Mori Art Museum (2026): Open Until 10 PM, the Three-Facility Confusion, and the Rooftop Nobody Mentions

Mori Art Museum — Honto Japan
Guide·August 7, 2026·15 min read·Sourced & cross-checked

The Mori Art Museum sits on the 53rd floor of a Roppongi tower and stays open until 10 PM — which makes it the rarest thing in a traveler's day: a serious cultural stop you can do in the evening, after everything else has closed. Last admission is 9:30 PM. There is no equivalent anywhere else in Tokyo.

What trips visitors up is that three separate paid things live in the same tower — the museum on 53, an observation deck on 52, and a gallery — reached through the same door and sold on separate tickets. Get that wrong and you either overpay or find yourself on the wrong floor. Here is the whole structure, with the current prices.

Honto check: Every price, time and rule below is from the museum's own site and the official Roppongi Hills art and observatory pages, checked August 4, 2026. 🚨 These prices belong to the exhibition running to September 23 and will change when the next show opens on October 31. And we do not tell you the rooftop Sky Deck is open — the official site has taken that section down, and we explain what we found below rather than repeating what other articles still say.

The three-facility problem, solved

One building, one entrance, three separate paid attractions:

  • Mori Art Museum — 53F. Contemporary art, major international exhibitions, open to 10 PM. This is the thing this article is about.
  • Tokyo City View — 52F. The indoor observation deck, sold on its own ticket: ¥2,400 at the counter, ¥2,200 online for adults during the current admission period. Note the child definition differs from the museum's — the deck charges from age 4, while the museum is free for junior high and under.
  • Mori Arts Center Gallery — 52F. A separate commercial exhibition space with its own ticketing, usually running something entirely different.

The combo ticket for the museum plus the deck is ¥4,300 at the counter or ¥4,100 online, against ¥2,300 plus ¥2,400 bought separately — so the combo saves you money and, more usefully, tells you the two are genuinely separate products. One line on the official site is worded ambiguously about deck access after viewing the exhibition. We are not going to resolve an ambiguous sentence by guessing: if you want both, buy the combo, or ask at the third-floor counter.

One nice detail buried in the FAQ: there is a free water station in the 52nd-floor corridor, and free museum Wi-Fi throughout.

Getting in (the entrance is not where you think)

A Japanese route-guide channel films the whole approach in 4K, starting at street level and reaching the observation-deck entrance at 3:49 and the 52nd floor at 5:18. Even with no Japanese, watching the walk once makes the entrance impossible to miss in person.

The tower entrance you walk past is not the way in. The route, in the museum's own words:

  • Find the Museum Cone — the glass structure at the base of the complex, past the large spider sculpture.
  • Go up to the 3rd floor, where the combined "Museum & Observatory Tickets / Information" counter sits. Everything is bought here.
  • Take a direct elevator to the 52nd floor, then the escalator up to the museum on 53.

From the subway it's three minutes from Exit 1C of Roppongi Station on the Hibiya line, with direct covered access through the complex, or six minutes from Exit 3 on the Oedo line. In August heat or rain, the Hibiya route is worth the extra thought.

The Tuesday trap, and the summer opening nobody knows about

Tuesday is not a closing day — it is an early close. The museum runs 10:00 to 17:00 on Tuesdays, last admission 16:30, against 22:00 the rest of the week. Turn up at 7 PM on a Tuesday expecting the famous late opening and you will find it shut, five hours early.

It is not even reliably true: the museum lists three specific Tuesdays this year that stay open until 22:00. Check the date you are going.

🚨 And the one worth planning around right now: on weekends and public holidays from June through September, the museum opens at 9:00 instead of 10:00 — and that includes the whole Obon holiday period, August 8 to 16. A 9 AM start on an Obon weekend is the emptiest this place gets all summer. (The shop inside opens at 9:30.)

The rooftop question, answered honestly

Every English-language article about this building mentions the Sky Deck — the open-air rooftop, 270 meters up, one of the few places in Tokyo where you stand outside at that height.

We are not going to tell you it is open, because the official site no longer says it is. When we checked on August 4, 2026: the entire Sky Deck block on the observatory's own homepage is commented out of the page's HTML — present in the code, deliberately not displayed — and the hidden text reads "Rooftop Sky Deck is closed until further notice." The Sky Deck section of the official FAQ is likewise commented out. The official floor guide lists only floors 2, 3, 52 and 53no rooftop level at all. The Japanese-side Sky Deck link returns a 403.

That is not proof it is closed forever, and we are not claiming it is. What it means is that the operator has taken the information down, so the prices, the bad-weather closure rules and the bag restrictions you will read elsewhere are historical. Ask at the third-floor counter on the day, and don't build your evening around it.

