Hachiko
Hachiko , an akita used to accompany his master to the local train station near Tokyo in Japan every day.
One day in May 1925, his owner died at work, so the dog left the station alone that evening. But for the rest of his life, he visited the station every data in hope to be able to greet his master.
After nine years, when Hachiko died, a statue was erected in his memory.
