In 1924, university professor Hidesamuro Ueno brought his dog, Hachiko, to Tokyo. Every morning Hachiko saw his master off at the front door, and every evening he greeted him at the nearby train station.
The professor died in May 1925, but the faithful dog still went to the station every day to wait for him.
He kept this up for 10 years.
The dog became a national sensation in 1932, when this story was published, and he’s since been the subject of books and movies. Today a bronze statue stands at Shibuya Station, where he kept his vigil.
