The world’s largest fan-organised event, and the central piece of infrastructure of the Japanese doujinshi economy. Comiket has run continuously since 1975, expanding from a 32-circle small-room event to the contemporary 30,000+-circle Tokyo Big Sight event with hundreds of thousands of attendees. The convention’s continuity and scale make it a singular case in international fan-culture history.

Overview

Comic Market (Comiket, Komike) is the world’s largest doujinshi convention, held twice yearly (summer in mid-August, winter in late December) at Tokyo Big Sight in Koto Ward, Tokyo. The convention runs three to four days per session, with approximately 30,000 participating circles and cumulative attendance of 500,000–700,000 per session. The 1975 founding makes Comiket older than virtually any comparable fan-organised convention internationally, and the continuity of operation across five decades is itself a defining feature of the event.

The convention operates as a tripartite structure: participating circles (creators or creator groups) lease space and sell self-published works directly; general attendees purchase works from the circles; corporate booths (publishers, game companies, and other commercial entities) operate alongside the circle areas. The combination produces a single event-space in which the doujin commercial economy and the wider commercial publishing/game industries intersect.

The majority of participating circles produce second-creation (nijisousaku) work — doujinshi based on existing commercial properties — with original-creation, hyouron (critical-writing), doujin game, and other categories making up the remainder. Adult doujinshi has historically been a substantial portion of the participating-circle base, and Comiket is the principal distribution channel for the wider Japanese-language adult doujin economy.

Founding (1975)

The first Comic Market was held on 21 December 1975 at the Japan Fire Service Building in Toranomon, Tokyo’s Minato Ward. The event ran in a meeting room with 32 participating circles and approximately 700 attendees, organised by the criticism collective Meikyu ‘75 (Atei Jun, Harada Hisao, Yonezawa Yoshihiro, Takamiya Naruko, Shikishiro Kyotaro). The founding motivation, articulated in subsequent reflection by Yonezawa Yoshihiro (the second-generation principal), was to create a convention space alternative to the existing manga conventions (mid-1970s events such as Manga World and the Nihon Manga Taikai), with stronger participant orientation and openness to alternative critical perspectives.

The founding figures emphasised that the new convention would centre creation and criticism in dialogue, not commercial-publishing-industry consumption. The principle has remained constitutive of Comiket’s organisational structure through the subsequent decades, even as the scale and commercial integration have expanded substantially.

Expansion (1976–1995)

Comiket scaled up steadily through the late 1970s, 1980s, and 1990s. Venue moves followed: in 1979 the Tokyo Distribution Centre at Harumi; in 1981 the Harumi Exhibition Hall (Tokyo International Trade Fair Hall). By the late 1980s the convention had passed 10,000 participating circles, with substantial growth driven by the 1980s manga and anime boom — Captain Tsubasa, Sailor Moon, and similar properties produced second-creation circles in large numbers.

The 1995 cultural impact of Neon Genesis Evangelion drove particularly substantial expansion. The summer 1995 C48 passed 20,000 participating circles for the first time, approaching the physical capacity of the Harumi Exhibition Hall. The need for a larger venue became urgent.

Tokyo Big Sight era (1996–present)

In summer 1996, the C50 moved to the newly-opened Tokyo International Exhibition Centre at Big Sight in Koto Ward. The move provided the physical capacity for 30,000-circle operation across the full East Halls; the convention has remained at Big Sight since. From the late 1990s, corporate booths expanded substantially, with the wider anime and game industries integrating their major-release marketing with the Comiket calendar.

From the 2010s, the West and South Halls also entered use, and the convention extended to four days from C97 (Winter 2019). Paid entry was introduced from the same period, with wristband-based entry charged at roughly 1,000 yen, with the revenue used to fund the convention’s operational expansion.

COVID-19 era (2020–2022)

Spring 2020’s C98 was the first cancellation in Comiket’s history, in response to the COVID-19 pandemic. The 2021 C99 operated under capacity and attendance limits, and 2022’s C100 resumed near-normal operation. The pandemic-period disruption was a substantial test of the convention’s operational structure, with the Preparatory Committee’s organisational continuity and the volunteer-staff base proving resilient.

Current state (2023–)

The 2024 and 2025 sessions have substantially recovered to near-pre-pandemic scale. Persistent issues include: the generational shift in doujin consumption as younger consumers move toward digital distribution; rising print and shipping costs that affect circle economics; and the wider question of the convention’s adaptation to mature-era infrastructure constraints. The 2025 fiftieth-anniversary programme has been the principal recent commemorative project.

Organisational structure

The Comic Market Preparatory Committee operates as a voluntary unincorporated association, with several hundred volunteer staff responsible for venue operation, circle selection, problem resolution, and continuous self-regulation review. Following Yonezawa Yoshihiro’s death in 2006, the Committee operates under a collective-leadership system rather than a single-named principal.

Circle participation operates on an application basis, with applications substantially exceeding the available capacity (the standard application-to-capacity ratio is 1.5–2). General attendees enter under the wristband-paid system from C97 onward, with the entry-day system used to distribute attendance across multiple days.

Doujin distribution role

Comiket is the largest distribution event for paper doujinshi in Japan. For participating circles, Comiket operates as the annual production-cycle release point; for consumers, the convention operates as the principal access point for paper doujinshi. The supplementary distribution pipeline — through specialist retailers (Toranoana, Melonbooks) and DLsite’s digital distribution — operates in parallel with the convention, with the supplementary channels expanding the audience reach beyond the convention attendees.

Adult second-creation doujinshi is a substantial portion of the participating circles, and Comiket is the principal release event for the adult doujinshi production cycle. The Preparatory Committee’s self-regulation guidance covers adult-content circulation, with the standard adult-content production conventions (genital obscuration under Article 175 compliance) applied at the print-shop level.

Copyright and regulatory context

The second-creation doujinshi circulated at Comiket is, in formal copyright-law terms, potentially infringing of copyright (the adaptation and reproduction rights of the underlying work). The wider Japanese practice has been one of implicit tolerance (mokunin) by the underlying-property holders and commercial publishers, with the result that large-scale infringement-enforcement action against doujinshi has been rare. The 2018 copyright-law reform under TPP-related implementation legislation introduced non-complaint (hi-shinkokuzai) treatment for a subset of infringement, but established working arrangements have continued to operate the doujinshi market in practical terms.

For adult content, the obscenity-distribution offence (Article 175) and the prefectural Youth Protection Ordinances apply. Print-shop and convention-level self-regulation operate the practical compliance regime, with industry-standard genital-obscuration the working standard for circulation.

Cultural and academic reception

Comiket has been the subject of substantial academic and cultural analysis, both Japanese-language and international. The Preparatory Committee’s own Comic Market 30s File (2005) provides the principal historical record of the convention’s first thirty years. Sharon Kinsella’s Adult Manga (2000), Patrick W. Galbraith and Androniki Christodoulou’s Otaku Spaces (2012), and the wider English-language work on Japanese fan culture have treated Comiket as a principal site of analysis.

The convention’s particular position — at the intersection of fan culture, copyright pragmatics, adult-content circulation, and commercial-industry marketing — makes it a recurring reference point in the study of Japanese popular culture and the cultural economy of postwar Japan.
