Quick Answer
Go between November 12 and December 25, 2026 if you want the full Marunouchi Bright Holiday program. The separate Marunouchi Illumination runs longer, from November 12, 2026 through February 14, 2027. Start at the Marunouchi Building beside Tokyo Station, see the main indoor tree, then walk part of Marunouchi-Nakadori Avenue. Check the official event page again before you go: the organizer says more locations, participatory content and limited-product details will be released in late October.
Last checked: September 22, 2026 (JST). This guide separates confirmed information from details that are still pending.
The two date windows are not the same
The most important planning point is simple: the branded holiday program ends before the street illumination does.
| Experience | Confirmed period | What is confirmed now |
|---|---|---|
| Marunouchi Bright Holiday | Nov. 12-Dec. 25, 2026 | A Harry Potter-themed holiday program across the Marunouchi area, including a main tree at Marunouchi Building and decorations or content at several buildings |
| Marunouchi Illumination 2026 | Nov. 12, 2026-Feb. 14, 2027 | Champagne-gold lights along about 1.2 km of Marunouchi-Nakadori Avenue |
If your Tokyo trip is after December 25, do not expect the complete branded program. You can still plan for the longer street illumination, subject to the organizer’s current information.

What is confirmed for 2026
The organizer has confirmed these core facts:
- The holiday program runs from Thursday, November 12 through Friday, December 25, 2026, with some content potentially following different dates.
- The main symbolic tree is planned for Marucube on the first floor of Marunouchi Building.
- The announced program uses a Harry Potter theme and includes a light-and-music presentation around the tree.
- The wider program is planned across Marunouchi Building, Shin-Marunouchi Building, Marunouchi Oazo, Marunouchi Brick Square and other parts of the Otemachi-Marunouchi-Yurakucho area.
- Marunouchi Illumination 2026 is planned along Marunouchi-Nakadori Avenue from November 12 through February 14.
The organizer has not yet published every stop, schedule or limited item. Its English page says the next detailed release is planned for late October. That is why this guide does not give an invented show time or a complete stamp-rally-style route.
A low-friction route from Tokyo Station

1. Start at Marunouchi Building
Marunouchi Building is directly connected to JR Tokyo Station, according to the building’s official access page. It is the strongest first stop because the organizer has already named its first-floor Marucube as the location of the main symbolic tree.
Do not start by wandering the whole district in search of every decoration. Go to the confirmed anchor first, then decide how much of the outdoor walk fits your time and the weather.
2. Move onto Marunouchi-Nakadori Avenue
The confirmed outdoor illumination follows Marunouchi-Nakadori Avenue for about 1.2 km. You do not need to walk the entire distance to get value from the evening. A shorter out-and-back section is often the better choice if you have children, limited mobility, shopping bags or a dinner reservation.
3. Add other buildings only after the late-October update
The organizer names Shin-Marunouchi Building, Marunouchi Oazo and Marunouchi Brick Square among the wider locations, but the exact content at every stop was still pending when this article was checked. Save the official page and build the final sequence only after the detailed map appears.
4. Finish where your next action is easy
End near Tokyo Station if you have a train to catch. If you are continuing toward Yurakucho, choose a route that does not force you to backtrack. The official Marunouchi building map is more useful than a fixed route copied weeks in advance because event details can change.
How long should you allow?
AI-generated illustration, not an image of the official 2026 installation.
Use this decision rule rather than a rigid itinerary:
- 30-45 minutes: main tree plus a short illuminated walk.
- 60-90 minutes: main tree, a comfortable section of Marunouchi-Nakadori Avenue and one or two additional confirmed locations after the map update.
- Longer evening: add dinner or shopping, but check each venue’s live hours separately. The event period does not mean every shop, presentation or building operates for the same hours.
These are planning allowances, not official program durations. Crowds, photography stops, weather and the final event map will change the real time needed.
Best choice by travel date
November 12 to December 25
This is the correct window for travelers who want the branded holiday layer and the street illumination together. Recheck the official page after the late-October release and again on the day of your visit.
December 26 to February 14
Plan for the street illumination only. Do not promise children or companions that the indoor tree, themed decorations or limited content will still be available.
After February 14
Treat the 2026-2027 winter event as finished unless the organizer publishes an extension. Use the Tokyo Station and Marunouchi Quick Guide for a general area visit instead.
Cold, crowds and accessibility
AI-generated illustration. Venue views and seating are not guaranteed.
Marunouchi is a business and shopping district, not a closed festival ground. Expect normal city movement around commuters, shoppers and diners.
- Wear a warm layer that is easy to remove indoors.
- Keep the route short enough that you can pause inside a connected building.
- Use official building and station maps for elevators and accessible entrances; do not assume the prettiest street-level approach is step-free.
- Avoid blocking the pedestrian flow for photographs.
- Check the live weather and operator notices before leaving your hotel.

Plan B if the event is crowded or details change
AI-generated illustration. It does not show a verified event route.
Use a three-level fallback:
- Keep the date, shorten the route. See the confirmed main tree, then walk only the nearest illuminated section.
- Keep the area, switch the focus. If the indoor feature is too crowded, use the longer outdoor illumination and take a warm break inside a connected building.
- Keep the evening, drop the event promise. If weather, crowd control or an official change makes the event impractical, use the Tokyo Station-Marunouchi area as a normal dinner and architecture walk.
The Tokyo Christmas Market 2026 guide covers a different experience with different venues and ticket decisions. Do not treat it as part of Marunouchi Bright Holiday.
What to check before you leave
- Is your visit on or before December 25 if you want the full branded program?
- Has the late-October detailed release been published?
- Are the exact stop, presentation and building hours confirmed for your date?
- Is your return train or dinner reservation compatible with the route?
- Is the weather suitable for an outdoor walk?
- Do you have a short indoor Plan B?
