Where Does the Name "Kamen Rider" Actually Come From?
The grasshopper-masked hero has a name with a simple, literal origin — but the design behind it has a stranger history than most fans realize.
A Simple Name, A Stranger Backstory
"Kamen Rider" is about as literal a name as tokusatsu gets: kamen (仮面) means mask, and Rider refers to the character's motorcycle. Put together, it describes exactly what Takeshi Hongo is when the series begins in 1971 — a masked man on a motorcycle. What's less obvious to newer fans searching for the origin of the Kamen Rider name is how that mask design came to be, and why a grasshopper of all things became the face of one of the longest-running tokusatsu franchises in history.
From Skull Man to Grasshopper
Kamen Rider began as a planned adaptation of creator Shotaro Ishinomori's earlier manga Skull Man, which, as the name suggests, featured a hero with a skull motif. During development, Ishinomori and director Toru Hirayama redesigned the lead character away from the skull concept and toward an insect motif, ultimately landing on a grasshopper. The grasshopper design gave the character compound eyes, a segmented look, and a silhouette distinct from any hero on Japanese television at the time.
The choice wasn't arbitrary flavor. Grasshoppers are fast, they leap rather than simply run, and their design gave the show's stunt choreography a visual hook — Kamen Rider's jump kick became one of the character's signature moves, tying directly back to the insect the mask was modeled on. That grasshopper-derived athleticism became a core part of the Kamen Rider identity, distinguishing the character from the more armored, robotic aesthetic that later Metal Hero shows would adopt.
Takeshi Hongo, the First Kamen Rider
In the show's premise, Takeshi Hongo is a university student and motorcycle racer who is kidnapped and forcibly cyberized by the villainous organization Shocker, which intends to use him as a weapon against humanity. Hongo breaks free before the brainwashing is complete and turns Shocker's own technology against it, using his enhanced, insect-based physiology to fight back as Kamen Rider. That premise — a modified human turning their captor's technology against them, and fighting the organization that created them — became a structural template the franchise has returned to across more than fifty years and dozens of series, from Shocker's kaijin foot soldiers in 1971 to the various evil organizations every Rider protagonist has faced since.
How the Grasshopper Motif Shaped Later Riders
Even as the franchise moved away from strict insect motifs, the DNA of that original grasshopper design persisted. Compound-eye visors, segmented body armor, and insect-inspired proportions recur throughout the Showa and Heisei eras, even in Riders themed around completely different concepts. It's a design lineage that fans researching Kamen Rider history often trace directly back to that first redesign decision in 1971, when the choice between a skull and a grasshopper effectively decided what the entire franchise would look like for the next half-century.
A Name That Outlived Its Era
Every Kamen Rider series since 1971, all the way through the current Reiwa-era shows, keeps the name even as the actual masks have moved from grasshopper to books, cards, snack food, and dream imagery. The literal meaning — a masked rider — has stayed constant even as almost everything else about the design language has changed generation to generation. It's a small piece of trivia, but it's a useful reminder of how much the modern, gadget-driven Kamen Rider aesthetic owes to a single insect redesign decision made more than fifty years ago.
