Japanese vending machines accepting Donations

"Tohoku Fukushi University campus in the Miyagi Prefecture is currently installing vending machines that allow the user to donate their change to charity. The drinks machine has two buttons; one for a 10 yen donation and another for 100 yen. These buttons can either be pushed after you make a purchase, taking the donation out of your change, or without buying anything at all if you’re feeling particularly generous." This is a great idea!! (via Plastic Bamboo). link
