      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 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 crowd at the station.

     Hachiko became a permanent figure at the train station, which eventually attracted the attention of

many people. Many of the people who frequented the Shibuya train station had seen Hachiko and

Professor Ueno together each day. Realizing that Hachiko waited 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.

     Hachiko: The True Story of the Royal Dogs of Japan is Hachiko's story, as well as an informative

look at dog culture in Japan and the history and tradition of the Akita-ken, one of the most ancient,

beloved and faithful dog breeds ever.
