The central bank also reiterated that the world's third-biggest economy is recovering moderately.
Asian markets were seemingly unaffected by the weaker finish overnight in the U.S. as investors eyed continued gains in oil and the U.S. dollar ahead of the unofficial start of earnings season on Wednesday. The Dow Jones Industrial Average finished in neutral territory, while the S&P 500 and Nasdaq Composite ticked down 0.2 and 0.1 percent each.

Japan's Nikkei 225 hit its highest level since June 2000, while the dollar-yen (Exchange:JPY=) fell as low as 119.90 against the U.S. dollar, after the BoJ held its monetary policy unchanged.
Tokyo-based pharmaceutical company Eisai (Tokyo Stock Exchange: 4523.T-JP) rallied 2.2 percent after it was granted an additional patent for its Belviq drug. Following the news, Eisai's U.S. partner Arena Pharmaceuticals (ARNA) bolstered 3.9 percent overnight on the Nasdaq.
