If you are an international traveler who has marveled at the immersive digital art revolutions that have swept through Japan over the last decade, it is time to update your itinerary. On Wednesday, October 14, 2026, the landscape of Japanese digital art shifts once again with the grand opening of null²ⁿ (stylized and read as Null-Null Nexus / ヌルヌルネクサス in Japanese).
Located inside the iconic Yokohama Landmark Plaza, this brand-new, permanent immersive digital-art venue is the brainchild of internationally recognized media artist and University of Tsukuba professor Yoichi Ochiai (落合陽一). Billed by its official site as a "permanent museum theater," null²ⁿ is poised to become one of the absolute must-visit cultural attractions in the Greater Tokyo Area.
Whether you are a die-hard fan of tech-art installations or a casual tourist looking to experience the bleeding edge of Japanese interactive media, visiting a new, high-demand attraction in Japan requires meticulous planning. This massive, exhaustive guide covers absolutely everything you need to know before you go: the origin story of the exhibit, a room-by-room preview, a deep dive into the complex ticketing system, strict venue rules, and how to seamlessly integrate this futuristic journey into your Yokohama day trip.
1. The Origin Story: Reborn from the Osaka Expo
To truly appreciate the scale and significance of null²ⁿ, you have to understand its origins. The narrative driving this new Yokohama venue is one of overwhelming demand and a second chance for millions of art enthusiasts.
The Phenomenon of the "null²" Pavilion
During Expo 2025 Osaka-Kansai, Yoichi Ochiai served as a theme producer and created a highly acclaimed pavilion named "null²". According to the historical context provided on the new venue's official website, Expo 2025 drew roughly 25.5 million total visitors. However, because of immense popularity and venue capacity limits, only about 540,000 visitors were actually able to get inside Ochiai's pavilion.
If you do the math, that means only about 2% of all Expo visitors were lucky enough to experience the installation. The remaining 98%—over 25 million people—went home having missed out on one of the Expo's most talked-about digital marvels.
A Permanent Venue for the 25 Million
The official site frames the creation of Yokohama's null²ⁿ explicitly around this massive unmet demand. In a statement attributed to Ochiai on the official website, null²ⁿ is positioned as a successor—a "reborn" version of the original Expo pavilion, constructed "one year later" specifically for the 25 million people who could not get into the Osaka installation.
Unlike the temporary Expo pavilion, null²ⁿ is a permanent venue. The official site explicitly states that "there is no closing date, and you can book... you're allowed to come back again" (会期はなく, meaning there is no fixed exhibition period). This transition from a fleeting world's fair pop-up to a permanent fixture in Yokohama means that international tourists can confidently add this to their long-term bucket lists.
(Note: While null²ⁿ is framed as a successor to Ochiai's Expo pavilion, the official site presents this as the artist's own independent continuation project. It is not officially operated by the Japan Association for the 2025 World Exposition.)
2. Who is Yoichi Ochiai?
For international visitors who might be more familiar with collectives like teamLab, the name Yoichi Ochiai might be new, but he is a titan in the Japanese tech and art spheres.
Ochiai is a media artist, academic, and researcher who holds a prominent position as a professor at the University of Tsukuba. He is internationally recognized for his work bridging the gap between analog reality and digital computation. His artistic philosophy often revolves around what he terms "Digital Nature"—the idea that as computing becomes ubiquitous, the boundary between the artificial and the natural dissolves, creating a new integrated ecosystem.
By visiting null²ⁿ, you are not just walking into a room with pretty lights; you are stepping into a profound philosophical thesis crafted by one of Japan's most forward-thinking modern intellectuals.
3. The Concept: "The Radiance of Life Within Computational Nature"
Before we break down the physical rooms, it is crucial to understand what you are actually looking at. The official concept of null²ⁿ is described on the site as "The Radiance of Life Within Computational Nature."
