USDJPY: Is there buyer at high price?

USDJPY still in uptrend and it already touches ¥140, now seems like going to make some pullback/correction wave down to ¥138 towards SNR (RBS) zone. I'm looking for bounce from this level. I'm consider to buy at ¥138 with stop loss at ¥137.4 (60 pips), target/TP1 at ¥140 (200 pips), TP2 at ¥142 (400 pips), minimum RRR 1:3. Buy at "seller zone" (¥138) is quite risky. For safer entry better wait the price break trendline from those minor swing highs. This maybe still need 1~2 week for the price to hit this level. For sure, always take fundamental data into consideration for main reason to entry.
What you guys think?
