Tokyo stocks fell Tuesday on selling to lock in gains after the Nikkei index climbed to a one-month high the previous day, as investors grew cautious ahead of a two-day U.S. Federal Reserve policy meeting.

The 225-issue Nikkei Stock Average ended down 126.18 points, or 0.43%, from Monday at 29,520.90. The broader Topix index of all First Section issues on the Tokyo Stock Exchange finished 13.05 points, or 0.64%, lower at 2,031.67.

Decliners were led by insurance, nonferrous metal and securities house issues.
