TOKYO, Sept 18 (Reuters) - Tokyo's Nikkei average fell 1.2 percent on Friday, hurt by financials after consumer finance firm Aiful Corp said it would ask creditors to push back repayments, while exporters such as Advantest Corp lost steam after a strong run-up.
The fall came as investors took a breather after gains that pushed the Nikkei to end above its 25-day moving average the previous day, market players said. Trade was also cautious ahead of a five-day holiday from Sept. 19-23 in Japan.
The benchmark Nikkei slipped 128.39 points to 10,315.41, after gaining 1.7 percent on Thursday to hit a one-week closing high.
The broader Topix retreated 1 percent to 930.03. (Reporting by Aiko Hayashi)
