This pair has been drifting sideways over the last week.  79.65 has been supporting the USDJPY but lower yields in the US  have not been helping its case.  The pair is still in a channel heading lower and until the cross can break above channel trend line resistance, my view has to be for a move even lower.  Support is at 79.65 followed by 79 and resistance is up at 80.35.

Sup     79.65             79

Res     80.35
