Can stories about pets or famous animals illuminate important aspects of a country's culture, its value system? The story of Hachi can.
Japan's most famous dog was Hachi, an akita, who met his master at a train station every day and went to the station daily for years after his master's passing. There are a number of books about Hachi, including:

Some teachers have used Hachiko: The True Story of a Loyal Dog by Pamela Turner with elementary school students.
http://www.pamelasturner.com/hachiko__the_true_story_of_a_loyal_dog_67470.htm The website includes information for teachers.
And many have seen the film starring Richard Gere that is an adaptation of the story. (Gere also starred in Shall We Dance, an adaptation of a popular Japanese film.)
