There are no major economic reports in Japan so USDJPY will be massively under the influence of the US reports.
The support rests at 103.590 with resistance at 104.070 which both lines are below the weekly pivot point at 104.190. The EMA of 10 is moving with bearish bias along the descendant channel and it is below the EMA of 200 and the EMA of 100. The Stochastic is moving in low ranges, the RSI is moving in oversold area. The MACD is moving in negative territory and the ADX is showing sell signal.
The support line seems too strong to be broken. In case of price growth buyers can expect the upper Bollinger band at 104.800.
