In 1924, Hachiko was brought to Tokyo by his owner, Hidesaburo Ueno, a professor in the agriculture department at the University of Tokyo. During his owner's life Hachiko saw him off from the front door and 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 didn't return on the usual train one evening. The professor had suffered a stroke at the university that day. He died and never returned to the station where his friend was waiting.

Hachiko was given away after his master's death but he routinely escaped, showing up again and again at his old home. After some time, Hachiko realized that Professor Ueno no longer lived at the house. So he went to look for his master at the train station where he had accompanied him so many times before. Each day, Hachiko waited for Professor Ueno to return. And each day he didn't see his friend among the commuters at the station.

Hachiko became a permanent fixture at the train station, which eventually attracted the attention of commuters. Many of the people who frequented the Shibuya train station had seen Hachiko and Professor Ueno together each day. Realizing that Hachiko waited in vigil for his dead master, their hearts were touched. They brought Hachiko treats and food to nourish him during his wait. This continued for 10 years, with Hachiko appearing only in the evening, precisely when the train was due at the station.
