U.S. Air Force Col. Timothy Sundvall, 35th Fighter Wing commander, swings a wooden mallet as his family watches during the annual Mochi Pounding Ceremony at a Japan Air-Self Defense Force facility at Misawa Air Base, Japan, Dec. 15, 2014. Mochi, or rice cake, is traditionally made to celebrate the New Year. As the process of making this treat is considered difficult, it is done every year as a symbol of the teamwork and strong ties between America and Japan. (U.S. Air Force photo by Staff Sgt.
