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.

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 during the exhibition that ended September 23 was ¥4,300 at the counter or ¥4,100 online, against ¥2,300 plus ¥2,400 bought separately — so the combo saved 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
It is not even reliably true: the museum lists specific Tuesdays with later closing — for the show opening October 31, 18:00 on November 3 and 22:00 on February 23, 2027. 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
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 53 — no 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 previous exhibition ended on September 23, 2026, and the museum is closed from September 24 to October 30 for exhibition preparation. The next major show, Mariko Mori: All That Shines, opens October 31, 2026 and runs to March 28, 2027, and the museum states it is open every day during it. Ticket prices are set per exhibition; the museum prices quoted here are the ones published for that show (rechecked October 7, 2026).
One current caveat on the deck side: part of the observation deck — the area facing Mount Fuji — is stated as restricted on October 28–30 and November 4–9, 2026, and the deck is closed on October 27 and November 10–12 (official page, checked October 7, 2026). 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.

Bottom line (2026) — A contemporary art museum on the 53rd floor that stays open until 10 PM, sitting above an observation deck sold as a separate ticket. One building, one entrance, three separate paid attractions — plus the Tuesday trap and an Obon early opening to plan around.

Checked August 4, 2026: the Mori Art Museum's own exhibition page and the official Roppongi Hills art and observatory information pages — the 53rd-floor location, the 10:00–22:00 hours with 21:30 last admission, the Tuesday 10:00–17:00 early close with its three stated exceptions, the June-to-September 9:00 weekend and holiday opening including the August 8–16 Obon period, the statement that the museum is open every day during the current exhibition, the full ticket price tables for the museum, the observation deck and the combo ticket, the audio-guide surcharge, the free admission for junior high students and under and for disabled visitors with one companion, the ID requirement for student and senior rates, the date-and-time ticketing with same-day counter sales when slots remain, the no-change and no-refund policy, the Museum Cone entrance route and the station walking times, the gallery rules on touching, phone calls, writing implements and sketching, the photography FAQ in both English and Japanese, the free 52nd-floor water station and Wi-Fi, the current partial closure of the Mount Fuji side of the deck, and the exhibition dates for the current and next shows. Deliberately not stated: anything asserting the Sky Deck's current status, price or rules (that section is commented out of the official pages and its link returns 403); whether a museum ticket admits you to the observation deck (one official sentence is genuinely ambiguous and the rest of the evidence points the other way); the photography rule for this specific exhibition; the complete prohibited-items list; the re-entry policy; and the audio-guide price for the exhibition opening October 31. Rechecked October 7, 2026: the September 24 – October 30 closure, the Tuesday exceptions, the deck closure and Mount Fuji–side restriction dates, and the museum prices for the exhibition opening October 31, 2026. Combo prices quoted here are for the exhibition that ended September 23.
