TOKYO, Aug 16 (Reuters) - Japan's Nikkei dropped to a more than one-week low on Tuesday as selling accelerated in late trade after the dollar hit a one-month low against the yen.

The market also turned cautious before the release of a slew of U.S. economic data later in the day.

The Nikkei dropped 1.6 percent to 16,596.51, the lowest closing level since Aug. 5.

The broader Topix fell 1.4 percent to 1,298.47 and the JPX-Nikkei Index 400 declined 1.4 percent to 11,684.54.
