Article

Comic Market 109 (C109) will run for three days — December 29-31, 2026 — at Tokyo Big Sight, marking the event's first 3-day edition since C97 in 2019.

Why Three Days This Time

Per currently available reporting from the Comic Market Preparatory Committee (via secondary coverage), the extension to three days reflects a combination of factors: Tokyo Big Sight's large-scale renovation continuing to reduce available hall space through the end of 2026, and recent years showing higher circle-application volume for winter Comic Market than for the summer edition.

Hall Allocation

Per the official Comic Market Preparatory Committee C109 info page (comiket.co.jp), East Halls 4, 5, and 6 remain unavailable due to the ongoing Tokyo Big Sight renovation — the same constraint that affected the prior C108 event. For the halls that ARE available, the official page lists: circles (サークル) across East Halls 1-3, West Halls 1-2, and South Halls 1-2; corporate booths (企業ブース) in West Halls 3-4 and South Halls 3-4; and the cosplay area in East Hall 8 and the 2nd-floor exhibition space. The official page explicitly notes this allocation may still change depending on final circle application numbers ("ホールの使い方は、サークル申込数によっても変わりますので、現時点では未定です"), so this should be read as the current official plan rather than a permanently fixed layout.

Hours and Admission

Per the official page, circle-booth hours run 10:30 AM-4:00 PM, and corporate-booth hours run 10:30 AM-5:00 PM (4:00 PM on the final day). Circle online applications ran August 10-23, 2026, with the mail-in application window August 10-19 (postmark valid). The official page does not itself list general-admission ticket pricing — that information is covered on the Comic Market site's general-admission pages, which were not part of this article's direct verification.

More About This Event

• First 3-day Comic Market since C97 in 2019.
• East Halls 4, 5, and 6 unavailable due to Tokyo Big Sight's ongoing large-scale renovation.

Tickets

The official C109 info page covers circle/corporate/cosplay logistics, not general-admission ticket pricing; general-admission ticket pricing and sales dates were not independently verified for this article.

Access

Tokyo Big Sight, 3-11-1 Ariake, Koto-ku, Tokyo. East Halls 4, 5, and 6 are unavailable due to renovation. Circles: East 1-3, West 1-2, South 1-2. Corporate booths: West 3-4, South 3-4. Cosplay: East Hall 8, 2nd-floor exhibition space. Allocation confirmed on the official site as current but subject to change with final circle application numbers.

What To Know

A 3-day Comic Market is a genuinely rare event — the first since C97 in 2019 — making C109 a notable milestone for the doujinshi/fan-creator community regardless of any individual circle's plans, and worth flagging well ahead of the event given Tokyo Big Sight's ongoing hall-availability disruption.

Comic Market has historically run as a 2-day event in recent years; the return to 3 days for C109 is reported to reflect both continued hall reductions from Tokyo Big Sight's large-scale renovation (expected to continue through the end of 2026) and higher recent winter circle-application volume compared to summer. This article verifies the C109-specific hall allocation directly from the Comic Market Preparatory Committee's own official C109 info page, rather than assuming it matches the prior C108 event (the two editions share the same East 4-6 closure, but C109's circle/corporate/cosplay hall assignments were independently confirmed, not copied from C108).