Tickets, rules and the fine print

  • Date and time specified. Tickets are sold for a designated slot in advance — but if slots have not filled, you can buy at the counter on the day. Same-day walk-up is realistic on a weekday evening.
  • No changes, no refunds. Once bought, tickets cannot be canceled, the type cannot be changed, the date and time cannot be changed, and there are no refunds or reissues. Buy the right slot the first time.
  • Online is cheaper by ¥200 for adults — worth doing purely for that, and it also skips the counter queue.
  • Bring ID if you are claiming the student or senior rate.
  • Free for disabled visitors and one companion each, on presentation of a disability certificate or equivalent government-issued ID at the third-floor counter, with no advance booking required.
  • One ticket, several shows. The exhibition ticket also admits you to the museum's smaller concurrent programs on the same day.
  • In the galleries: no touching works or cases, no phone calls, pencil only if you want to write, and no sketching.

What is on, and when the prices change

The current exhibition runs to September 23, 2026 and the museum states it is open every day during it. The next major show opens October 31, 2026 and runs to March 28, 2027. Ticket prices are set per exhibition, so everything quoted here expires with the current show — the October prices had not been published when we checked.

One current caveat on the deck side: part of the observation deck — the area facing Mount Fuji — is stated as inaccessible during the present period. If the Fuji view is why you were buying the deck ticket, that changes the math.

Where it fits in a Tokyo evening

The 10 PM close makes this the natural last stop of a day, which is the opposite of how most people schedule a museum. Pair it with dinner in Roppongi and go up at 8 PM, when the galleries are quiet and the city outside the windows is fully lit.

If the view rather than the art is the point, compare the alternatives before you buy: Shibuya Sky is the open-air rooftop everyone photographs, Tokyo Tower is the classic, and the Metropolitan Government Building gives you 202 meters for nothing at all. For building a day around it, see the 7-day itinerary and where to stay in Tokyo.

FAQ

How much are Mori Art Museum tickets?
For the exhibition running to September 23, 2026: adults ¥2,300 at the counter on weekdays and ¥2,100 online, rising to ¥2,500 and ¥2,300 on weekends and holidays. High school and university students are ¥1,400 / ¥1,300 on weekdays; visitors 65 and over are ¥2,000 / ¥1,800; junior high school students and younger are free. Add ¥500 for the AI audio guide. Prices are set per exhibition, so they will change when the next show opens on October 31 — check before you go.
Is the observation deck included with a museum ticket?
Treat them as separate purchases. The museum (53F) and Tokyo City View (52F) have separate price tables and are sold as separate ticket categories, and there is a combo ticket at ¥4,300 at the counter or ¥4,100 online — which is cheaper than buying both separately, and would make no sense if one included the other. There is one ambiguously worded line on the official site about admission to the deck after viewing the exhibition, and rather than guess at it we suggest asking at the ticket counter on the third floor, where you buy either way.
What time does the Mori Art Museum close?
10 PM most days, with last admission at 9:30 PM — unusually late for a major museum and the single best reason to go. Tuesdays are the exception: 10:00 to 17:00 with last admission at 16:30, though the museum lists three specific Tuesdays this year that stay open until 22:00. Note this is an early close, not a closing day — during the current exhibition the museum states it is open every day. There is also an extended opening this summer: 9:00 to 22:00 on weekends and public holidays from June through September, including the Obon period from August 8 to 16.
Can you take photos in the Mori Art Museum?
Don’t assume you can. The official English FAQ says photography is not usually permitted in the galleries, though photo spots may be available at some exhibitions; the Japanese version phrases it as varying by exhibition. Both direct you to the signage at the gallery entrance, which is the answer that actually counts on the day. Unauthorized photography and video are listed as prohibited, along with touching works, phone calls in the galleries, and any writing implement other than a pencil. Sketching is not allowed.
Is the Sky Deck open?
We can’t tell you, and we would rather say so than guess. As of August 4, 2026 there is no live Sky Deck information on the official site: the entire Sky Deck section is commented out of the page’s HTML, the floor guide lists only floors 2, 3, 52 and 53 with no rooftop level at all, and the Japanese-side Sky Deck link returns a 403. Every English article that quotes a Sky Deck price is quoting historical information. Ask at the third-floor ticket counter on the day.
How do you actually get in?
This is the part that confuses people, because the entrance is not at the base of the tower you can see. You go through the glass structure called the Museum Cone, take it up to the ticket counter on the third floor, buy there, take a direct elevator to the 52nd floor, and then an escalator up to the museum on 53. The Cone is a three-minute walk from Exit 1C of Roppongi Station on the Hibiya line, with covered access through the complex, or six minutes from Exit 3 of the Oedo line.
