TOKYO, May 27 (Reuters) - Japan's Nikkei stock average rose 0.8 percent on Tuesday, rebounding from a two-week closing low hit the previous day, with stocks that had fallen sharply such as Toyota Motor Corp <7203.T> and banks regaining ground.
Major paper firms surged, with Hokuetsu Paper Mills Ltd <3865.T> jumping nearly 7 percent after Mitsubishi UFJ Securities raised its rating on Hokuetsu and three other rivals to "2" from "3", saying printing paper price hikes should drive up their earnings.
"Stocks rose on a rebound after investors sold them off somewhat too sharply yesterday, though the market lacks direction as overseas markets were closed," said Masaru Hamasaki, senior strategist at Toyota Asset Management.
Markets in the United States and Britain were closed on Monday for holidays.
"Uncertainty in the U.S. economy continues to concern the market, but investors seem to have started thinking U.S. housing problems won't directly impact Japan and won't spread globally. You can see that from relatively solid moves in the Japanese market last week, while U.S. markets did poorly," Hamasaki said.
The benchmark Nikkei average <
> added 112.43 points to end the morning session at 13,802.62. It slid 2.3 percent on Monday to book its lowest close in two weeks.The broader Topix index <
> gained 1 percent or 13.22 points to 1,357.40.For the past week, U.S. stocks booked their worst week in three months, dropping more than 3 percent, while Japan's Nikkei shed 1.5 percent.
Zenshiro Mizuno, senior managing director at Marusan Securities, said investors bought on the dips due to solid supply and demand conditions but further gains will probably be limited for a while.
"Worries about high oil prices, inflation and the economy continue and the rebound in the market is likely to be limited," he said.
EXPORTERS, BANKS UP
Shares of Toyota added 1.2 percent to 5,070 yen, while Canon Inc <7751.T> rose 1 percent to 5,320 yen and industrial robot maker Fanuc Ltd <6954.T> gained 1.4 percent to 10,670 yen.
Hokuetsu Paper shot up 6.9 percent to 467 yen, while Mitsubishi Paper Mills Ltd <3864.T> rose 5.6 percent to 245 yen, Oji Paper Co Ltd <3861.T> gained 2.9 percent to 501 yen and Nippon Paper Group Inc <3893.T> climbed 2.9 percent to 288,000 yen.
"Despite recent scandals involving inaccurate recycled paper ratios, we think domestic paper majors will boldly raise printing paper prices," Mitsubishi UFJ Securities analyst Hiroyuki Okaseri wrote in a note dated Monday.
Bank shares, which had been also hit recently, gained, with top lender Mitsubishi UFJ Financial Group <8306.T> climbing 1.6 percent to 992 yen. Japan's No.2 bank Mizuho Financial Group <8411.T> added 2.3 percent to 525,000 yen and Sumitomo Mitsui Financial Group <8316.T> rose 2 percent to 831,000 yen.
Toshiba Machine Co Ltd <6104.T> powered higher by 6.1 percent to 771 yen after Mitsubishi UFJ Securities lifted its rating to "1" from "2," saying a recovery is in sight for moulding machines for auto makers, in addition to continued growth of large machinery.
Trade was thin on the Tokyo exchange's first section, with 690 million shares changing hands, compared with last week's morning average of 1.1 billion.
Advancing stocks outpaced declining ones by nearly 2 to 1.
