Soc Gen on USD/JPY: 105-115 for the rest of the year?

Yesterday the Bank of Japan bought an increased amount of government bonds in 3 to 5 year maturities

• BOJ lifts its purchase amounts of JGBs in 3 - 5 years

Société Générale, Kit Juckes:

• The BOJ really, really wants to convince markets that they aren't ditching the world's most accommodative monetary policy just yet.
• A faster pace of 3-5yr bond-buying is purely for show, but EUR/JPY bulls are encouraged.
• The question on everyone's lips over here is how hard the market will press the BOJ and whether they'll be forced to accept a lower USD/JPY range : 105-115 for the rest of the year?
