The story of Hachiko, the purebred Akita dog, is a touching one and represents to many Japanese the very definition of devotion. Having been bought as a pet in 1924, Hachiko would walk with his master each morning to the local Shibuya station in central Tokyo and then return in the evenings to welcome him home. Except, one day in 1925, his master didn't return having been struck down at his work in Tokyo University by a fatal stroke. Despite this, for the next ten years, Hachiko continued to return to the station each evening to await his master's return.
But you can't keep an old dog down and, in 1948, a new statue of Hachiko was commissioned from the son of the original sculpture. In this c1952 photograph of Shibuya Crossing, in the left hand corner, you can see him sitting there, still waiting for his master to come home. If this image were taken today, Starbucks would be on the right and Shibuya Station out of picture to the left. And this is where it becomes even more interesting. Here Hachiko is clearly facing towards the crossing but today the statue faces away. And that's because, in 1989, he was relocated as the area underwent a minor re-developedment. In more ways than one, a moving story indeed.
