The backpacks were to be distributed to new arrivals at the local orphanages and other children that Odawara Child Guidance center serves. Japan has around 580 children's centers that house around 30,000 children. As of January 11, 2011, over 100 donations inspired by Tiger Mask have been reported across Japan. After the two initial donations, many other orphanages and children's facilities began to receive copycat donations of backpacks. Some have also received toys, food, and money to help pay for new backpacks. In addition, parallels to other anime and manga concerning orphaned children have also crept into the donation phenomenon. Sometime during the night of March 17 - morning of March 18, three cars parked at an evacuation center in Yamadamachi, Iwate had their tanks filled up and two 20-liter containers of heating oil were left outside the center by an unknown person. An evacuee discovered the donation upon starting his car and noticing his fuel gauge go from nearly empty to full. The evacuee noted: "We had hardly any fuel left. We were in a real pinch. I'm so grateful for the donation. I reckon it was Tiger Mask." The evacuation center noted that they would use the heating oil during the night to conserve fuel due to the ongoing crisis. Other child welfare offices and agencies have reported increased, anonymous donations in the aftermath of the disaster. Because tax benefits for charitable donations are limited in Japan, a culture of charity donations has never really taken root. For example, the ratio of charitable donations by individuals in Japan is 52.5%, compared with 82.7% for the US. Also, Japanese culture emphasizes modesty, which means that Japanese people are generally reluctant to do good deeds in public view. Therefore, the Tiger Mask movement assuages both cultural inhibitions towards charitable deeds; it gives people in Japan a reason to donate while allowing them to do so anonymously. Several donators left notes purportedly from other fictional characters from franchises outside the Tiger Mask series. Notable characters who "donated" include Rei and Kaji from "Neon Genesis Evangelion", Haruhi Suzumiya, and Stitch. In April 2020, an anonymous donator left over 100 facemasks and other hygiene supplies at a nursing school in Ichinoseki, Iwate, claiming to be the character Inosuke Hashibira from the manga "".
