UsdJpy- to 105 in the next week?

After reaching the resistance area from 112 on March 25, UsdJpy is trading downward forming a descending triangle. The support is in 107.00-107.30 area and the pair seems to force this support and is clear that it lacks buying power.
I believe this support will give up next week and the pair could easily drop 200 pips to the next important support at 105.
I'm looking to sell this pair for a 1:2 risk: reward
