The rooftop "Hiroshima Hills" viewing terrace of the 13-story Orizuru Tower(orizurutower.jp) provides an impressive panorama over the adjacent Atomic Bomb Dome and city, especially at sunset. You can fold your own orizuru (origami cranes; ¥100) and enjoy various interactive displays. The top two floors become a bar in the evenings.
You can ride a slide back to the ground floor or walk down and admire the murals created by nine local artists.
