At 2350GMT we get the weekly flow of capital figures, for the week ending May 17:

Japan Buying Foreign Bonds (prior week was +Y186.4B)
Japan Buying Foreign Stocks (prior week was +Y19.2B)
Foreign Buying Japan Bonds (prior week was -Y413.5B)
Foreign Buying Japan Stocks (prior week was Y878.8B)

Again, the market will be paying most attention to the “Japan Buying Foreign Bonds” release, to try to ascertain the movement of Japanese capital out of domestic, and into foreign, bonds. Increases in his number could precipitate a higher USD/JPY.
