The Japanese yen edged down on Tuesday after the Bank of Japan (BOJ) held policy steady, shedding some gains made following deadly incidents in Germany and Turkey, while regional stocks were mixed after Federal Reserve Chair Janet Yellen's upbeat comments.
The BOJ maintained its pledge to guide short-term rates at minus 0.1 percent and the 10-year government bond yield around zero percent while offering a more upbeat view of the economy than in its November 1 assessment.
Stating that the economy continues to recover moderately as a trend, the central bank signalled its conviction that a generally weak yen and a rebound in overseas demand will lift prospects for a solid recovery.

Wall Street ended higher on Monday, albeit below the session's highs, as optimism over Yellen's comments about the U.S. labour market offset some of the risk aversion following the deaths in Germany and Turkey.
"Yellen painted a very positive picture in her commentary overnight," said James Woods, global investment strategist at Rivkin Securities in Sydney.
"The (Federal Open Market Committee) has done a fantastic job preparing the market for this second and subsequent hikes. Importantly they have continued to stress that the FOMC remains data dependent, only hiking when the underlying fundamentals of the economy support this."
Still, markets were rattled after a truck ploughed into a crowded Christmas market in central Berlin Monday evening, killing 12 people and injuring 48 others in what Germany's interior minister said looked like an attack.
