While surfing through the net I came across across this wonderful story of Hachikō the faithful dog. Hachikō is a Japanese Akita dog. In 1924 Hidesaburō Ueno, a professor took Hachikō as a pet. Hachikō used to greet its master everyday at Shibuya Station when the professor returns from work.
In May 1925, the professor suffered from cerebral hemorrhage and died and never returned to the station. Hachikō continued to wait at the station everyday for its master for the next nine years. This faithful act of Hachikō attracted the attention of the commuters. This faithful act of Hachikō was honored by the Japanese and a bronze statue was erected at the station. Also one of the exits at the station is named as 'Hachikō Exit'
