Unlocking Tokyo’s Best-Kept Winter Secret for Gamers
If you are planning an inbound trip to Japan during the late December holiday season, your itinerary is likely already packed with winter illuminations, New Year’s shrine visit preparations, and massive shopping expeditions. But if you are a fan of video games, esports, or internet culture, there is an absolute hidden gem happening right in the heart of Tokyo that most international tourists have no idea they can attend.
Welcome to RTA in Japan Winter 2026 (日本語: RTA in Japan Winter 2026).
Held continuously over a staggering week-long period from December 25 (Friday) through December 31 (Thursday), 2026, this event is a massive, non-stop, 24-hours-a-day speedrunning charity marathon. Organized by the general incorporated association (一般社団法人) RTA in Japan, it gathers top-tier Japanese and international gamers to shatter world records and complete video games as incredibly fast as possible live on stage.
For the international traveler, the most astonishing part of this world-class gaming event is its accessibility: no advance reservations or applications are required to enter, and visitors can walk in freely off the streets of Tokyo. Furthermore, based on the official event and admission pages, no entrance fee is mentioned anywhere for this edition—consistent with how this deeply community-driven event has operated in the past.
Whether you are battling jet lag and need something exhilarating to do at 3:00 AM, or you want to take a midday break from sightseeing to watch masters manipulate code in real-time, RTA in Japan Winter 2026 offers an incredibly rare, welcoming environment. This exhaustive guide will cover everything you need to know to simply walk in and watch, from navigating the confusing venue name to understanding the rules, exploring the game lineup, and finding the best nearby spots to eat and shop for retro games.
What is RTA? Understanding the Japanese Speedrunning Scene
For those who might be casual gamers, the term "RTA" might be unfamiliar. In the Western gaming community, the practice of beating a video game as fast as possible is generally called "speedrunning," popularized by massive biannual charity events like Games Done Quick (GDQ).
In Japan, this exact same practice is referred to as RTA, which stands for Real Time Attack. The terminology differs, but the spirit is entirely the same. Players spend thousands of hours studying a game's programming, mastering pixel-perfect movements, and discovering reality-bending glitches to skip massive portions of a game, all while a live audience cheers them on.
The Scale of RTA in Japan
RTA in Japan is not a small, underground gathering—it is a cultural phenomenon within the Japanese gaming sphere. The official RTA in Japan YouTube channel boasts an audience of over 400,000 subscribers, making it a globally recognizable hub for speedrun fans. During the marathon, tens of thousands of viewers tune in concurrently online to watch runners break games ranging from the latest triple-A RPGs to bizarre, obscure retro titles.
Despite this massive digital footprint, the in-person event retains a surprisingly relaxed, community-first atmosphere. It is primarily an "offline" (in-person) event held at a physical venue in Tokyo, though it does feature some online/remote participation for runners who cannot make the trip.
Gaming for a Cause
Speedrunning marathons are intrinsically linked to charitable giving, and RTA in Japan is no exception. The event is run as a dedicated charity marathon. After operational costs and taxes are accounted for, the proceeds raised during the event are donated to Doctors Without Borders (Médecins Sans Frontières / 国境なき医師団).
By attending, buying merchandise (if available on-site), or tuning into the stream, attendees are directly supporting vital global medical and humanitarian efforts. The event is made possible through the cooperation of key sponsors listed on the official page, including gaming apparel brand 無敵時間 (Muteki Jikan) and real estate/venue operator 住友不動産ベルサール (Sumitomo Fudosan Belle Salle).
Why This is the Ultimate Tourist-Friendly Event
If you are an international tourist visiting Japan in winter 2026, here is why RTA in Japan should immediately go on your itinerary.
1. No Advance Tickets Required
One of the most frustrating aspects of Japanese pop culture events—from anime pop-up cafes to specialized museums—is the strict requirement for advance ticketing, lottery systems, and domestic Japanese phone numbers. RTA in Japan Winter 2026 bypasses all of this. The official admission page explicitly states that visitors "may enter freely without advance application." While you should always double-check the official site immediately before your visit in case policies update, the standard protocol is simply walking through the front door.
2. The 24-Hour Schedule is a Jet-Lag Cure
Doors open at 14:00 on Friday, December 25, 2026. From that moment onward, the marathon runs entirely non-stop, 24 hours a day, through December 31. Once the doors open, visitors are free to enter and exit at any time of the day or night. If you wake up at 4:00 AM due to jet lag and the trains haven't started running yet, you can grab a taxi to the venue and watch someone blast through a retro classic while the rest of the city sleeps.
