Since its debut, the Dragon Ball franchise by Akira Toriyama has had a considerable impact on global popular culture.[1][2] In 2015, the Japan Anniversary Association officially declared May 9 as "Goku Day" (悟空の日, Gokū no Hi) after the main character; in Japanese, the numbers five and nine can be pronounced as "Go" and "Ku".[3] It is similarly influential in international popular culture across other parts of the world.[1] Dragon Ball is widely referenced in American popular culture, from television and music to celebrities and athletes, and the show has been celebrated with Goku making an appearance at multiple Macy's Thanksgiving Day Parades,[4] and with murals based on Dragon Ball appearing in cities such as Los Angeles, Chicago, Kansas City, and Denver.[2]
