Japan's benchmark Nikkei 225 index finished a tick above the flatline, throwing away earlier gains as the dollar-yen pulled back, but held on to a fresh 15-year high. The key stock index has finished at multi-year highs five times over the past six sessions.
Among the raft of data released before market open, the closely-watched consumer inflation eased for a sixth straight month in January, pushing the Bank of Japan further from its 2 percent target. Stripping out the effects of a sale tax hike, the nationwide consumer price index (CPI) rose a less-than-expected 0.2 percent, down from 0.5 percent in December.
Exporter stocks finished mixed; Automakers such as Honda, Suzuki Motor and Toyota Motor made losses between 0.5 to 1.2 percent, while Sony and Panasonic held on to gains of over 2 percent each.
Yamaha Motor advanced 2 percent on news that it aims to start making and selling two-seater cars in Europe.
