Invite for the Shiblings is part of the TOMODACHI Initiative:
From Sec. Clinton's comments
"That’s why we are working to create opportunities for the young people in both of our countries. Our shared goal is to promote a tomodachi or friendship generation of young people who will be our future leaders. That’s why we have created a private-public partnership, the TOMODACHI Initiative, to bring young people from both countries together. We are looking forward to receiving hundreds of young Japanese students and sending hundreds of young American students, through student exchanges, sports programs, and entrepreneurial programs."
