The Nikkei share average declined 0.4 percent to 17,290.49.
China stocks finished weaker on Wednesday, with stronger industrial profits data countered by growing doubts over the sustainability of the recovery and concerns about a government crackdown on speculation in commodities markets.
The blue-chip CSI300 index fell 0.4 percent, to 3,165.92, while the Shanghai Composite Index also lost 0.4 percent, to 2,953.67 points.
Profits earned by Chinese industrial companies rose 11.1 percent in March from a year earlier, but the market shrugged off the upbeat data as a tentative economic recovery in the first quarter has been priced in, traders said.
