Tokyo Metropolitan Government Building

The Tokyo Metropolitan Government is the authority that runs the special wards, cities, towns and villages making up the Tokyo Metropolis, and this complex of three buildings is where it sits. The tallest of the three, Main Building No. 1, is 48 storeys and splits into two separate towers at the 33rd floor, which is why there are two observatories rather than one. Kenzo Tange designed it to read like an integrated circuit while borrowing the silhouette of a Gothic cathedral, and when it opened it was described as the largest city hall in the world.

The Tokyo Metropolitan Government's own English page states the purpose of the decks in a sentence that no commercial operator would write: they are places for visitors to deepen their understanding of Tokyo and of the metropolitan government's policies while enjoying the view. That is the whole business model. There is no ticket because there is no product; the room is a piece of civic infrastructure with a panorama attached, and the gift shop and cafe are concessions inside it rather than the reason it exists.

• Roof height 242.9 metres, 48 floors above ground and three below.
• Both observatories on floor 45, at 202 metres.
• Completed December 1990 at a cost of ¥157 billion of public money.
• Tallest building in Japan from 1991 until the Yokohama Landmark Tower passed it in 1993, and tallest by roof height in Tokyo until Midtown Tower in 2007.
• Floor area 195,764 square metres across the complex.

Two decks, one building, and the part people miss

Almost every account of this place treats the observatory as one attraction. It is two rooms in two towers, reached from the same first-floor lift lobby by two different lifts, with different hours, different closing days and different tenants on the floor. The south deck holds the gift shop TOKYO Mikke! and the Tocho Omoide Piano, an upright anybody may play; the north deck holds the cafe and shop SOCOCOCO and can be booked out for private events in the evening through the concession that runs it.

Walking to the wrong lift is the commonest way to waste twenty minutes here.

Read the row for the day you are going, not for the deck you have heard of. The south deck is the one almost every guide names, because it is the one open at night; the north deck is the one that saves the trip when the south is dark.

Two rules sit under that grid and both catch people out. The first is the holiday shift: when a first or third Tuesday, or a second or fourth Monday, falls on a Japanese public holiday, the deck opens that day and closes the following weekday instead. So a trip planned around a calendar of Tuesdays can still meet a shut door on a Wednesday. The second is that the closures are staggered deliberately, and the north deck extends to 22:00 precisely on the days the south is out, which means the building as a whole almost never loses its evening view.

There is one annual exception worth knowing if you are here in early March. On the Sunday of the Tokyo Marathon the decks open from about 11:00 rather than 09:30, because the course runs past the building and the plaza is given over to the start. The city announces it on the same observatory page each year.

The days nobody publishes in advance

Building inspection days are the gap in the schedule. The metropolitan government reserves them for statutory checks of the tower's systems, closes both decks and the car park with them, and announces each one on its own news feed rather than on a published annual calendar. One recent example, a Saturday in May, took the whole of Main Building No. 1 out of service for an electrical inspection.

There is no way to see them a month ahead; the only reliable check is the observatory page itself, or the closure account the city runs on X at @tocho_tenbou, which it names as the place sudden weather closures are posted.

The room is a single circular floor with windows all the way round, a shop, a cafe and, in the south tower, a piano. There is no route through it and nothing to read but the photographic panels naming what you are looking at, so the time it takes is the time you choose to stand there.

The queue figure is the operator's own and it is unusually candid: the observatory page states that visitors are lining up 20 to 30 minutes to get in, and that the wait varies with the weather and the hour. It also publishes a live three-colour reading, blue for a wait of 0 to 5 minutes, yellow for 5 to 30 and red for over 30, which is the single most useful thing to check on a phone before you cross the plaza. Our own routing from the two: arrive in the first hour after opening for blue, or after 20:00 on the south deck, when the queue has thinned and the city is fully lit.

North-east is the direction people photograph without knowing what they are looking at: the Skytree stands alone on that side of the city, 634 metres of it, with the low roofs of the old east wards spread underneath. South-east looks over the national garden and the forest of Meiji Jingu, the two green blocks that interrupt the grid. South-west is the near view, the Shinjuku Park Tower and Tokyo Opera City close enough to read their floors.

West is the one people come for.

Mount Fuji, and the months it appears

The metropolitan government's own page is specific about this and does not oversell it. Fuji lies due west, and the page names December to February as the stretch when the temperature is low, the air is clear and the mountain can be seen on many days. It does not publish a percentage, and neither will we.

What follows from it is a plan: if the mountain is the reason you are coming, take the north deck on a cold, bright winter afternoon rather than the south deck at night, because the north closes at 17:30 and that is when the light is on the right side of the sky anyway. Between June and September, expect haze and treat the mountain as a bonus.