The venue is built around a concept called the "Mirrored Body." When visitors enter the space, their physical bodies are essentially digitized. This digitized version of yourself then interacts with other purely digital bodies and entities generated within the venue's systems. The official site boldly describes this convergence of human and machine data as "an interactive structure humanity has never witnessed."
For travelers who love immersive art, this promises a highly personalized, reactive experience where your physical presence actively alters the digital environment around you.
4. The null²ⁿ Experience: A Room-by-Room Walkthrough
The venue is intricately structured to guide visitors through a specific emotional and sensory narrative. The average total visit time is estimated at about 60 minutes, though individual paces may vary.
The experience comprises five designated "experience areas" plus a central "permanent museum theater." The entire venue is built around two massive, state-of-the-art large LED displays.
Visitors will pass through six named rooms in a strict sequential order. Here is what you can expect in each zone:
00 Gate (門, "Tremble")
Your journey begins at the Gate. Subtitled "Tremble," this initial threshold serves to separate you from the bustling, mundane reality of the Yokohama Landmark Plaza shopping mall. It sets the sensory baseline, preparing your eyes and ears for the digital wilderness ahead.
01 First Room (壱の間, "Bewilder" / "Goodbye, Homo sapiens")
Stepping into the First Room, you encounter a space themed around the concept of "Goodbye, Homo sapiens." This provocative title suggests a departure from traditional human perception. Expect to feel intentionally disoriented—or "bewildered"—as the digital environment begins to analyze and digitize your presence.
02 Second Room (弐の間, "Attune" / "Dream of the Null Eye Realm")
CRITICAL WARNING: This room requires complete compliance with strict rules. The Second Room, subtitled "Dream of the Null Eye Realm," is an exercise in sensory deprivation and deep focus.
- The Environment: It is in complete darkness.
- The Posture: It is experienced entirely seated.
- The Strict Rule: There is NO photography or video recording allowed here whatsoever. (More on photography rules later). This room is designed to "attune" your senses. By removing the urge to capture content for social media and plunging you into darkness, the artist forces you to be intensely present in the moment.
03 Third Room (参の間, "Wonder" / "Longing for Mass")
Emerging from the darkness of the Second Room, you enter the Third Room, subtitled "Longing for Mass." Unlike the seated restriction of the previous space, this is a large gallery where visitors are encouraged to walk around freely. Fascinatingly, this room features an exhibition of historical hardware and physical inventions. It serves as a stark, tangible contrast to the intangible digital projections you will see elsewhere, prompting "wonder" about the physical mass and history of computing that makes digital art possible.
04 Fourth Room (肆の間, "Fly" / "Dream of the Latent Space")
The narrative accelerates in the Fourth Room. Subtitled "Dream of the Latent Space," this area leans heavily into the realm of artificial intelligence and generative digital creation (the "latent space" being a term heavily used in machine learning). The theme here is "Fly," suggesting a soaring, expansive visual and auditory experience as your "Mirrored Body" interacts with the digital ether.
05 Bridge (橋, "Return" / "The Far Shore of Signs")
The final stage of your 60-minute journey is the Bridge. Subtitled "The Far Shore of Signs," this transition space represents the "Return" to reality. It allows visitors to decompress, process the intense sensory input of the computational nature they just inhabited, and prepare to step back out into the physical world of Yokohama.
5. Location and Access: Navigating to Yokohama Landmark Plaza
null²ⁿ is located in the heart of Yokohama's iconic Minato Mirai 21 district.
Official Address: Landmark Plaza 5F, Yokohama Landmark Tower 2-2-1 Minatomirai, Nishi-ku, Yokohama, Kanagawa 220-8172
Google Maps Location
How to Get There (Access Guide)
Yokohama is highly accessible from central Tokyo, making this a perfect day trip. The official site notes approximate walking times from the two closest major stations:
- From Minatomirai Station (Minatomirai Line): Approx. 3 minutes on foot.
- Travel Tip: The Minatomirai Line connects seamlessly to the Tokyu Toyoko Line. If you are staying in Shibuya, you can take a direct Express or Limited Express train that runs straight through to Minatomirai Station without needing to transfer.
