Dog's loyalty to man is known in the wide world. Undoubtedly, the most famous example of this is the character of the Hachiko dog, who was brought to Tokyo by its owner, a professor at the University of Tokyo. Hachikō escorted his master to the station every day and waited for him in the evening. Unfortunately, on May 1925 Ueno died suddenly in the workplace.
