Tokyo Metropolitan Government Building
This is the rare big-city observation deck that costs nothing, which makes it one of the best-value things you can do in Tokyo. The twin-towered government complex in Shinjuku has free observatories around 202 meters up, and on a clear winter evening you can pick out Mount Fuji on the horizon. It is not as polished as the paid towers, the queues can drag, and the windows are not floor-to-ceiling. But free is free, and the view is the real thing.

The best free view in central Tokyo, plus a free projection show on the building at night. Lower and plainer than the paid towers, but you cannot argue with the price.
Worth it for
- Budget travelers who still want a panoramic Tokyo view and a shot at Mount Fuji
- An easy evening combined with dinner and bars in nearby Shinjuku
You can skip if
- You want the highest, most polished observation experience and do not mind paying for Skytree or Shibuya Sky
- It is a hazy day with no chance of distant views and you have limited time
Tickets & tours for Tokyo Metropolitan Government Building
Which ticket should you buy?
The free observation decks
Tokyo's metropolitan government works out of this Kenzo Tange complex, and it opens observatories near the top of its two towers to the public at no charge. The decks sit around 202 meters up and give you a wide sweep over Shinjuku's high-rises, the sprawl beyond, and on clear days landmarks like Tokyo Tower, Tokyo Skytree, and Mount Fuji to the west.
Because it is free and central, it gets busy, and you ride a dedicated elevator up after a security check. The viewing floor has a cafe and a small shop, so it is an easy place to kill an hour. The trade-off versus paid towers like Skytree or Shibuya Sky is height and slickness: you are lower, the glass is older, and it feels like a public building rather than a designed attraction. For zero yen, that is an easy trade.
Day view versus night view
Go on a crisp, clear day if your goal is Mount Fuji. Winter mornings and late afternoons after rain tend to give the cleanest air and the best odds of seeing it. The daytime view is more about orientation: you can map out where Shinjuku, the parks, and the distant mountains sit.
At night it becomes a sea of lights, which photographs well but reflects badly off the windows, so press your lens close to the glass to cut the glare. The two towers historically opened on different schedules and one sometimes closes for events or maintenance, so if one deck is shut, check whether the other is open before giving up.
The projection mapping on the facade
Most visitors miss that the building itself is the screen for a free nightly projection mapping show, sometimes featuring a Godzilla sequence among other pieces. The 3D art is mapped onto a wall of the building and the shows run in the evening, repeating on a set cycle. It earned a Guinness World Records mention as a large permanent projection mapping display.
Start times shift with the seasons because they follow sunset: shows begin later in summer (around half seven) and earlier in winter (closer to half five), running until roughly half nine. You watch from the plaza outside, not from the observatory, so plan to do the deck and then come down for the projection, or the other way around. Check the current month's schedule before you go, since the timing moves.
Making it worth the trip
Pair it with the rest of Shinjuku. The complex is a short walk from Shinjuku Station and from Tokyo's nightlife districts, so it slots naturally into an evening that also takes in Golden Gai or Omoide Yokocho. Doing the free deck first and dinner after is a sensible order.
Manage expectations on the queue. At peak times, especially weekend evenings, you can wait a while for the elevator, and the deck can feel packed at the windows. Weekday daytime is calmer. If you specifically want the projection show, get there before the first start time so you are not jostling for a sightline once it begins.
