Japanese stocks ended their trading year in negative territory on Friday.
The Nikkei 225 and Topix index both struggled for gains on the day: The former slipped 0.31 percent to close at 20,014.77 while the latter shed 0.5 percent to finish its trading week at 1,494.09. The declines came on the back of two straight days of gains for both indexes.
Those losses saw the Nikkei 225 post its first annual loss since 2011. The Topix also booked its largest annual loss since 2011, according to Reuters. The Japanese markets are closed next Monday, making Friday their final trading day of 2018.
The moves in Japan came after the country's central bank released its summary of opinions from its December monetary policy meeting, where it noted the "heightening" of downside risks to economic activity.
"Regarding the outlook for the global economy, risks have been tilted to the downside on the whole amid heightening uncertainties and a prevailing view that such situation will be protracted," said the note from the Bank of Japan.
Japan's industrial output also declined in November, registering a 1.1 percent fall as compared with the previous month. The country's jobless rate also increased to 2.5 percent in November, as compared to 2.4 percent in October, according to data from the Ministry of Internal Affairs and Communications.
