After touching 79.14 key support, USDJPY rebounds strongly, suggesting that a cycle bottom has been formed on 4-hour chart. Further rise to test 80.09 resistance would likely be seen, a break above this level will signal resumption of the uptrend from 77.66, then another rise towards 82.00 could be seen. On the other side, a clear break below 79.14 key support will confirm that the uptrend from 77.66 had completed at 80.62 already, then further decline to 78.00 area could be seen.
