Faithfulness and perseverance have always been admiral traits throughout the world.  In researching something else I stumbled across the interesting story of Hachiko.
Hachiko was an Akita dog that was born in 1923 rural Japan. At age 1, a University  of Tokyo professor acquired him. The professor would commute to work by train and at the end of the day Hachiko would leave their house to greet the professor at the train station and the two of them would walk home.  One day the professor suffered a brain hemorrhage at work and died.  Each day for the next 9 years Hachiko appeared precisely when the train was due at the station looking for the professor.  Over time he attracted the attention of the other commuters who started to bring treats and food to nourish him during his waits. His story became a national sensation as a symbol of family loyalty for the people of Japan to strive to achieve.  Teachers and parents used Hachiko’s vigil as an example.  A bronze statue of him was erected at the train station.  He was present for the unveiling.  Eventually he was found dead on a street of natural causes.  He was cremated and his ashes were buried beside those of the professor.  His fur was preserved, stuffed and mounted and is on display at the National Science Museum in Tokyo.  During World War II the statute was recycled for the war effort but then a new one was erected after the war and is still present as a popular meeting place.  Books have been written and three movies made,  one being an American film starring Richard Gere.