- From Sakuragicho Station (JR Negishi Line / Yokohama Municipal Subway Blue Line): Approx. 5 minutes on foot.
- Travel Tip: Sakuragicho is easily accessible via the JR Keihin-Tohoku Line (which merges into the Negishi Line) from major Tokyo hubs like Tokyo Station, Yurakucho, and Shinagawa. To ride the JR lines efficiently, you will want a transit smart card. If you are unsure which one to get, check out our guide: What is the Best IC Card for Tourists in Japan 2026? | Suica vs Pasmo vs ICOCA. The walk from Sakuragicho to the Landmark Tower features moving walkways, making it very comfortable even in summer heat.
(Note: The venue is on the 5th Floor of the Landmark Plaza mall, which is the sprawling shopping center situated at the base of the towering Yokohama Landmark Tower).
6. Opening Hours and Time Slots
null²ⁿ operates on a strict, time-slotted reservation system to control crowd flow and preserve the integrity of the art.
- Planned Operating Hours: 9:30 – 21:00
- First Entry Slot: 9:30 "meeting slot"
- Last Entry Slot: 19:40 "meeting slot"
- Closing Time: 21:00
Important Note from the Official Site: These hours are listed as "planned," and any temporary changes, maintenance closures, or adjusted holiday hours will be announced on the official website. Always double-check the site before boarding the train to Yokohama.
Understanding "Meeting Slots" in Japan
In Japanese ticketing terminology, a "meeting slot" (集合時間) usually means the specific window during which you are allowed to line up for entry. It does not necessarily mean you will step through the "00 Gate" exactly at that minute. You must arrive at the 5th-floor venue during your designated meeting slot. If you book the 19:40 slot, do not be late, as it is the final entry of the night.
7. Ticket Prices and Types (Tax Included)
Advance reservation with a fully specified date AND time is required. By default, this is not a walk-in attraction. You must secure your digital tickets online beforehand.
Standard Tickets
| Visitor Category | Weekday Price | Sat / Sun / Holiday Price |

| Adult (Age 13+) | ¥3,900 | ¥4,500 |
| Child (Age 4–12) | ¥3,000 | ¥4,000 |
Original Pin Badge Tickets (Limited Quantity)
For collectors and super-fans, the venue offers a premium ticket tier that includes an exclusive original pin badge. These are strictly while stock lasts.
| Visitor Category | Weekday Price | Sat / Sun / Holiday Price |

Make sure your phone is charged! (If you need a power bank delivered to your hotel before you travel, read: How to Order From Amazon Japan Before Your Trip and Ship It to Your Hotel).
8. CAUTION: The December 2026 Caveat (READ BEFORE PLANNING)
Because null²ⁿ is heavily anticipated, you might be tempted to start booking flights for Christmas 2026 or early 2027 right now. Stop and read this carefully.
As of our primary fact-check date (October 15, 2026), the official FAQ explicitly states that whether reservations will open for December 2026 onward is "currently undecided."
Do NOT plan a trip to Japan around a specific December or 2027 visit date assuming the booking calendar will automatically open. As a permanent venue, it will remain open, but their ticketing schedule release cycle for the winter months has not been finalized. We strongly advise monitoring the official site (https://null2.nexus/) for updates on the bookable date range before finalizing your Yokohama itinerary.
9. Ticket Changes, Cancellations, and Refunds
Japan's digital ticketing landscape is notoriously strict regarding refunds, and null²ⁿ is no exception. Understanding these rules is paramount for international travelers whose itineraries might change due to jet lag, train delays, or weather.
The No-Refund Policy
Cancellations and refunds for customer-side reasons are NOT accepted under any circumstances. This includes:
- Mistaken purchases (buying the wrong date or wrong quantity).
- Sudden illness or fatigue.
- Transportation trouble (missing your train, getting lost in Yokohama Station).
- Traffic delays.
If you buy a ticket and cannot make it, you lose your money. Period.
