TOKYO, Sept 17 (Reuters) - Japan's Nikkei average rose 0.8 percent on Friday, drawing support from weakness in the yen after Japan's massive yen-selling this week.
But gains may be kept in check as investors watch if there will be further currency intervention, and as they will also probably be reluctant to actively take positions ahead of a three-day weekend at home, market players said.
The benchmark Nikkei <.N225> gained 72.15 points to 9,581.65. It ended the previous day flat after touching a five-week intraday high of 9,620.90.
The broader Topix <.TOPX> added 0.7 percent to 850.41. (Reporting by Aiko Hayashi; Editing by Edwina Gibbs)