3. The Universal Language of Gaming
While the on-stage commentary, event signage, and staff interactions will almost exclusively be in Japanese, speedrunning is a visual, universal language. You do not need to speak a word of Japanese to understand the sheer hype of a runner successfully executing a frame-perfect glitch to skip a final boss. The communal gasps, the claps, and the on-screen action transcend linguistic barriers.
To help make your broader trip smoother regarding payments and communication, you can read our guide on Cash vs Card in Japan 2026: How Much Cash Do You Need?. Speaking of cash, since no international payment support or English-speaking staff guarantees are listed on the official pages, you should absolutely come prepared with physical Japanese Yen and a translation app on your phone just in case you need to communicate with staff or buy something.
The Games of Winter 2026: What to Expect Live on Stage
On October 18, 2026, the organizers announced the selected games for the Winter edition. According to event coverage from Game*Spark via Yahoo! News, approximately 90 video games were chosen to be played live on stage.
Important Note on Scheduling: The detailed, game-by-game timetable with specific times and days was slated to be announced on October 25, 2026. If you are reading this prior to that date, exact times are not yet available. If you are reading this after October 25, be sure to check the official RTA in Japan schedule page or their official X (Twitter) account to see exactly when your favorite games will be run so you can plan your walk-in visit accordingly.
While the full 90-game list is massive, here is a sampling of the incredible titles, franchises, and bizarre challenge runs confirmed for this event:
Modern Masterpieces and Heavy Hitters
The 2026 Winter lineup features some absolute titans of the modern gaming landscape.
- Hollow Knight: Silksong: The highly anticipated sequel to the indie metroidvania masterpiece will be run here, promising mind-bending movement mechanics and incredibly fast combat.
- FINAL FANTASY XVI: Square Enix's action-heavy RPG epic will be dismantled live on stage, likely showcasing incredible combat optimization.
- SILENT HILL f: The newest psychological horror entry will see runners speeding through its terrifying environments, prioritizing speed over scares.
- Civilization VII: Speedrunning a deep, turn-based historical strategy game is always a fascinating watch, relying heavily on deep mechanical knowledge and rapid menu navigation.
The Return of Nintendo
According to background reporting by Game*Spark, Nintendo titles were notably absent from the Summer 2025 edition of RTA in Japan. However, they have returned in full force for Winter 2026, providing a nostalgic treat for attendees.
- The Legend of Zelda: Skyward Sword & The Legend of Zelda: Twilight Princess HD: Expect massive dungeon skips, sequence breaks, and masterclass controller inputs.
- Pokémon Sword: A masterclass in route planning, menu optimization, and manipulating RNG (random number generation) to blaze through the Galar region.
- Metroid Prime Remastered: The classic speedrun franchise returns in high definition, featuring out-of-bounds tricks and flawless platforming.
Retro Classics and RPGs
Speedrun marathons are where retro games truly shine, and the Winter 2026 lineup is packed with nostalgia.
- Doom 64: Lightning-fast FPS action on a retro console.
- Clock Tower 2: Classic point-and-click horror where runners manipulate the AI of the pursuers to save precious seconds.
- Castlevania: Circle of the Moon ("奪われた刻印" release): Expect classic Metroidvania sequence breaking and boss melting.
- Mega Man Battle Network 4: A fascinating hybrid of real-time action and deck-building card mechanics optimized for speed.
- Ys VI and Shadowgate will also be featured, alongside the classic RPG Dengeki Maō ZERO (天外魔境ZERO).
- FINAL FANTASY TACTICS – The Ivalice Chronicles: A deep dive into strategy RPG speedrunning.
Novelty, Challenge, and Race Categories
Some of the most crowd-pleasing moments at RTA in Japan come from custom categories, artificial handicaps, or head-to-head races.
- Super Mario 64 (Blindfolded Run): A runner will attempt to beat the foundational 3D platformer using only audio cues and muscle memory, entirely blindfolded. This is always a show-stopping event.
- Donkey Kong 64 "0.0% (Low%)" Run: In a game infamous for requiring the player to collect thousands of colored bananas, coins, and blueprints, this runner will exploit glitches to finish the game collecting literally as close to nothing as the game's code will allow.
- Resident Evil Village "VR Mode NG Glitchless": Beating a terrifying horror game as fast as possible is hard enough, but doing it in virtual reality without relying on game-breaking glitches requires immense physical coordination and nerves of steel.
- The Legend of Zelda (1986) "Swordless First Quest": Completing the original NES classic without ever picking up the wooden sword from the old man in the cave.
- Animal Crossing "Credits" Category: Speedrunning a real-time life simulator to see the ending credits as fast as humanly possible.
