Nikkei up 2.1%
Japan's benchmark Nikkei 225 touched a two-week high, buoyed by dollar-yen which inched up above the 118 handle - its highest in a week. Exporter stocks including Nikon and Panasonic rallied more than 3 percent each, while automakers Toyota Motor, Suzuki Motor and Nissan also made gains between 2.6 and 1.8 percent each.
Sharp bucked the rising trend to retreat 1.3 percent on news that it could slide back into the red this financial year due to fierce price competition in television and other key products.
Trading house Itochu was among the top losers for the day, retreating 2.5 percent after it announced that it is teaming up with Thailand's CP Group to invest in China's Citic Group.
Meanwhile, the Bank of Japan commences its two-day monetary policy on Tuesday and it is unlikely to roll out further easing, analysts say. "Cheaper oil is a bliss for Japan. They are already buying enough JGBs and the yen is weak enough so there is no reason for additional easing," Takuji Okubo, principal and chief economist at Japan Macro Advisors, told CNBC Asia's "Squawk Box."

Australia's key S&P ASX 200 index closed little changed on Tuesday, helped by positive data from China which helped the bourse to pare an earlier 0.5 percent decline. Meanwhile, the Australian dollar ticked down 0.5 percent to buy $0.8175 to the dollar.
Rio Tinto, which announced a 12 percent rise in fourth quarter output on-year despite a big drop in the price of iron ore, shed 0.8 percent, while BHP Billiton also closed down by the same margin. Atlas Iron tanked 5.3 percent after the miner slashed its FY 2015 capital expenditure guidance due to challenging market conditions.
"While [the GDP data] is below the growth target, 7.4 percent isn't too far away and that suggests demand remains. Hence, it will have a positive effect in the short term, but it will still boil down to [iron ore] prices in the long run," John Wilson, stock broker at Morgans Financial, said.
Australia's banking sector is in focus, as ANZ Banking prepares to kick off a sale process for its vehicle and equipment finance business Esanda.

Alacer Gold and Evolution Mining closed up nearly 4 percent each as spot gold hovered near a four-month high. Gold stocks will remain the "flavor of the month" as traders see benefit in hedging out risks around central-bank-induced volatility, IG's chief market strategist Chris Weston noted.
