1) USDJPY follows stocks (particularly the Nikkei) and stocks are faltering
2) Stocks are faltering for several reasons 1. Article 50 next week 2. Trump is not getting anything done(at least up to now) 3. French elections and risk of Euro unfriendly candidate winning 4. USD is weakening lately. 5. USD did not respond favorably to Mondays hawkish Fed speak.
3) USDJPY is still way above where it was on US election day so it still has far to fall.
