Two train stations provide the main rail access to Tokyo Big Sight, and choosing the better one can make your trip to Comic Market 108 much simpler. Kokusai-tenjijo Station is on the Rinkai Line, while Tokyo Big Sight Station is on the Yurikamome Line.
This guide focuses only on transportation: which line to use, where to transfer, how to travel from major Tokyo areas and airports, and how to prepare a backup route for the trip home. For admission choices and wristband procedures, use the C108 tickets and entry guide.
C108 takes place on August 15 and 16, 2026. Train operations, airport bus schedules, station restrictions, and event-day directions can change, so check the official sources again shortly before your visit. Last checked: July 29, 2026.
The 30-Second Answer
- Use the Rinkai Line to Kokusai-tenjijo Station if you are coming from Shinjuku, Shibuya, Ikebukuro, Osaki, Oimachi, or Shin-kiba.
- Use the Yurikamome Line to Tokyo Big Sight Station if you are coming through Shimbashi or Toyosu.
- Kokusai-tenjijo Station is about a seven-minute walk from Tokyo Big Sight. Tokyo Big Sight Station is about a three-minute walk away under normal conditions.
- AM e-ticket holders should pay special attention to the Rinkai Line because the official C108 instructions place the wristband exchange near the Rinkai Line station after 8:00.
- Save one route using each line. Your best return route may be different from your morning route.
- Use public transportation. Tokyo Big Sight warns that nearby roads and parking areas are expected to be congested.
Your Two Main Stations
Kokusai-tenjijo Station on the Rinkai Line
Kokusai-tenjijo Station is about a seven-minute walk from Tokyo Big Sight according to the venue. The Rinkai Line runs between Osaki and Shin-kiba, with Kokusai-tenjijo between them. Every Rinkai Line train stops at Kokusai-tenjijo.
This line is usually the most direct rail choice from the west side of central Tokyo. Some JR Saikyo Line trains continue onto the Rinkai Line, allowing a no-transfer ride from stations such as Ikebukuro, Shinjuku, and Shibuya. Not every Saikyo Line train continues to the Rinkai Line, so check the destination display. If your train ends before entering the Rinkai Line, transfer at Osaki.
The venue lists about 14 minutes from Osaki to Kokusai-tenjijo and about five minutes from Shin-kiba to Kokusai-tenjijo. These are line-segment estimates, not total trip times. Add time for your first train, transfers, platform movement, waiting, and event-day crowds.
Tokyo Big Sight Station on the Yurikamome Line
Tokyo Big Sight Station is about a three-minute walk from the venue under normal conditions. The Yurikamome connects Shimbashi and Toyosu through the waterfront area. The venue lists about 23 minutes from Shimbashi and about nine minutes from Toyosu to Tokyo Big Sight Station.
This route is useful when you are staying near Shimbashi or Toyosu, or when your train connects easily to either station. It also gives you a practical alternative when the Rinkai Line is disrupted or heavily congested. The shorter normal walk from the station can help, but C108 crowd control may change the route you actually follow after leaving the ticket gate.
Which Line Should You Choose?
Choose by your starting area and number of transfers, not only by the final walking distance. A three-minute station walk does not automatically make the Yurikamome faster if reaching Shimbashi or Toyosu requires several extra transfers. In the same way, a direct Saikyo–Rinkai train can be convenient, but only when its destination continues onto the Rinkai Line.
AM e-ticket holders have an additional reason to consider the Rinkai Line. The official C108 ticket instructions say that the QR code is exchanged for a physical wristband after 8:00 near the Rinkai Line station, and they recommend using the Rinkai Line. Save the newest C108 information map because the exact exchange and waiting-line directions can change.
If you already have a physical wristband or use another admission type, follow the entrance directions for that product. Transportation and admission are connected, but they are not the same decision. Do not assume that the crowd outside a station is the correct line for your admission type.
Routes from Shinjuku, Shibuya, and Ikebukuro
Look for a JR Saikyo Line train that continues onto the Rinkai Line toward Shin-kiba. When the service is direct, you can remain on the same train through Osaki and get off at Kokusai-tenjijo. Check both the platform display and the train destination before boarding.
If the next train does not continue onto the Rinkai Line, take an appropriate JR train to Osaki and transfer there to a Rinkai Line train toward Shin-kiba. Do not assume that every train using a Saikyo Line platform goes to Kokusai-tenjijo.
For the return trip, some trains from Kokusai-tenjijo continue beyond Osaki toward Shibuya, Shinjuku, and Ikebukuro, while others do not. Read the destination before boarding rather than treating the morning pattern as a guarantee for the evening.
Routes from Tokyo Station, Ginza, and Shimbashi
One clear option from the Tokyo Station area is to travel to Shimbashi and take the Yurikamome to Tokyo Big Sight Station. Tokyo Station is large, so include walking time inside the station and time to find the correct Yurikamome entrance at Shimbashi.
Another rail option is to reach Shin-kiba by the JR Keiyo Line or Tokyo Metro Yurakucho Line, then transfer to the Rinkai Line for the short ride to Kokusai-tenjijo. This can make sense when your starting point already connects well to Shin-kiba.
From Ginza or another area with easy access to Shimbashi, the Yurikamome is easy to understand: board toward Toyosu and get off at Tokyo Big Sight Station. Check the official timetable and live service information before departure rather than relying on a saved weekday route, because C108 is held on a Saturday and Sunday.
