Japan's Nikkei share average rose on Tuesday to end at its 200-day moving average after the Bank of Japan unexpectedly eased policy by increasing its asset-buying programme to help the economy mired in deflation and hurt by a strong yen.
The Japanese currency weakened against the dollar following the BOJ's announcement that it would add 10 trillion yen to its asset buying and lending scheme, under which it buys government and private debt and lends cheap funds against various types of collateral, to 65 trillion yen.
Exporters climbed, with Toyota Motor Corp up 1.8%, Canon Inc adding 1.5% and TDK Corp climbing 2%.
Real estate stocks were also in demand, with Sumitomo Reality & Development Co Ltd, Tokyu Land Corp and Mitsui Fudosan Co Ltd up between 3.6 and 5.1%.
The benchmark Nikkei advanced 0.6% to 9,052.07, a fresh three-month closing high.
The Nikkei volatility index shed 7.4%, indicating improving risk appetite among investors. The lower the volatility, the higher the risk appetite.
