Located at Shibuya, Tokyo, the statue of Hachiko won't be hard to find. It's located just in front of Shibuya train station and near to the famous Shibuya crossing.
The story is back in 1924, a Professor of The University of Tokyo, Hidesaburo Ueno, adopted an abandoned dog, which he named Hachiko. The dog was a Akita breed. Hachiko used to greet the Professor everyday whenever he come back from work at the same time at the Shibuya Railway Station. Hachiko and the Professor followed this routine everytime until May 1925, when the Professor died and never returned home. But Hachiko waited there for the Professor to return home for the next 10 years (some say 9 years) :-(
Other commuters and shops owners nearby who had seen the bond of the dog with the Professor felt sorry for it and started feeding it at the station. Hachiko finally died on March 8, 1935. His remains have been preserved at the National Science Museum of Japan, Tokyo.
Today the Japanese people would refer to Hachiko to inspire their children. And in honour of Hachiko, his statue was made at where he waited for the Professor to return home.
