Almost every museum in Tokyo shuts at 17:00 or 18:00. If a rainy day has already eaten your afternoon, that’s exactly when you need somewhere to be.
The Mori Art Museum, on the 53rd floor of Roppongi Hills Mori Tower, is open until 22:00 — and you can reach it from the subway without going outside. That combination makes it the most useful evening in this guide.
There’s one catch, and it’s unusual enough that we’ve put it before the practical detail.
Check that it’s open at all
The Mori Art Museum has no permanent collection on display. It programmes temporary exhibitions, and the official line is blunt:
“The Museum is closed to the public when there are no ongoing exhibitions.”
So unlike the Tokyo National Museum or Nezu, where there’s always something to see, this one can simply be shut between shows — not for a day, but for a changeover period.
Check the current exhibition before you travel across the city. At the time of writing, a Ron Mueck exhibition runs from 29 April to 23 September 2026, open every day.
The hours, and why they’re the point
- 10:00–22:00, with last admission at 21:30.
- Tuesdays: 10:00–17:00, last admission 16:30.
That Tuesday exception is easy to miss and catches people out, because Tuesday is also the day the Ghibli Museum and Miraikan close entirely. If you’re improvising on a wet Tuesday, Mori is open — but only until 17:00, which makes it an afternoon plan rather than an evening one.
On any other day, the 22:00 close is the whole proposition. Arrive at 19:00, when the daytime crowd has gone, and you have a major museum at a civilised density. Few things in Tokyo improve as much after dark.
You can get there without getting wet
The address is Roppongi Hills Mori Tower, 6-10-1 Roppongi, Minato-ku.
- Tokyo Metro Hibiya Line, Roppongi Station, Exit 1C — 3 minutes, with direct access to Roppongi Hills through the concourse.
- Toei Oedo Line, Roppongi Station — 6 minutes.
- Toei Oedo Line, Azabu-juban Station — 9 minutes.
Use exit 1C. The concourse connection means the Hibiya Line route is effectively an indoor walk, which is a rare thing in this guide — most of our recommendations still require a few minutes under an umbrella. Here you can go from train to tower without opening it.
Once inside, you buy tickets at the Museum & Observatory Tickets / Information counter on the 3rd floor, reached through the Museum Cone — the glass entrance structure. Then it’s the lift to 53.
What it costs
Prices are tied to the exhibition on show, so these are the current figures rather than permanent ones. Booking online saves ¥200:
| At the door | Online | |
|---|---|---|
| Adult, weekday | ¥2,300 | ¥2,100 |
| Student, weekday | ¥1,400 | ¥1,300 |
| Adult, weekend and holidays | ¥2,500 | ¥2,300 |
| Student, weekend and holidays | ¥1,500 | ¥1,400 |
Children are free.
This is one of the more expensive museums in our set — more than double the Tokyo National Museum’s ¥1,000, and nearly four times Miraikan’s ¥630. What you’re paying for is a single, heavily produced exhibition and the hours to see it in.
The view is a separate ticket
Here’s the part people get wrong.
Tokyo City View, the observation deck, is on the 52nd floor — one floor below the museum — and it is not included in a museum ticket. They’re sold separately.
A combo ticket covering both is available, and if you’re going up the tower anyway it’s the sensible purchase. But don’t assume the art ticket puts you on the observation deck, and don’t buy the observation ticket expecting to see the exhibition.
On a rainy night this is worth thinking about honestly: an observation deck in heavy rain and low cloud may show you very little. The museum doesn’t care what the weather is doing. If it’s properly wet, buy the museum ticket alone and save the view for a clear evening.
How to use it on a wet day
As an evening rescue. Your outdoor plan died at 15:00, you’ve eaten, and it’s 19:00 with nothing to do. Nearly everything else is closed. This isn’t.
As a quiet hour. Between about 19:00 and the 21:30 last admission, the galleries are markedly calmer than at weekend middays.
As a Tuesday fallback — with the caveat. Open when Ghibli and Miraikan are not, but only until 17:00.
Not as a Monday problem. The Tokyo National Museum, Nezu and Teien all close on Mondays. Mori doesn’t.
Before you go
- Check what’s on. No exhibition means no museum — this is the one that will waste your journey.
- Check the day. Tuesday means 17:00, not 22:00.
- Book online if you’re certain of the date; it’s ¥200 cheaper.
- Exit 1C and the concourse, so you stay dry.
- Decide on Tokyo City View separately, and skip it if the cloud is down.
