JPY review

Western Union notes in a report on Tuesday:

• Call your JPY buyer today with the strongest greenback since July 2007. The dollar briefly touched ¥122 against its Japanese counterpart as U.S. Treasury yields held near elevated levels, buoying the buck and signaling rising market confidence in a Fed rate hike this year. 
  
  
• Adding to the yen's woes, data this week showed a Japan's economy on a rockier footing as fourth quarter growth unexpectedly slowed to a 1.5 percent annual rise from an initial estimate of more than 2 percent. 
  
  
• The weaker shape of the world's third biggest economy keeps the door open to stronger stimulus from the Bank of Japan this year.
