HONG KONG: Asian shares mostly fell Monday, with Tokyo slipping as emergency work to bring under control a crippled nuclear plant in Japan continued to be held up by high levels of radioactivity.
Crews battling to avoid a wider nuclear disaster at the Fukushima No.1 plant, which was rocked by the March 11 quake and tsunami, have suffered several setbacks, with workers forced to evacuate by soaring radiation levels.
Tokyo slipped 0.60 percent, or 57.60 points, to close at 9,478.53 and Sydney shed 0.19 percent, or 9.0 points, to 4,733.6, while Hong Kong fell 0.76 percent in the afternoon.
However, late buying helped Seoul to end up 0.11 percent, or 2.35 points, at 2,056.39, while Shanghai was up 0.41 percent in the afternoon.
Investors were upbeat last week as work to contain the Fukushima crisis appeared to be going well, but reports of rising levels of radiation have hampered workers' efforts, stoking uncertainty over how quickly the situation will be resolved.
And at a press conference Monday, officials for the first time mentioned the possibility that the core pressure vessels of reactors one, two and three may all be damaged, Jiji Press news agency reported.
Shares in Tokyo Electric Power Co (TEPCO), which operates the plant, plunged 17.73 percent amid criticism over its handling of the deepening crisis.
"While last week was mostly about buying back of shares following the post-earthquake sell-off, investors will be paying a closer look at the specific fallout (on corporations) from the quake," Yutaka Miura, a technical senior analyst at Mizuho Securities, told Dow Jones Newswires.
Concerns over the Japanese crisis overshadowed another strong cue from Wall Street on Friday, where the Dow closed up 0.41 percent thanks to an upward revision of the growth figure for the US economy in the last quarter of 2010.
The Commerce Department said the world's biggest economy expanded at a rate of 3.1 percent in the three months to December 31, up from the initial forecast of 2.8 percent, adding to evidence the recovery there is gaining strength.
The data and comments by Federal Reserve Bank of Philadelphia President Charles Plosser on Friday that monetary policy would have to be normalised "in the not-too-distant future" boosted the dollar.
The Fed in 2008 slashed rates to near-zero in a bid to lessen the impact of the global financial crisis and has flooded markets with cash as part of its quantitative easing policy.
A hike in rates and less money being sunk into the market leads to more demand for the unit.
In early Asian trade the dollar rose to 81.80 yen from 81.34 late in New York Friday amid hopes interest rates could rise at some point, while the euro slipped to $1.4055 from $1.4088.
Higher interest rates usually support a currency as they make it a more attractive investment proposition.
The European currency traded at 114.97 yen from 114.75 yen, although it continued to be weighed by eurozone debt worries after Portugal last week failed to pass an austerity package, with many believing Lisbon will be forced to seek a bailout.
On oil markets, crude eased slightly but uprisings across the oil-rich Middle East and military strikes on crude exporter Libya supported prices.
New York's main contract, light sweet crude for delivery in May, dipped 38 cents to $105.02 per barrel while Brent North Sea crude for May lost 14 cents to $115.45.
