The weekly chart indicates that USD/JPY price will go up to 133 level for closing the gap formed in 2002. Also the MACD confirms an uptrend in the next months. In my opinion, a good strategy for long term would be to buy this pair until at least 133 level.
The price on daily chart is still above EMA 55 and this is a confirmation for uptrend in medium term. Even if in short term can be a small retracement, in medium term this pair is still in uptrend. The uptrend is confirmed also by the positive MACD.
