The 225-issue Nikkei Stock Average dropped 35.62 points, or 0.23 percent, from Wednesday to 15,343.37.
The broader Topix index of all First Section issues on the Tokyo Stock Exchange, meanwhile, lost 2.96 points, or 0.24 percent, to 1,231.24.
Notable issues that retreated by the break comprised real estate, information and communication and construction-linked shares.
