Shinjuku Mitsui Building, Shinjuku

(3.5/5 based on 140 reviews on the web)
Anyone with an interest in architecture will enjoy a trip to the top of Shinjuku Mitsui Building. Step into the one-time fastest elevators in the world, which travel at 540 m (1,771 ft) per minute as they whisk you to the free observation platform and sky lounge restaurants that wait at the summit. At 210.3 m (690 ft) tall, it was the tallest building in the city until 1974, when it was surpassed. Take note of the building's unusual floor plan; built in a triangluar shape with its corners cut off, each of its sides reveal a different view of the city (with the obervatory and restaurants on each side). You'll also notice that the building's triangular atrium extends the full height of the building, creating an impressive sight. Make Shinjuku Mitsui Building a centerpiece of your Tokyo vacation itinerary, and find what else is worth visiting using our Tokyo trip itinerary maker.

  • Near the Tokyo Metropolitan Government. Also known as triangular building. 51 F is a free observation deck. Mt. Fuji is beautiful sunset from here is great. Makena is off the beaten path.

  • I had a few hours hanging around in Shinjuku, went into the Shinjuku Sumitomo Bldg. Free admission to the observation deck, good look at the view of Shinjuku. 
  • It is a building built at the beginning of the skyscrapers of Shinjuku. The Middle stairwell is, triangle building. The stairwell opening from the top, can be looked at from the bottom. SW 51st floor of restaurant city and Mt. Fuji from Observatory for free;

  • Decent selection of restaurants in the basement area. Gets a little busy on weekdays but good on Saturday lunchtime.
  • Decent office tower, has a good selection of restaurants on the lower level if you just head outside there.
  • Good view and it was free to go to the top if I remember correctly
  • Good restaurants in the basement out of shinjuku crowd
  • Nice restaurants at the top
