Comiket 109: Dates, Entry Release & Winter Plan

Quick Answer

Comic Market 109 is scheduled at Tokyo Big Sight from Tuesday, December 29 through Thursday, December 31, 2026. The official page lists circle exhibits from 10:30 to 16:00. Corporate booths run until 17:00 on days 1 and 2 and 16:00 on day 3. East Halls 4–6 will not be available because of major renovation work.

You can plan lodging and public transport now, but do not buy or infer C109 admission from C108 information. The committee says detailed C109 admission information will be released around early November, and the C109 web catalog is scheduled to open on November 6.

Best next action: reserve a changeable place to stay and choose a public-transport route, then set an early-November reminder to recheck the official C109 page before buying admission.

What Is Confirmed and What Is Not

The organizer currently links C108 admission pages only as references. They are not C109 products, prices or purchase instructions.

Step 1: Choose a Travel Base, Not an Entry Product

The official venue is Tokyo Big Sight in Ariake. The C109 page says visitors should use public transport and should not arrive by private car, motorcycle or bicycle. It also asks visitors to avoid taxis to reduce traffic around the venue.

Useful rail approaches include:

• Rinkai Line to Kokusai-tenjijo Station, about a seven-minute walk; and
• Yurikamome to Tokyo Big Sight Station, about a three-minute walk.

The organizer also lists Tokyo BRT and bus options, but schedules and crowd conditions can change. Choose a hotel from which at least two public-transport routes are realistic. A changeable reservation is safer than a cheaper non-changeable booking before C109 admission and day-by-day content are known.

Step 2: Do Not Treat C108 as a Ticket Guide

C108 was a separate summer edition. Its admission prices, wristbands, sales channels, entry times, queue rules and hall layout do not become C109 facts simply because the official C109 page links them for reference.

Until the C109 release:

• do not publish or rely on a C108 price as the C109 price;
• do not assume the same product names or sale dates;
• do not buy a resale item described only as “Comiket entry”;
• do not promise access to a particular hall or booth; and
• do not choose a day only from old program information.

The official page says the C109 system will follow the general form used for C102–C108, but exact C109 admission details still require the new release.

Step 3: Use November as a Required Checkpoint

The committee says general-admission details will be published around early November. It also states that the C109 web catalog will open on November 6. These are two different checks:

1. read the C109 admission page for the actual product, price, sale channel and entry conditions; and
2. use the C109 web catalog to compare the content scheduled for each day.

Do not assume all circles, genres or corporate content appear every day. The right day depends on the C109 catalog, not on C108 memories.

Step 4: Plan Around a Smaller East-Hall Footprint

Tokyo Big Sight's major renovation means East Halls 4–6 are unavailable for C109. The organizer says detailed hall use will be announced after circle applications are processed.

This does not prove that the event will be less crowded. It means the layout will differ and old maps should not be used. After the official map is released:

• identify the hall for your priority circles or booths;
• save the current official map offline;
• allow transfer time between areas;
• choose one or two priorities rather than a packed list; and
• check whether the final day closes earlier for your target area.

Step 5: Prepare for Winter and Long Outdoor Movement

Late December in Tokyo can be cold, especially while waiting or walking in exposed areas. Bring layers that can be removed indoors, comfortable shoes, a charged phone, an offline route, water and any medicines you normally need.

The organizer prohibits waiting near the venue from the previous day, including overnight. Plan a lawful morning arrival by public transport after the detailed entry schedule is released. Do not create your own queue time from old editions.

A Simple Three-Date Decision Plan

Now

• hold changeable lodging;
• decide your airport and Tokyo transport base;
• save the official C109 page; and
• leave December 29–31 available.

Early November

• read the C109 general-admission release;
• confirm price, product, sale channel and entry instructions;
• decide whether the trip still works; and
• buy only through the announced legitimate route.

November 6 and After

• open the C109 web catalog;
• compare days by your actual interests;
• update the venue route and daily schedule; and
• download the final official notices and map when available.

Plan B If Admission Does Not Work

If the correct entry product is unavailable, unaffordable or unclear, do not rely on resale or C108 materials. Cancel or change the flexible booking, use official online information, and choose another Tokyo winter activity.
