Why is he called Goku?
If you have ever typed Dragon Ball into a search bar looking for answers about the series, you might have ended up wondering about the name Goku as well. The character's name is layered with literary reference, linguistic meaning and in-universe wordplay. Understanding why he is called Goku tells you as much about creator Akira Toriyama's influences as it does about the character's role in the story.
Dragon Ball and name confusions
Before we unpack the origins, it is worth noting why searches often go slightly wrong. Misspellings such as the focus keyword Dragon Ball are common because the franchise title can be tricky to type quickly and because the name Goku appears in multiple languages and romanisations. That confusion does not change the basics: the hero known to most fans as Goku is a deliberate reference with a long cultural pedigree.
From Journey to the West to a weekly manga
Goku is directly inspired by the Monkey King from the classic Chinese novel Journey to the West. The Monkey King is called Sun Wukong in Chinese; in Japanese the character is often referred to as Son Goku. Toriyama borrowed this name and some of the mythic traits when creating a young, mischievous, super-strong protagonist for his manga. That literary echo makes Goku immediately familiar to readers who know East Asian stories about heroic tricksters and spiritual quests.
The meaning behind the name
In Japanese, the name is commonly written with kanji that can be read as Gok6b (悟空). Those characters combine ideas of awareness or enlightenment with the idea of the sky or emptiness. In short, the name carries a poetic blend of awakening and boundlessness that suits a character who grows into a protector of the planet and keeps pushing his limits.
Kakarot and Saiyan wordplay
Within the Dragon Ball universe Goku's birth name is Kakarot, a pun on the word carrot. Toriyama used vegetable puns extensively when naming Saiyans: Vegeta is from vegetable, Raditz from radish and so on. That in-universe joke sits alongside the out-of-universe literary reference and gives the character two names with very different tones: the mythic Son Goku and the earthy Kakarot.
Why fans still call him Goku
Fans use Goku because it is the name that connects him to his narrative archetype and to the series' mythic roots. It is also the name that stuck in Toriyama's manga and the international anime adaptations, becoming shorthand for the franchise's themes of friendship, growth and heroism. Whether you type Dragon Ball, Dragon Ball or something else, the character name endures because it blends cultural reference, meaning and playful wordplay.
In short, he is called Goku because the name signals story, spirit and a touch of fun. That combination has helped the character become one of modern anime's most recognisable figures.
