate the economy.
The broader Topix fell 0.2 percent to 854.78.
The dollar rose above 82 yen this week for the first time since early October. In early Asia trade it was at 82.36 yen.
Analysts said the market is closely watching the outcome of the G20 summit in South Korea, where discussion was expected to include exchange rate policies and global economic imbalances, though few investors expect a sweeping agreement.
Shares of exporters that had led gains in recent sessions lost steam, with Advantest down 1.9 percent at 1,616 yen and TDK slipping 1.5 percent to 5,160 yen.
Bank shares that had strengthened after the Financial Times reported this week that most major Asian banks could be exempt from planned global regulations also fell.
Mitsubishi UFJ Financial Group fell 1 percent to 395 yen and Sumitomo Mitsui Financial Group declined 1.6 percent to 2,515 yen.
Mizuho Financial Group shed 2.3 percent to 127 yen, after the Nikkei business daily reported that the bank would buy a stake of about 2 percent in BlackRock Inc, the world's largest money manager, for $500 million.