- Time Crisis 2 Single-Controller Run: A fascinating arcade feat.
- Races: Expect high-energy, multi-runner versus formats and races for titles including Donkey Kong Bananza, New Super Mario Bros. Wii (4-player race), Resident Evil Gaiden, and the delightfully bizarre わびさび寿司ダービー (Wabi-Sabi Sushi Derby).
Essential Venue Details (CRITICAL: DO NOT GO TO THE WRONG BUILDING)
If there is one single piece of advice you take away from this guide, let it be this: Double-check your Google Maps destination carefully.
The event is held in the Bunkyo ward of Tokyo, near Iidabashi Station. However, there are two venues in this area with nearly identical names, and the official admission page explicitly warns attendees not to confuse them.
- THE CORRECT VENUE: ベルサール飯田橋ファースト (Belle Salle Iidabashi First)
- THE WRONG VENUE: ベルサール飯田橋駅前 (Belle Salle Iidabashi Ekimae)
Make absolutely sure you route yourself to Belle Salle Iidabashi First.
Venue Location & Map
Venue Name: Belle Salle Iidabashi First (ベルサール飯田橋ファースト) Address: 住友不動産飯田橋ファーストタワー B1F, 2-6-1 Koraku, Bunkyo-ku, Tokyo (東京都文京区後楽2丁目6-1 住友不動産飯田橋ファーストタワーB1F)
How to Get There
The venue is incredibly easy to access from central Tokyo. It is walking distance from Iidabashi Station, which is serviced by a massive number of train and subway lines:
- JR Chuo-Sobu Line
- Tokyo Metro Tozai Line
- Tokyo Metro Yurakucho Line
- Tokyo Metro Namboku Line
- Toei Oedo Line
From the station exits, it is roughly a 5 to 8-minute walk to the Sumitomo Fudosan Iidabashi First Tower. The venue is located on the B1F (Basement 1) level. If you are navigating Tokyo's complex subway system, we highly recommend reading our guide on What is the Best IC Card for Tourists in Japan 2026? | Suica vs Pasmo vs ICOCA to ensure smooth tap-and-go transit.
The Rulebook: How to Attend Like a Local
Because RTA in Japan Winter 2026 is a free, unreserved community event, it relies heavily on the good behavior and cooperation of its attendees. To ensure you don't accidentally commit a faux pas or get turned away, you must strictly follow the organizer's guidelines, which we have verified directly from the official admission page.
1. Crowding and Entry Restrictions
While admission is free and open, the venue has a physical capacity limit. The official site notes that admission may be temporarily restricted during periods of high crowding.
- Crucial Rule: If a restriction is put in place, you are strictly asked not to wait in line inside the building or around the venue grounds. Loitering outside causes issues for the building management.
- How to Check: Any crowd restrictions, pauses on entry, or reopening announcements will be posted immediately to the official X (Twitter) account @RTAinJapan and their Bluesky account rtainjapan.bsky.social. Check these accounts before you leave your hotel.
2. Age Restrictions (Important for Families)
If you are traveling with teenagers or small children, you must be aware of Tokyo's local ordinances regarding minors at late-night events, which the organizers strictly enforce:
- Under 18 years old: May not enter the venue after 22:00.
- Under 16 years old: May not enter the venue after 18:00 on their own. However, if accompanied by a parent or guardian, they may stay until 22:00.
- Preschool-age children: Must be accompanied by a guardian at all times while inside the venue, regardless of the hour.
3. Food, Drink, and Trash Policy
- Drinks: You are allowed to bring drinks into the venue, but they must be in a spill-proof, lidded container (like a plastic PET bottle or a thermos). Open cups (like standard cafe takeout cups without a seal) are risky around expensive gaming and streaming equipment.
- Food: Eating is strictly prohibited inside the venue. Do not bring bentos, snacks, or convenience store food to eat in the viewing area. (We have provided a list of great nearby restaurants further down in this guide).
- Alcohol: Bringing alcohol into the venue, or arriving under the influence of alcohol, is strictly prohibited.
- Trash: There are no communal trash cans provided for attendees. You must take all of your own trash with you when you leave.
4. Belongings and Security
There is no coat check, locker system, or bag storage service available at the venue. You are entirely responsible for your own belongings, and the organizers explicitly state they are not liable for any theft or loss. Keep your bags close, and if you are carrying massive amounts of anime merchandise from a day of shopping in Akihabara, consider dropping it off at your hotel before heading to Iidabashi.
5. Health, Illness, and COVID Precautions
While strict pandemic-era rules have largely receded, the event maintains common-sense health guidelines, especially since it takes place during peak winter flu season:
- Hand sanitizing at entry and mask-wearing inside the venue are currently optional.
