Yara Elementary School visits the 'Sweet Potato King'
Yara Elementary School students take notes during their social studies tour at the Kadena Marina on Okinawa, Japan, Sept. 7, 2010. More than 50 students visited the Tomb of Noguni Sokan, an Okinawan historical figure known for bringing the sweet potato from China to Okinawa, which saved the local people from starvation.
