Hachikō, the faithful dog

Hachikō (November 10, 1923–March 8, 1935), known in Japanese as chūken Hachikō ("faithful dog Hachikō" ('hachi' meaning 'eight', a number referring to the dog's birth order in the litter, and 'kō', meaning prince or duke)), was an Akita dog born on a farm near the city of Ōdate, Akita Prefecture, remembered for his remarkable loyalty to his owner, even many years after his owner's death.
In April 1934, a bronze statue in his likeness was erected at Shibuya Station, and Hachikō himself was present at its unveiling.
Each year on April 8, Hachikō's devotion is honored with a solemn ceremony of remembrance at Tokyo's Shibuya railroad station. Hundreds of dog lovers often turn out to honor his memory and loyalty.
