Bunkyo Civic Center Observation Lounge

This observatory can be accessed directly from Korakuen or Kasuga stations without setting foot outside, making it a perfect option for when it’s raining. You’ll love the panorama of Shinjuku from the 105m-high deck protruding from its spaceship-like office building, and more so because the slanted windows reduce glare and reflection from sunlight. You’ll get Mt Fuji on a clear day while dusk makes for a spectacular shot when the setting sun is in view – just keep your eye on the clock, though, as the deck closes at 8.30pm even though the building is open until 10pm.
