BoJ will release its quarterly Tankan survey of business sentiment overnight and it is expected to evidence an improvement in business confidence.  BoJ's Policy Board convenes on 14 October and 30 October and will publish its twice-yearly economic growth and inflation forecasts at the latter.  Finance minister Fukii reported he will not discuss currencies at the Group of Seven meeting in Istanbul this weekend.  Data released in Japan overnight saw August construction orders decline 25.2% y/y while August overall housing starts were off 38.3% y/y.  Additionally, August industrial output was up 1.8% m/m and manufacturing PMI rose to 54.5.  Dealers continue to cite continued yen repatriation flows even on the last day of Japan's fiscal year-end.  The Nikkei 225 stock index climbed 0.33% to close at ¥10,133.23.  U.S. dollar offers are cited around the ¥94.75 level.  The euro moved lower vis-à-vis the yen as the single currency tested bids around the ¥130.60 level and was capped around the ¥132.00 figure.  The British pound moved lower vis-à-vis the yen as sterling tested bids around the ¥142.85 level while the Swiss franc moved lower vis-à-vis the yen and tested offers around the ¥85.90 level.
