Asian markets mostly slipped in holiday-hit trade Monday as investors were unimpressed by a slight improvement in key economic indicators out of China and Tokyo.
The yen climbed against the dollar and euro ahead of a Bank of Japan (BoJ) policy meeting this week, while there are lingering concerns about political uncertainty in Italy as well as debt-ravaged Cyprus.
Tokyo slipped 2.12 percent, or 262.89 points, to 12,135.02 on the back of the stronger yen. Taipei fell 0.24 percent, or 19.37 points, to 7,899.24 and Seoul lost 0.44 percent, or 8.90 points, to 1,995.99.
In the afternoon Shanghai was flat.
Sydney, Hong Kong and Wellington were closed for the Easter break.
The BoJ's closely watched Tankan survey of large Japanese manufacturers for the past three months showed a slight improvement in optimism for the world's number three economy, the first uptick in three quarters.
The survey showed sentiment at minus 8 between January and March, up from minus 12 three months earlier. The figures represent the percentage of firms saying business conditions are good minus those saying they are bad.
However, the figures were unable to prevent a sell-off in shares and a jump in the yen.
Hideki Matsumura, senior economist at Japan Research Institute, told Dow Jones Newswires: "Sentiment is getting better broadly, but the improvement isn't as strong as expected."
And Tachibana Securities market analyst Kenichi Hirano said the negative reaction "may have resulted from the perception that with the Nikkei having performed so well (gaining 19 percent so far in 2012), general business sentiment should have been at least a little better".
The dollar slipped to 93.85 yen early in Asia, against 94.20 yen in New York trade on Friday, when trade was limited by the Easter holiday.
The euro bought $1.2789 and 120.05 yen compared with $1.2818 and 120.78 yen.
Australian bank Westpac said in a note to clients that investor focus was on Thursday's BoJ announcement, the first under the stewardship of Haruhiko Kuroda. He has promised aggressive measures to kick-start the economy and end decades of deflation.
Westpac added: "Some disappointment around this meeting is likely and we have a downward bias for the dollar-yen in the week ahead."
In China data showed manufacturing activity expanded at its fastest pace in almost a year last month, indicating the world's number two economy was showing signs of improvement.
The official purchasing managers' index (PMI) hit 50.9 in March, the highest since April 2012 and up from 50.1 in February. However, it was below the 51.0 that had been forecast.
A reading above 50 indicates expansion while anything below points to contraction.
Separately, British bank HSBC -- whose survey focuses more on smaller enterprises -- said its final PMI for March stood at 51.6 in March, up from 50.4 in February. That figure was also slightly off the 51.7 in HSBC's preliminary PMI last week.
Oil prices fell, with New York's main contract, West Texas Intermediate light sweet crude for delivery in May, down 42 cents to $96.81 a barrel in the afternoon. Brent North Sea crude for May was down 44 cents to $109.58.
Gold was at $1,599.00 an ounce at 0600 GMT compared with $1,598.45 late on Friday.
