Tokyo Metropolitan Government Building

The Tokyo Metropolitan Government Building, known locally as Tocho, offers one of the best free observation experiences in all of Tokyo. Located in the Nishi-Shinjuku skyscraper district, this imposing 243-meter twin-towered building designed by renowned architect Kenzo Tange houses the offices of the Tokyo Metropolitan Government — and on the 45th floor of each tower, completely free observation decks provide stunning panoramic views that rival those of paid observatories costing thousands of yen.

The observation decks sit 202 meters above ground and offer 360-degree views of the sprawling Tokyo metropolis. On clear days, Mount Fuji is visible to the west, while the eastern views take in Tokyo Tower, Tokyo Skytree, and the high-rises of central Tokyo stretching to the horizon. The South Observation Deck is open from 9:30 to 21:30 and is the more popular of the two, featuring a cafe, souvenir shop, and the Tocho Omoide Piano — a public piano that anyone can play during designated hours, with each session limited to five minutes. The North Observation Deck operates from 9:30 to 17:00 and tends to be quieter. Both decks are closed on certain holidays and for occasional maintenance, so checking the official calendar before your visit is recommended.

What makes Tocho special beyond the free admission is the nighttime experience from the South Deck. While most paid observatories charge premium evening rates, here you can enjoy the glittering Tokyo cityscape after dark without spending a single yen. The later evening hours tend to be less crowded than the pre-sunset rush.

This observation deck is perfect for budget-conscious travelers, families, and anyone who wants a panoramic Tokyo view without the entrance fee. Plan to spend 30 to 45 minutes. The building sits directly above Tochomae Station on the Toei Oedo Line. Alternatively, it is a ten-minute walk from the west exit of JR Shinjuku Station through the underground walkway, which is convenient if you are already exploring the Shinjuku area. Omoide Yokocho, Shinjuku Gyoen, and Kabukicho are all nearby, making it easy to combine with a full Shinjuku itinerary.
