Lonely Planet review
The Umeda Sky Building is Osaka's most dramatic piece of modern architecture, designed by Hara Hiroshi, who also designed Kyoto Station. Its twin-tower complex is like a space-age Arc de Triomphe, and from the top you can marvel at the incredible sprawl of humanity in all directions. Getting to the top is half the fun – for the final five storeys you take a glassed-in escalator across the open space between the two towers (definitely not one for vertigo sufferers). Tickets for the observation decks can be purchased once you get off the escalator.
Below the towers, you'll find Takimi-kōji Alley (滝見小路), a re-creation of an early Shōwa-era market street crammed with restaurants and izakaya (pub-eateries).
The building is reached via an underground passage that starts just north of both Osaka and Umeda stations.