Routes from Toyosu and Eastern Tokyo
From Toyosu, take the Yurikamome toward Shimbashi and get off at Tokyo Big Sight Station. The venue lists the ride from Toyosu as about nine minutes. From areas served by the Yurakucho Line, transferring at Toyosu can be more convenient than crossing central Tokyo to Shimbashi.
From Maihama and other JR Keiyo Line areas, travel to Shin-kiba and transfer to the Rinkai Line toward Osaki. Kokusai-tenjijo is about five minutes from Shin-kiba according to the venue. Keep the JR Keiyo Line platform location and transfer walking time in mind when estimating your full trip.
From Haneda Airport
Official Haneda Airport information lists airport buses for the Odaiba, Tokyo Big Sight, and Ariake area, with Tokyo Big Sight shown as roughly 20 to 40 minutes depending on the service and conditions. A direct bus can reduce transfers, but it is affected by the timetable, seat availability, stop pattern, and road traffic. Confirm the current operator schedule for your terminal before treating it as an option.
A rail alternative is to use the Tokyo Monorail to Tennozu Isle and transfer to the Rinkai Line toward Shin-kiba for Kokusai-tenjijo. Allow enough time to follow the transfer signs between the monorail and Rinkai Line stations. If you have large luggage, consider leaving it at your hotel or another appropriate storage location instead of building a crowded event trip around it.
Arriving at Haneda and attending C108 on the same day adds flight, baggage, immigration, transfer, and event-entry risks. Do not use the airport bus’s shortest listed time as a promise that you will reach a specific admission line on time.
From Narita Airport
Tokyo Big Sight’s English access page currently gives two different estimates for Narita Airport: its overview says about 60 minutes, while the detailed limousine bus section shows about 80 minutes to Ariake Park Building (Tokyo Bay Ariake Washington Hotel), followed by an approximately three-minute walk. Because bus routes and schedules can change, confirm the current operator’s stop and travel time before relying on this option. Road traffic and airport procedures can add substantial time.
For a rail trip, first choose an airport service that connects sensibly with your hotel or with a Tokyo transfer point, then use either the Rinkai Line or Yurikamome route described above. There is no single best Narita route for every terminal, hotel, ticket, and arrival time.
If C108 is a priority, staying in Tokyo before the event is more predictable than planning a same-day international arrival. This is practical advice, not an event rule.
Train Fares, IC Cards, and Station Names
Both the Rinkai Line and Yurikamome accept major nationwide transportation IC cards, including Suica and PASMO. Check the balance before joining an event-day crowd. A route that crosses JR and the Rinkai Line can include fares from more than one operator even when one IC card handles the gates.
Yurikamome ticket machines have an English option. The line also supports compatible contactless payment cards and devices at its stations, but this is separate from a transportation IC card. Use the same payment method at entry and exit, and do not assume that a foreign card will work until you have confirmed it is supported.
Remember the two names: Kokusai-tenjijo for the Rinkai Line and Tokyo Big Sight for the Yurikamome. Save the line name with the station name so you do not search for the correct name on the wrong network.
Plan the Return Before You Arrive
Do not wait until you are tired and standing in a crowd to invent the trip home. Save a primary route and a backup route before C108. A simple pair is Kokusai-tenjijo by the Rinkai Line and Tokyo Big Sight by the Yurikamome, but the useful endpoints depend on your hotel.
Check live service information before walking to a station. If one line is suspended, follow official railway and event staff guidance; do not assume the other station is immediately available through the usual walking route. Crowd controls and temporary directions may change how people leave the venue.
Allow more time than an ordinary route search suggests if you have a Shinkansen, flight, restaurant booking, or other fixed reservation. Published line times do not include the wait to enter a station, a missed connection, or slow movement through a large transfer station.
Accessibility and Step-Free Planning
Tokyo Big Sight publishes access maps showing routes from nearby stations, as well as separate accessibility information. Check both before the event if you need elevators, step-free movement, or a route suitable for a wheelchair. Railway station pages can also help you identify station facilities before travel.
C108 waiting lines and crowd-control routes may differ from the venue’s normal access path. At the venue, follow the current signs and ask staff for the appropriate route instead of assuming that the shortest ordinary path is open.
A Simple Access Plan
- Confirm your C108 admission type and any station-specific exchange instruction.
- Choose Kokusai-tenjijo on the Rinkai Line or Tokyo Big Sight on the Yurikamome based on your starting area.
- Save the exact transfer stations and train directions, not only the destination name.
- Prepare a return route using the other line when it is practical for your hotel.
- Check the Saturday or Sunday timetable, live service status, and C108 information map before leaving.
- At the venue, follow current staff directions when they differ from your saved route.
Common Access Mistakes
- Searching for Tokyo Big Sight Station on the Rinkai Line instead of Kokusai-tenjijo.
- Assuming every Saikyo Line train continues onto the Rinkai Line.
- Counting only the train ride and forgetting transfer and station walking time.
- Using a weekday screenshot for a weekend event without checking the current timetable.
- Choosing an airport bus without confirming the departure terminal, current schedule, and exact stop.
- Planning only one route for both arrival and departure.
- Treating the shortest published time as a guaranteed event-day arrival time.
