Comic Market 109 (C109): December 29-31 at Tokyo Big Sight — Its First 3-Day Event in Nearly 5 Years

Article

The world's largest doujinshi convention has confirmed its winter dates — and for the first time in nearly five years, it's back to a full three-day event.

Dates and Venue

Comic Market 109 (C109) runs December 29 (Tuesday) through December 31 (Thursday), 2026, at Tokyo Big Sight.

A Return to Three Days

This is Comiket's first three-day event in nearly five years, since the event's scale was reduced during the COVID-19 pandemic — a meaningful signal of the convention's continued return to its pre-pandemic footprint.

Venue Note

East Halls 4 through 6 at Tokyo Big Sight will not be available for this event due to ongoing renovation work — worth factoring in if you're planning your route through the venue.

What To Know

Comiket returning to a full three-day event for the first time in years is a genuinely significant milestone for the doujin (fan-creator) community worldwide — it signals a real return to pre-pandemic scale, and for international fans planning a Japan trip specifically around doujin culture, exact dates this far out make serious trip planning possible.

同人誌 (doujinshi) refers to self-published works — often derivative fan works, but also entirely original comics and novels — sold directly by their creators, and Comiket is the event where Japan's doujin creator economy is most visible at scale; the venue's hall availability (East 4-6 closed for renovation) is a genuinely practical detail worth knowing if you're planning which circles or areas to prioritize.

What Fans Are Saying

• "3 full days again, finally!"
• "Already planning my December Tokyo trip around this."
• "Good to know about the East Hall closure ahead of time."
