Okamoto Tarō's mural, Myth of Tomorrow (1967), was commissioned by a Mexican luxury hotel but went missing two years later. It finally turned up in 2003 and, in 2008, the haunting 30m-long work, which depicts the atomic bomb exploding over Hiroshima, was installed inside Shibuya Station. It's on the 2nd floor, in the corridor leading to the Inokashira line.
