USDJPY is attempting to break out to the upside. However, this seems to be driven by JPY weakness, not USD strength. All USD pairs are heading down. This makes it unlikely that USDJPY will successfully break to the upside. I wouldn't short based on this, but I will avoid going long until USD starts to regain some strength. It is unlikely for a healthy trend to start on weakness.
Long term, the situation is still bullish according to Ichimoku. I'll wait for USD strength as a confluence before considering going long. Neutral for now.
