Potential triangle breakout for a long position

FX:USDJPY   U.S. Dollar / Japanese Yen
A triangle in $USDJPY seems to have formed with the upwards momentum looking to break to retest the high from early December. A breakout will occur at 120.60, and then confirmation would be sough for around 120.80 (the high of the triangle formation). After 121.80 is the next target.