What the free deck does not give you

It is one room of windows, and the windows do not open. There is no open-air section, no glass floor, no ramp climbing higher into the structure, and photography with a tripod is not permitted, which the city states plainly on the same page. If you want the wind on your face, that is the open rooftop in Shibuya and it costs money.

If you want the height that makes buildings look like a model, that is the Skytree. This is a working government building with a very good window, and it is honest about being exactly that.

Do not leave the plaza when you come down. After sunset the building's own face becomes the attraction: Tokyo Night & Light projects across 13,904 square metres of the facade, from the 4th floor to the 32nd, and in February 2024 Guinness World Records recognised it as the world's largest permanent architectural projection-mapped display. It runs nightly, year round, in several short performances from sunset until roughly 21:30 to 21:45, and the programme is made by Japanese and international artists and changes, so two visits are not the same show.

It costs nothing, takes no ticket and needs no reservation. The practical consequence is that the best use of this building is a single evening rather than a daytime tick: up the south lift at about 19:00, forty minutes at the window while the grid lights up, back down, then stand in the plaza with the show on the wall above you. Add dinner in the alleys of Shinjuku afterwards and the whole sequence has cost the price of the meal.

The city publishes the current schedule on its own site rather than in a fixed timetable, because the number of performances shifts with sunset. Check it the day you go; the observatory page links it.

• There is an upright piano on the south deck that anybody may play, in three windows a day, 10:00 to 12:00, 14:00 to 16:00 and 19:00 to 21:00. The lid stays closed, the music stand cannot be used, and the operator asks that you do not post video of another player without asking them first. (Tokyo Metropolitan Government observatory page, read in Q3 2026.)
• The north deck can be hired. The concession that runs the cafe up there takes bookings for private events and parties in the room, through its own site rather than through the metropolitan government. (Tokyo Metropolitan Government observatory page, read in Q3 2026.)
• A QR view guide called TOKYO SKY GUIDE runs in the room in several languages, covering 32 named spots, and needs no app: the panels round the windows carry codes your phone camera reads. (Tokyo Metropolitan Government observatory page, read in Q3 2026.)
• On weekends and public holidays the second-floor entrance to the building is locked and you have to walk round to the main first-floor door, which is the reason a visitor occasionally reports the building 'closed' when the decks are open. (Tokyo Metropolitan Government observatory page, read in Q3 2026.)
• There is a decorative bamboo rake, a kumade, on display in the middle of the second floor. They have been sold at Tori-no-ichi festivals since the Edo period as charms for good fortune and good business, and this one is large enough to stop people on their way to the lift. (Tokyo tourism page for the building at gotokyo.org, read in Q3 2026.)

The short way is Tochomae Station on the Toei Oedo Line, whose Exit A4 is signposted at one minute on foot from the tower lobby. The Oedo Line reaches it from Shinjuku Station in a single stop, and from Roppongi, Iidabashi and Ueno-okachimachi without a change. The long way is JR Shinjuku Station, from which the metropolitan government's own access page gives about ten minutes on foot from the West Ticket Gate, through the underground concourse and up into the plaza.

There is also a Toei bus loop from the underground bus stands at the west exit, running weekdays only, with a stop named for Main Building No. 1.

Inside the building, both observatories are reached by dedicated observatory lifts from the first floor of Main Building No. 1, and there is no other route up. On closed days for the government itself, which means Saturdays, Sundays and public holidays, the second-floor entrance is locked and everybody uses the first-floor main door. The building provides a barrier-free route between the first and second floors for anyone who cannot manage stairs or an escalator, and lends both manual and powered wheelchairs, which you request from a guard at an information corner or at the observatory reception.

Fares above are the operators' own bands, read in Q3 2026; the ladder behind them is on the getting around page.

It is an evening stop, not a morning one, and it belongs at the end of a west-side day rather than in the middle of one. The reason is arithmetic: the south deck runs until 21:30 for entry and nothing else free in the city does, so spending daylight here uses up an hour that a garden, a shrine or a museum would use better. Put the shrine forest and the national garden in the daylight, eat in the district, then come up in the dark.

On a single day in the city, it is the free replacement for a paid rooftop, and the one-day plan uses it exactly that way. On a longer stay it is the second high view rather than the first: take a paid deck once for the height and the open air, and take this one on the night you would rather spend the money on dinner. The two-day plan puts it at the end of the west day, which is where it works best.

One last piece of sequencing. The projection show on the facade starts at sunset and runs to about 21:45, and the deck queue is at its shortest in the last hour before it closes. So the order that wastes nothing is deck first at around 19:00, then the plaza for the show, then dinner. Reversed, you arrive at the lift at 21:35 and find it shut.
