Japanese shares headed for their first decline in four days on thin volumes ahead of the U.K. vote on whether to stay in the European Union.
The Topix slid 1.1 percent to 1,279.62 at the trading break in Tokyo, paring a three-day rally. All but one of the 33 industry groups dropped on volumes 20 percent below the 30-day intraday average. The Nikkei 225 Stock Average lost 1 percent to 16,002.60.
Investors remain jittery ahead of Thursday’s U.K. referendum amid concern a vote to leave the EU could destabilize the global economy and push investors into haven assets such as the yen. While most polls are still split on the outcome, betting shops put the probability of a Brexit at about 26 percent, near the lowest level this month.
