I do not believe the BOJ will make the same mistake they made before (intervening on a Sunday-US evening seeking maximum effect in lower liquidity conditions). I do believe after they intervene the market will go right back to buying Yen pairs, especially AudJpy and UsdJpy due to rate differentials and Aussie economy, but not until a lot of damage is done. The rest of this week is not a good time to be long Yen pairs even if purely from a risk management approach.