Changing Your Date/Time (Official Site Purchases Only)
While refunds are banned, the venue does offer a generous change policy, provided you bought your ticket directly on the official null²ⁿ website (and not through a third party).
- You can change the date and time of your visit an unlimited number of times via your "My Page."
- Deadline for changes: You must make the change by 23:59 (11:59 PM JST) on the day before your reserved date. You cannot change a same-day ticket.
- Changing Ticket Tiers: If you change a Weekday ticket to a Weekend/Holiday ticket, you will be required to pay the price difference. If you change a Weekend/Holiday ticket to a Weekday ticket, you will be refunded the price difference.
- Change Limits: You are limited to 5 such "price-difference-changes" per order per 24-hour period.
- What Cannot Be Changed: You cannot change the ticket type (e.g., swapping an Adult ticket for a Child ticket), you cannot change the quantity of tickets, and you cannot add or remove the "goods option" (Pin Badge) after the initial purchase.
Third-Party Partner Tickets
The official site notes that tickets are also sold through select partners:
- JTB: Offering a special travel-plan bundle that includes a JTB-only entry slot, a special presentation, and original goods (Note: The official site describes this JTB page as Japanese-language only).
- Rakuten Travel Experiences: Where users can earn or spend Rakuten Points (also described as Japanese-language only).
Important: If you purchase through JTB or Rakuten Travel Experiences, you cannot use the official site's "My Page" to change your tickets. All changes, inquiries, or modifications for partner-bought tickets must be handled directly through that specific partner agency.
10. Can I Buy Same-Day Tickets?
Yes, but only conditionally.
Same-day tickets are only sold if a specific time slot still has availability. If the venue is sold out online, there will be no same-day tickets available.
If there is space, same-day tickets can be purchased in two ways:
- Via the official website.
- At an on-site ticket counter on the 5th floor.
Warnings for the On-Site Counter:
- Counter prices may differ from the online advance prices.
- Tickets are sold strictly while stock lasts for that day.
- Payment is 100% Cashless. Cash is not accepted at the venue counter under any circumstances. You must use a credit card or approved digital payment. If you are unsure about how cashless payments work for tourists in Japan, read our guide: Cash vs Card in Japan 2026: How Much Cash Do You Need?.
11. Ticket Transfers and Sharing with Companions
Because tickets are tied to a QR code on the purchaser's smartphone, navigating entry with a group requires attention.
- Resale is Strictly Prohibited: You cannot change the named holder of the ticket, and reselling tickets for profit is strictly banned.
- Sharing with Companions: If you bought 4 tickets for your family, you do not all have to enter at the exact same second if someone needs to use the restroom. The purchaser can share the ticket's QR code/URL with a companion who is joining them. This is done via a dedicated "Share This Ticket" feature located on the ticket page. Your companion can then load their individual QR code on their own smartphone to pass through the 00 Gate.
12. Venue Rules: Photography, Food, and Medical Warnings
To protect the art and ensure the safety of all visitors, null²ⁿ enforces a strict set of visitor guidelines. Read these carefully so you aren't turned away at the door.
Photography and Social Media
We know you want to post this to Instagram and TikTok. Generally, photography and recording are allowed inside the venue, and posting to social media is permitted. However, there are massive exceptions:
- No Flash Photography: This ruins the projections and blinds other guests.
- No Tripods or Monopods: They are a tripping hazard in the dark.
- No Selfie Sticks: You cannot swing metal poles around in a crowded, mirrored room.
- THE SECOND ROOM BAN: As mentioned in the walkthrough, the 02 Second Room ("Dream of the Null Eye Realm") is a dark, seated experience. Absolutely no photos or video are allowed in this room.
- Staff Guidance: Always follow on-site staff instructions, as specific temporary shooting restrictions may apply to certain areas.
The Strict Food and Drink Ban
There are no restaurants, cafes, or vending machines inside null²ⁿ. Furthermore, bringing any food or drink inside is strictly prohibited.
- This explicitly includes bottled water, chewing gum, and candy.