- Caveat: The organizers reserve the right to request masks or sanitizing depending on flu, COVID, or other infectious disease trends at the time of the event. (The official page even notes the format could theoretically be scaled down or moved online if disease conditions become severe, though this is a low-probability worst-case scenario. Expect an in-person event, but bring a mask just in case).
- Visitors displaying a fever or visible symptoms of severe illness may be denied entry or asked to leave to protect the runners and other attendees.
6. Photography, Video, and Streaming Rules
- The Official Stream: By entering the venue, you consent to the fact that you may appear on camera in the event's official livestream or archived recordings.
- Personal Photography: You are allowed to take personal photos inside the venue. However, you are strongly asked to be mindful of other attendees' privacy and likeness rights before posting any photos of the crowd to social media. Try to focus your camera on the stage, the screens, or willing friends.
- No Unauthorized Streaming: Personal livestreaming from inside the venue without explicit prior permission from the organizers is strictly prohibited. Do not walk around the hall IRL-streaming to your own Twitch or YouTube channel.
7. Accessibility Accommodations
The event strives to be accessible. If you are a visitor using a wheelchair or require the use of a stroller, you are asked to contact the organizers in advance so they can ensure a smooth experience. You can reach them via email at info@rtain.jp or by reaching out to the administrative team on the official RTA in Japan Discord server.
Surviving a 24-Hour Marathon: Where to Eat and Drink Nearby

Expanding Your Trip: Gaming Tourism Near Iidabashi
Watching world-class speedrunners destroy your favorite retro games live on stage is likely to give you an intense itch to actually play those games yourself. Fortunately, the location of RTA in Japan Winter 2026 is an absolute blessing for inbound gaming tourists.

Here are a few specific, highly recommended spots in Akihabara to pair with your RTA in Japan itinerary:
1. Super Potato Akihabara Branch
The most famous retro game store in Japan. While prices here carry a "tourist tax" premium compared to stores out in the deep suburbs (like Hachioji), the sheer volume of perfectly preserved Famicom, Super Famicom, N64, and Game Boy games is a museum-like experience. Even if you don't buy anything, climbing the narrow stairs to browse the aisles of pristine boxed classics is a rite of passage.

For broader hotel advice across the geek-centric eastern side of Tokyo, take a look at our Best Hotels Near Akihabara 2026 | Value Location Convenience rundown. But if you want to be within walking distance of the Belle Salle Iidabashi First venue, consider these options:
1. Hotel Metropolitan Edmont Tokyo
This is arguably the most convenient hotel for the event. It is a highly-rated, comfortable western-style hotel situated almost immediately next to the event venue in Iidabashi.

Final Trip Preparation Checklist
Before you pack your bags for a snowy Tokyo winter and prepare to watch the world’s fastest gamers, keep these final tips in mind:
- Check the Schedule (After Oct 25, 2026): Because the detailed per-game timetable isn't finalized until late October, wait until closer to your trip to pinpoint exactly when the Metroid Prime Remastered run or the blindfolded Super Mario 64 run is happening. Match those times against your tourism itinerary.
- Bookmark the Socials: Follow @RTAinJapan on X (Twitter) or rtainjapan.bsky.social on Bluesky. If the venue hits capacity, this is where you will find out. Do not waste a subway trip if they have announced a temporary freeze on entry.
- Prepare for the Livestream: While the official Winter 2026 page does not explicitly restate it for this exact edition, based on how every past edition of this event has operated, it is very likely that the entire marathon will be live-streamed. The official site prominently links to its Twitch channel (twitch.tv/rtainjapan) and notes that past event recordings are archived there and on YouTube. If you are stuck in your hotel room during a snow flurry, boot up the stream and watch from bed.
- Bring Cash: With no entrance fee mentioned but the potential for charity donations or merchandise, ensure you have Japanese Yen.
- Be Respectful: Remember, this is a charity event supporting Doctors Without Borders (Médecins Sans Frontières). Take your trash home, don't stream on your phone inside, and cheer loudly (or politely clap, as is often the Japanese custom) when a runner lands a difficult glitch.
RTA in Japan Winter 2026 is exactly the kind of serendipitous, deeply subcultural experience that makes traveling to Tokyo so magical. It strips away the reservation lotteries and high entrance fees of modern pop-up events, replacing them with raw passion, mind-bending video game exploits, and a welcoming community that operates around the clock. Whether you stay for 20 minutes or 12 hours, stepping into Belle Salle Iidabashi First this December will guarantee you a Tokyo winter memory unlike any other.
