TOKYO, Sept 13 (Reuters) - Japan's Nikkei share average edged up in choppy trade on Tuesday, but the broader Topix ended flat as a solid yen and worries about possible policy moves by the central bank next week sapped risk appetite.
The Nikkei ended 0.3 percent higher at 16,729.04 points after staying in a narrow range throughout the day.
The broader Topix was flat at 1,322.99, with only 1.424 billion shares changing hands, the lowest since August 25. The JPX-Nikkei Index 400 also was flat at 11,870.74.
