Tokyo stocks ended a three-day winning streak Monday as investors await developments from Bank of Japan and US Federal Reserve meetings this week.
The benchmark Nikkei 225 at the Tokyo Stock Exchange, which on Friday ended above 19,000 points for the first time in 15 years, edged down 0.04 percent, or 8.19 points, to finish at 19,246.06.
The broader Topix index of all first section shares fell 0.14 percent, or 2.12 points, to 1,558.21.
Tokyo moved in and out of negative territory during the session, after New York declined Friday on renewed concerns about falling oil prices and the impact of a stronger dollar on US firms.
Investors are now focusing on the outcome of the Federal Reserve's policy meeting this week, hoping it will give a clearer timeline for when it will raise interest rates as the US economy strengthens.
Investors are also eyeing the start of a BoJ meeting, which wraps up Tuesday, although few expect Japanese policymakers to announce fresh measures until later this year.
"According to standard expectations there will probably be no major BoJ actions, but as they tend to move when you're least expecting it, it's difficult to tell," Shoji Hirakawa, chief equity strategist at Okasan Securities, told Bloomberg News.
Japan's central bank surprised markets in October when it expanded its already huge asset-buying plan to try to kickstart the world's number three economy.
