Tiger Mask donation phenomenon

The Tiger Mask donation phenomenon is a series of donations of randoseru (school backpacks) and other items to orphanages around Japan. The first donation happened when someone left ten 30,000-yen backpacks at a child guidance center in Gunma Prefecture on Christmas Day in 2010. A note attached to the bags was signed "Naoto Date", the real name of the titular character of Tiger Mask, a popular 1960s and 1970s manga about a wrestler who fought for orphans, being raised in an orphanage himself. Since the initial donation, copycat donations have appeared around Japan at various facilities for children, ranging from more backpacks to toys, food, and monetary gifts.
