TOKYO, Sept 15 (Reuters) - Japan's Nikkei average edged up 0.2 percent in choppy trade on Tuesday, buoyed by Canon Inc and other exporters as the yen held steady against the dollar, but worries that it may only be a brief respite limited gains.
Japan Airlines failed to add to gains made the previous day despite news that Air France-KLM was joining a list of suitors seeking a minority stake in the loss-making Japanese carrier.
The benchmark Nikkei rose 15.56 points to 10,217.62, after falling 2.3 percent the day before. The broader Topix dipped 0.2 percent to 932.52.
Trade was thin and choppy, with the benchmark venturing into negative territory at one stage when the dollar briefly fell back below 91 yen. (Reporting by Aiko Hayashi)
