One of Ueno's students, Hirokichi Saito, who developed expertise on the Akita breed, saw the dog at the station and followed him to the home of Ueno's former gardener, Kuzaboro Kobayashi, where he learned the history of Hachikō's life. Shortly after the meeting, the former student published a documented census of Akitas in Japan. His research found only 30 purebred Akitas remaining, including Hachikō from Shibuya Station. He returned frequently to visit Hachikō, and over the years he published several articles about the dog's remarkable loyalty. In 1932, one of his articles, published in Asahi Shimbun, placed the dog in the national spotlight.
