Currently, the North Tower is closed for renovations
One of my favourite observatories in Tokyo is the Tokyo Metropolitan Government Building. It mightn't be as high as Tokyo Tower or Tokyo Skytree, but like them it has some great views of the city. Tocho (as it is commonly known) was completed in 1991 and at 243 meters in height, it is one of Tokyo's tallest, and definitely one of its most iconic buildings. It is conveniently located in Shinjuku, and looks like a gigantic computer chip or a Gothic cathedral (so some people say). The views from it are great and the best thing about it, is that it is FREE.
The observatories are on the 45th floors of the building's north and south towers. In my opinion, the southern one is definitely the better of the two as it offers views of the central part of the city which the north can't match. Seriously, just get your camera out and click away. If you are need a list of things you can see from the south tower, here is my (incomplete) list:
1. Mt. Fuji (when the weather is fine);
2. Roppongi Hills;
3. Shinjuku Gyoen;
4. the skyscrapers of Nishi-Shinjuku;
5. Tokyo Bay;
6. Tokyo Dome;
7. Tokyo Gate Bridge;
8. Tokyo Tower;
9. Tokyo Skytree;
10. Yoyogi park (with Meiji shrine), and;
11. so many other famous skyscrapers in the city I won't even try to name them at all!
The north tower has far less of interest, so I only go to it at night, as it is usually open until 11 pm (for some weird reason the south tower usually closes at 5:30 pm). Just be aware that while you can get a great view of Mount Fuji, like the south tower, faces towards the western part of the city, which is mostly residential.
One really bad thing about the observation decks, but most understandable, is that tripods aren't allowed. However, there are ledges along the windows which you can use. You just need to be careful of people dropping their bags right next to your camera though!
The Tokyo Metropolitan Government Building is a fantastic place for photographers and I highly recommend it. Just check out the images here or on the net and I hope you'll agree. You can see the building's website here.
How to get there
The Tokyo Metropolitan Government Building is located in Nishi-Shinjuku, about a 10 minute walk from Shinjuku station, which is one of the major train stations in Tokyo. Shinjuku has so many train lines going through it so I doubt anyone will have a problem getting there.
Here is a Google Map to give you some help:
Both of the observatories open at 9:30 am. However, the north observation deck closes at 11:00pm (last entry is 10:30pm), while the south observation deck closes at 5:30pm (but is open until 11pm when the North Observation deck is closed).
The south observatory is closed the first and third Tuesday of every month and the north observatory is closed on the second and fourth Monday of every month.
If one those days listed above falls on a holiday, the observatory will be open but closed the following day. The observatories are closed over the New Year’s holiday season (29-31 December and 2-3 January). However they are open on January 1.
