In a Nutshell:
Cosplay as a practice began long before the word existed. Fans were dressing as fictional characters at science fiction conventions as early as the 1930s. The term “cosplay” itself was coined in 1984 in Japan, and the modern global cosplay community took shape in the decades that followed as fandoms, conventions and online spaces expanded.
Cosplay did not appear suddenly as a modern internet phenomenon. It developed gradually through fan culture, science fiction conventions, and evolving ideas about identity, performance and fandom. While the word “cosplay” itself is relatively recent, the act of dressing as fictional characters has roots that stretch back more than a century.
Understanding when cosplay was invented requires separating three related but distinct ideas: costumed fandom, the term cosplay, and the modern global cosplay community. Each emerged at a different time.
The earliest documented examples of people dressing as fictional characters for communal events date back to the early twentieth century. Science fiction fandom played a major role in this development.
In 1939, the first World Science Fiction Convention was held in New York City. Attendees Forrest J Ackerman and Myrtle R Douglas wore what they called “futuristicostumes,” inspired by science fiction imagery. Their outfits stood out and attracted attention, helping establish the idea that conventions could include costumed participation rather than passive attendance.
By the 1940s and 1950s, costume contests had become a regular feature at science fiction conventions. Fans began creating outfits inspired by characters, archetypes and speculative concepts. These early costumes were often homemade and varied widely in accuracy and style, but the core idea was present: embodying fictional worlds through dress.
At this stage, there was no unified term for the practice. It was simply part of fan culture.
The term “cosplay” was coined in Japan in the early 1980s. Japanese journalist Nobuyuki Takahashi attended the 1984 World Science Fiction Convention in Los Angeles. He observed fans wearing costumes of characters from science fiction and fantasy media and was struck by how central costume performance was to the fan experience.
When Takahashi wrote about the convention for Japanese audiences, he combined the English words “costume” and “play” into a new portmanteau: cosplay. The term captured both the visual and performative aspects of dressing as a character.
Cosplay quickly gained traction in Japan, particularly through anime, manga and video game fandoms. Unlike earlier Western costuming traditions, Japanese cosplay emphasized character accuracy, presentation and performance. Events specifically for cosplayers began to appear, and the practice became more organized and visible.
Japan provided fertile ground for cosplay to grow as a distinct cultural practice. The country already had strong traditions of costume, role performance and fan engagement. Manga and anime fandoms offered a constant stream of visually distinctive characters, which encouraged detailed costume recreation.
By the 1990s, cosplay had become a prominent part of conventions such as Comic Market, also known as Comiket. Dedicated cosplay spaces and rules emerged, formalizing the activity. Photography, craftsmanship and character portrayal became central components.
Importantly, cosplay in Japan was not limited to conventions. Public cosplay events, themed cafes and fashion subcultures blurred the line between costume and everyday clothing. This helped shift cosplay from a niche activity into a recognized cultural expression.
Cosplay began spreading globally in the 1990s and early 2000s as anime, video games and internet culture reached wider audiences. Western conventions expanded to include anime-focused events, and the Japanese term cosplay was adopted internationally.
Online communities played a major role in this expansion. Forums, early social media platforms and later image-based networks allowed cosplayers to share photos, tutorials and techniques. This accelerated skill development and raised expectations for costume quality.
As cosplay spread, it absorbed influences from multiple traditions. Western comic book fandom, Japanese anime culture, historical costuming and performance art all contributed to what cosplay looks like today. The result is a diverse global practice with no single style or standard.

While cosplay shares similarities with Halloween costumes and theatrical dress, it differs in key ways. Cosplay typically focuses on representing specific characters rather than generic archetypes. Accuracy, detail and intentionality are central concerns.
Cosplay also emphasizes community. Events, competitions and online platforms create shared standards and conversations around craftsmanship and interpretation. The goal is not simply to wear a costume, but to communicate understanding of a character.
This distinction is why cosplay is often treated as a separate practice rather than a subset of costume wearing.
Cosplay entered mainstream awareness in the late 2000s and 2010s. Large conventions like San Diego Comic Con began receiving media coverage that highlighted elaborate costumes. Celebrities, brands and fashion designers started referencing cosplay aesthetics.
Social media further normalized cosplay by making it visible outside of conventions. Platforms like Instagram and TikTok allowed cosplayers to reach large audiences, turning cosplay into both a hobby and, for some, a profession.
Despite this visibility, cosplay remains rooted in fan-driven creativity rather than commercial performance.
So when was cosplay invented? The practice of dressing as fictional characters in fan spaces dates back to at least the 1930s. The word cosplay was invented in 1984. Modern cosplay as a global, organized and highly visible activity emerged in the late twentieth and early twenty-first centuries.
Cosplay continues to evolve as media, technology and communities change. New materials, digital tools and platforms constantly reshape how costumes are made and shared. What remains consistent is the core impulse that has existed for decades: expressing connection to stories and characters through costume.
Cosplay was not invented in a single moment. It evolved from early fan costuming traditions, was named in the 1980s, and grew into a global cultural practice through shared media and community. What started as a small part of science fiction fandom is now a diverse, creative form of self-expression that continues to change alongside the stories and characters people love.
