Tokyo shares closed lower on Friday, following a global market slide stemming from the lowered European economic outlook as well as receding hopes for smooth progress in US-China trade talks.
The benchmark Nikkei 225 index dropped 2.01 percent or 418.11 points to end at 20,333.17. Over the week, it was down 2.19 percent.
The broader Topix index lost 1.89 percent or 29.63 points to 1,539.40. Over the week, it was down 1.61 percent.
"Overall Tokyo shares were down due to concerns on the US-China trade dispute," Yoshihiro Ito, chief strategist at Okasan Online Securities, said in a commentary.
Ito added that investors were cautious because of overnight falls of US and European shares.
Investors also grew wary after the EU Commission said it expected growth of 1.3 percent in the eurozone this year, a significant cut from the 1.9 percent it predicted in November, citing risks including Brexit fears, Italian economic woes and the global trade war.
In Japan, players adjusted their positions and locked in profits ahead of a three-day weekend, Okasan added.
