Hachikō
In 1924, Hidesaburō Ueno, a professor in the agriculture department at the University of Tokyo, took Hachikō, a golden brown Akita as a pet. During his owner's life, Hachikō greeted him at the end of each day at the nearby Shibuya Station. The two kept their daily routine until May 1925, when Professor Ueno did not come back to the train station. The professor had died of a cerebral hemorrhage. Each day for the next nine years, nine months and fifteen days, Hachikō waited for Ueno's return. He showed up at the exact time the train was due at the station.
