In 1924, Hidesaburō Ueno, a professor in the agriculture department at the University of Tokyo took in Hachikō as a pet. During his owner's life Hachikō greeted him at the end of the day at the nearby Shibuya Station. The pair continued their daily routine until May 1925, when Professor Ueno did not return. The professor had suffered from a cerebral hemorrhage and died, never returning to the train station where his friend was waiting. For every day for the next nine years Hachikō waited at Shibuya station.
É uma história real. Já tinha lido sobre ela em diversos livros que falam de cães, o último desses livros foi A História de Edgar Sawtelle . Hoje vi o filme e já há muito tempo que não me lembrava de chorar tanto. Vale bem a pena ver este filme e se gostam de cães levem os lenços de papel.
