Tokyo Metropolitan Government Building Observatories

The Tokyo Metropolitan Government No. 1 Building, completed in 1991 to a design by Kenzo Tange, is the city hall of the world's largest metropolis and the best free view in Tokyo. Its twin towers, inspired by Gothic cathedrals and patterned like an integrated circuit, rise from the skyscraper district of West Shinjuku, and each holds an observatory on the 45th floor, 202 meters above the street. The South and North observatories open on alternating schedules, so one is almost always available: the South closes on the first and third Tuesdays of each month, the North on the second and fourth Mondays, and both close for building inspections and the New Year holiday. The South Observatory reopened in spring 2025 after renovation. Visitors take a dedicated elevator after a quick bag check and step out into a broad, open floor with windows on every side: the towers of Shinjuku close at hand, the green mass of Meiji Jingu and Yoyogi Park, the distant Skytree and Tokyo Tower and, on clear days, especially in winter mornings, Mount Fuji to the west. There is a cafe on the observation floor, and the South Observatory has a public piano decorated by Yayoi Kusama, which visitors may play. Admission is free, and the building is open from morning until 22:00, with last entry at 21:30. After dark, the building's east facade becomes the screen for TOKYO Night and Light, a free projection-mapping show recognized by Guinness World Records in February 2024 as the largest permanent projection-mapped display on a building; several shows run each evening, viewable from the Citizens' Plaza below without tickets.

Is a free view worth it when Tokyo has SHIBUYA SKY and Skytree? Yes, with the right expectations. The TMG observatories are enclosed and a little utilitarian, and the glass shows reflections at night, but the price is unbeatable, the view of Shinjuku's skyscrapers is the best close-up of the district, and the Mount Fuji view on clear winter mornings is as good as any in the city. They are ideal for travelers on a budget, families with children who need a quick win, and anyone staying in Shinjuku who wants to orient themselves on day one.

Plan the visit around the light. For Mount Fuji, come early on a clear weekday morning between November and February, when the air is driest. For the night view, come after dark and then go down to the plaza for the next projection-mapping show; the schedule varies by season and is published on the official site. Lines for the elevator form at busy times, especially on weekends and holidays and around sunset, but they move quickly. Check which observatory is open on your date before you go, and keep large bags to a minimum for the security check.

The building is about ten minutes on foot from the west exit of Shinjuku Station, through the underground passage, and directly connected to Tochomae Station on the Oedo Line. Combine it with an evening in West Shinjuku's towers, a stroll through Shinjuku Central Park, or a walk across the station to Omoide Yokocho and Golden Gai for dinner and drinks after the show. On days when both decks are open, choose the South Observatory if you want to see the Kusama piano; otherwise either gives a superb view, and the shorter elevator line is the better pick. The observatories are fully accessible, with elevators from ground level, so they work well for wheelchair users and families with strollers.
