Hachikō, Japanese dog famous for his loyalty to his owner (d. 1935)
Hachikō (ハチ公, 10 November 1923 – 8 March 1935) was a Japanese Akita dog remembered for his remarkable loyalty to his owner, Hidesaburō Ueno, for whom he continued to wait for over nine years following Ueno's death.Hachikō was born on November 10, 1923, at a farm near the city of Ōdate, Akita Prefecture. In 1924, Hidesaburō Ueno, a professor at the Tokyo Imperial University, brought him to live in Shibuya, Tokyo, as his pet. Hachikō would meet Ueno at Shibuya Station every day after his commute home. This continued until May 21, 1925, when Ueno died of a cerebral hemorrhage while at work. From then until his death on March 8, 1935, Hachikō would return to Shibuya Station every day to await Ueno's return.

During his lifetime, the dog was held up in Japanese culture as an example of loyalty and fidelity. Well after his death, he continues to be remembered in worldwide popular culture, with statues, movies, books, and appearances in various media. Hachikō is known in Japanese as chūken Hachikō (忠犬ハチ公) "faithful dog Hachikō", hachi meaning "eight" and -kō which originates as a suffix once used for ancient Chinese dukes; thus, Hachikō could be roughly translated as either "Mr. Eight" or "Sir Eight".
