The yen advanced against its peers on Thursday as persistent U.S.-China trade fears and Brexit concerns fanned risk aversion, lifting the safe-haven Japanese currency.
The yen was 0.1% firmer at 110.240 to the dollar, having pulled back from a two-week low of 110.675 plumbed on Tuesday.
The Japanese currency also rose modestly against the euro, pound and Australian dollar, adding to overnight gains.
The pound was little changed at $1.2663 after slipping to $1.2625 overnight, its lowest since Jan. 4.
The dollar index against a basket of six major currencies was steady at 98.064, its rise earlier in the week to a one-month high of 98.134 stalling as U.S. yields declined amid the risk aversion.
The euro was flat at $1.1154, in close range of a 2-1/2-week low of $1.1142 brushed on Tuesday ahead of the May 23-26 European parliamentary election.
The Swiss franc, a safe-haven along with the yen, was a shade higher at 1.009 francs per dollar after advancing 0.15% on Wednesday.
The Australian dollar nudged down 0.1% to $0.6876.
