Japan's Nikkei share average shed 1.4% on Monday after a disappointing US jobs report showed the US economic recovery remained sluggish, while a stronger yen weighed on exporters.
Exporters and financials came under pressure after they led the Nikkei rally in January to March, when the index gained more than 19% to log its best first-quarter performance in 24 years.
Honda Motor Co lost 1.8%, Toyota Motor Corp fell 1.5% and TDK Corp sagged 2.6%, while Japan's top investment bank Nomura Holdings dropped 2%.
The Nikkei was down 138.15 points at 9,550.30, holding above its 50% retracement of its fall from February to November last year, near 9,511.
The benchmark was on track for its fifth straight session of losses, which would mark its longest losing streak since November.
"We are already in the 9,500s now. We will see if that 9,500 provides support. If not, our technical analyst is looking for the 9,300 handle (for support)," said Naomi Fink, Japan equity strategist at Jefferies.
"It's an interim correction. We went, perhaps, a little too far, too fast."
US payrolls grew by 120,000 in March, worse than the forecast gain of 203,000 jobs. The unemployment rate dipped to 8.2% from February's 8.3%.
Trading was expected to be light with Australia, Hong Kong and the UK markets closed for Easter Monday and ahead of the Bank of Japan's two-day policy meeting ending on Tuesday.
The BOJ is expected to refrain from easing monetary policy this week, holding fire until a more thorough assessment of the economy two weeks later which may show further action is needed to nudge inflation up towards its 1% target. The central bank will hold another meeting on April 27.
The broader Topix dropped 1.3% to 815.35.