- Why? The venue relies heavily on pristine mirrored floors, sensitive LED panels, and delicate interactive technology. A spilled bottle of water or dropped gum could cause thousands of dollars in damage or ruin the experience for everyone else.
- Advice: You must finish all food and drink before you enter the queue. If you are thirsty, buy a drink from a vending machine in Landmark Plaza and finish it before heading to the 5th floor. (Curious about drinking water in Japan? Check out: Can You Drink Tap Water in Japan? | City by City Guide 2026).
Medical and Sensory Warnings
While the official site explicitly states that null²ⁿ is NOT a horror or haunted-house attraction and contains absolutely no effects intended to deliberately startle or scare visitors, it is an intense sensory environment.
The site provides explicit warnings for the following demographics:
- People with a history of photosensitive seizures (epilepsy).
- Anyone who may feel unwell from flashing lights, strobe-like LEDs, or intense projection mapping.
- Those sensitive to loud sound effects or booming audio.
- People who experience anxiety or illness in dark, enclosed spaces.
- People with weak hearts.
- Anyone using a medical device such as a pacemaker.
If you fall into any of these categories, the site advises that you should refrain from visiting or take sufficient care. The combination of intense strobe lighting, booming bass, and pitch-black rooms (especially the Second Room) is core to the art piece.
Accessibility Guidelines
- Wheelchairs: Wheelchair entry into the venue is possible. However, the venue notes that there are some steps, mirrored floors, and very dark areas, so navigation will require care.
- Strollers: Baby strollers may be declined entry for safety reasons due to the dark environments and crowds. Plan to leave strollers at a designated mall facility or your hotel.
13. Comparing null²ⁿ to Other Japan Digital Art Experiences
For inbound tourists, Japan is famous for immersive digital art, most notably the mega-museums operated by teamLab (like teamLab Planets in Tokyo). So, how does Yoichi Ochiai's null²ⁿ compare?
While both utilize large-scale projections, mirrors, and interactive light, their core philosophies differ wildly.
- teamLab often focuses on organic motifs (flowers, water, animals) and a romanticized connection with traditional nature, creating a highly playful, barefoot, wading-through-water experience.
- null²ⁿ is heavily rooted in academia, computational theory, and the digital frontier. The inclusion of the "Third Room" featuring historical hardware and physical computing inventions sets it apart as a space that reflects deeply on the technology itself. The themes of "Goodbye, Homo sapiens" and the "Mirrored Body" offer a more cyberpunk, transhumanist, and intensely philosophical atmosphere.
If teamLab is a digital garden, null²ⁿ is a digital nervous system. If you love one, you will absolutely want to experience the other to see the two prevailing schools of modern Japanese digital art.
14. Planning Your Yokohama Day Trip Around null²ⁿ
Because null²ⁿ takes roughly 60 minutes, it is the perfect anchor for a full day out in Yokohama. The Minato Mirai area is arguably one of the most tourist-friendly and visually stunning port districts in Japan.
Pre-Exhibition: Shopping and Dining in Landmark Plaza
Since you cannot bring food or water into the venue, take advantage of the massive Landmark Plaza shopping mall beforehand. There are dozens of restaurants on the lower floors offering everything from quick udon to high-end sushi.
Post-Exhibition: Nearby Attractions
After your mind is blown by the "Radiance of Life Within Computational Nature," step out of the Landmark Tower and explore:
- Nippon Maru Memorial Park: Right outside the tower, see a beautiful historic sailing ship.
- Access: 3 minutes walking from Landmark Plaza.
- Google Maps:
- Cup Noodles Museum Yokohama: A fantastic, tactile museum where you can design your own cup noodle packaging.
- Access: About a 10-minute walk from Landmark Plaza toward the waterfront.
- Google Maps:
- Yokohama Red Brick Warehouse (Akarenga Soko): Historic brick customs buildings now converted into boutique shops and cafes.
- Access: A 15-minute walk from Landmark Plaza or a short ride on the tourist loop bus.
