Umeda Sky Building

Built in an attempt to upgrade Osaka's somewhat downbeat Kita district, the project wasn't quite the hoped-for commercial success but this bizarrely shaped 40-story, 173-m building is still a city landmark. Take the escalator through midair to the rooftop observatory for an open-air view of Osaka, which is particularly impressive on a clear night. There is a lover's seat, where if you hold your partner's hand, and each hold a metal button on the seat, the ground around you lights up into a heart. You can purchase an engraved heart lock (¥1000) and attached it to the padlock wall around the seat (padlocks only available after 19:00). Observatory admission ¥2000, 9:30AM-10:30PM daily. The basement features a recreation of a Meiji-era street, with a few small restaurants and bars in appropriate style. There is also a small store downstairs where you can purchase quality mochi on the cheap.
