Because of the 2011 Tōhoku earthquake and tsunami, Gackt founded the "Show Your Heart" charity for collecting money to buy supplies for the victims. Many Japanese and Asian musicians and singers, actors, designers, sportspeople, and other entertainers joined Gackt's initiative. In March 2011, Gackt sent a truck convoy with 72,000 lb (33,000 kg) of food and clothes. He also held a street corner fund-raising campaign in over 130 locations all across Japan at the same time, collecting ¥25,234,490 (or US$320,193). All money collected through bank transfers and street fundraising activities was transferred to the Japanese Red Cross, totalling ¥208,181,735 (US$2,641,564).
In May 2011, it was announced that Gackt would start a new tour called the "World Tour *Show Your Soul.I*" under the Yellow Fried Chickenz moniker, with new band members and songs, including visits in France, Germany, the Netherlands, the United Kingdom, Spain, Hungary, Poland, Sweden, and Russia. On September 14, he began a Japanese nationwide tour. Part of the world tour revenue would be donated to the Japanese Red Cross.
On August 22, he participated in 86th "Great Kenshin Festival", playing the role of Uesugi Kenshin for the fourth time.
On November 30, 2011, Gackt released his 40th single titled "GRAFFITI". It is used as the current opening theme for the anime Sket Dance.
