Just long UJ at the described firstname.lastname@example.org.. I will make my further follow up with comments.
The greenback performs quite weak recently due to bad NFP on the last Friday and pushes the JPY to strengtheners. Anyway according to technical point of view the price zone at around 106.xxx finds a larger demand since April 2016 up to now, in this sense we go long with USDJPY today at the level of 107.120 with around 100 pips stop loss but for t/p will be some hundreds pips. Once USDJPY finds its rally on the upside, then the up momentum will be very strong.
