Ippo running back with Hachi, who Aoki and Kimura thought was a bear.

While the Kamogawa Boxing Gym members were visiting the Pension Yoshio for a training camp, Hachi jumped on Makunouchi Ippo, who Aoki Masaru and Kimura Tatsuya thought was a bear and ran. Hachi had Ippo, who did not know the way back, follow him back to Nekota. When Kamogawa Genji announced to everyone at the training camp that he would be splitting the group for individual training, Hachi followed Nekota, who visited each group during their training. Hachi saved Nekota when he slipped in a river and then while Takamura Mamoru was carrying Yagi Haruhiko, Hachi hopped on Nekota's back when Nekota was on Yagi's back.

On the final day of training camp, Takamura went out for a run with Hachi. On the way back, a bear appeared. Hachi growled at it, but began backing away from it. Takamura ended up fighting it, and knocked it out. When Takamura told everyone that he defeated a bear, no one believed him, but Takamura mentioned Hachi was his witness. When the Kamogawa gym members left, Hachi ran with Nekota to see them off.

When Nekota went to the Kōrakuen Hall for Takamura's title defence against Itō Takaaki, he brought Hachi with him. Nekota attempted to bring Hachi with him, however the employees would not allow it, leaving Nekota to be forced to leave him tied outside. After Takamura's victory, they ended up going to the Sugar Ray to celebrate the win. However, Nekota had forgotten Hachi, leaving him tied outside the hall for a long period of time.

The next day, Ippo ran into Hachi waiting outside of the Kamogawa gym while Nekota was passed out inside after drinking all night. When Mashiba Kumi stopped by to visit the gym, Hachi became excited to see Kumi, and gets petted. Ippo took Hachi along with him on his roadwork, while Kumi followed on her bike. After returning to the gym, Hachi was excited to see Iimura Mari. However, Mari commented that Hachi looked fat. Hachi then left with Nekota as he drove away in a delivery truck back to the pension.

When Nekota went to the Kōrakuen Hall to watch Ippo fight Sendō Takeshi, he hid Hachi in a large sack. During the first round of Ippo's match, Hachi got out of the sack shocking some of the crowd near them. Before round four began, Hachi barked from the crowd which made Ippo remember his training at the pension. Hachi then temporarily hid in the sack when employees came when they heard a dog bark. When Ippo defeated Sendō, Hachi went into the ring just in time to be captured in Ippo's victory picture. Hachi's actions during Ippo's title match earned his owner a lecture for three hours at the security office. Later, Hachi went with Nekota to the Sugar Ray to celebrate Ippo's win where Nekota gave one of Hachis puppies to ippo.

Hachi is a large white dog. He is possibly a mix between an Akita and an Alaskan Malamute (according to Morikawa himself).[citation needed] He usually has a dog collar on (which is shown as red in the anime.)


  • Hachi is named after Hachikō, a famous Japanese Akita dog known for it's loyalty to his owner. He continued to wait 9 years after his owner's death for him.
  • To honour the 100th volume, a limited number of Hachi and Wanpo plush dolls were released.
