This is Hachikō - the dog who waited at a train station for 9 years after the death of his owner.
During his owner's life, Hachikō greeted him at the end of each day at the nearby Shibuya Station. But one day, Professor Ueno did not return. The professor had suffered a cerebral hemorrhage and died, never returning to the train station where Hachikō was waiting. Each day for the next nine years Hachikō awaited Ueno's return, appearing precisely when the train was due at the station.
This continued until the dog died in the 1930s.
