Hours North Observatory: 9:30 to 23:00 South Observatory: 9:30 to 17:30 (until 23:00 when North Observatory is closed) Admission ends 30 minutes before closing time Closed North Observatory: 2nd and 4th Monday of each month (or next day if Monday is a national holiday) South Observatory: 1st and 3rd Tuesday of each month (or next day if Tuesday is a national holiday) Both observatories: December 29 to January 3 (except January 1) and on occasional inspection days

The jr train is easy. Get off at Shinjuku station. It is a 10 minute walk to hotel from station. Very busy station. Ask the station attendants for directions and correct exit

As was said before just take the train and get off at shinjuku. Just remember that shinjuku station is enormous so make sure you take the exit on the same side as the building

According to the website in Japanese as of April 14 it says it should be open. I would also check again with a tourism official since this year Golden Week is an aberration with many places being closed. Sorry if this didn't help. Normally it is open from 9:30-11:00 daily.

Absolutely. The TMG building is about a 15 min walk to the west of Shinjuku Station. If your hotel is on the same side then it’ll be easy. If your hotel is to the east of Shinjuku station then you need to allow extra time to get across as Shinjuku is one of Tokyo’s largest stations and it can be challenging just to get on the right side. It took us about 30 mins from our hotel, Shinjuku Granbell, which is to the northeast of Shinjuku station. The TMG building viewing deck is free and worth a visit.

To visit the buildings themselves and have a tour of the government buildings that is accurate. But, the observation decks are open till late and run on a schedule which you can see on their website. Note that the south and north observation decks don’t open till late on the same nights and there is one day where one tower is completely closed depending on their schedules.

you can visit at your own leisure. No need for a tour.

Both are good. (if I remember correctly) northern one is better in the evening/afternoon because of the sunset.

Hi, this information is provided from the official Tokyo Metropolitan Government building website: South Observation Deck: 9:30 a.m. - 5:00 p.m. (until 10:30 p.m. on the 2nd and 4th Monday of each month) North Observation Deck: 9:30 a.m. - 10:30 p.m. Closed on 1st and 3rd Tuesday of each month (South Observation Deck) 2nd and 4th Monday of each month (North Observation Deck). If there is a national holiday on one of those days, the observation desk will open on that day, but will be closed the following day. Hope this helps! The night view at the North deck just opposite Hyatt Regency hotel is a must go if you are in Tokyo and the good thing it's free! 😉
