History[]
Part I[]
Early Days Arc[]

Miyazaki talking to Hiroko about Ippo.
When Hiroko Makunouchi informed Miyazaki that Ippo Makunouchi was starting boxing and mentioned how she was against it, Miyazaki claimed that she can't deny the blood, as Kazuo Makunouchi was usually calm, but his arm was the best around. Miyazaki was impressed after seeing Ippo carry a large amount of ice coolers full of fish in a wavy environment. He told Ippo that he thought he would be a rebellion, but his kind behaviour may vanish with boxing, requesting for him to continue helping his mother.

Ippo asked Miyazaki if he knew any doctors that could look at his broken hand to see if it were possible for him to fight Takeshi Sendō. Miyazaki gave Ippo the name of Tomoko Yamaguchi.
Two Rookie Kings Arc[]

Miyazaki giving some advice to Ippo.
When Ippo returned home after Mamoru Takamura's title defence, his mother was returning home after taking a group of customers (with Miyazaki) night fishing. As Ippo helped unload the boat, Miyazaki learned that Ippo had no upcoming match set yet, despite being ranked 10th in Japan. He also noticed that Ippo's became much more confident in the past 2 years. He wondered if Ippo is more popular with girls as he gets more famous, and he told Ippo to be careful not to get tricked by them. As he began leaving, he told Ippo that he will be cheering for him to become the Japanese featherweight champion, and that he should take his mother sometime.
Class A Tournament: Speed Star Arc[]

Miyazaki telling Ippo about Hiroko.
After Ippo learned his mother collapsed, he rushed toward the hospital where he met Miyazaki. Miyazaki told Ippo that Hiroko was sleeping, and that she will need to be hospitalised for about a month. He mentioned that she fell down after they got off the boat, where it was from anaemia caused by overwork. He added that she is stubborn, where she probably didn't want Ippo to find out that she has been working too hard lately. As he leaves, he told Ippo that she should be tired and to let her rest for now.
First Step Arc[]

Miyazaki told Ippo they decided to be his cheering squad for his title defence. Miyazaki displayed a banner to Ippo for cheering him on that they planned to bring with them for the match. Umezawa and Hiroko also gave Ippo a new pair of red boxing trunks with stars on them along with new boxing shoes.
Part II[]

Miyazaki telling Umezawa that Ippo was raised on the seas.
As Miyazaki and the rest of the fishing crew get ready to set out to the water, Umezawa warned the crew about the rough waters. When Umezawa wondered how Ippo was able to stand on the worst part of the boat, Miyazaki explained that he was raised on the water, and commented how Ippo had learned to shift his weight perfectly. When it was time to get ready to fish, Miyazaki threw up along with the rest of the crew due to the rough waters.

After returning to the Makunouchi Fishing Boat from a fishing trip, Miyazaki and the other customers learn that Ippo has relinquished his JBC featherweight belt to head for the world stage, and Manabu Itagaki would be taking Ippo's vacant title. Miyazaki told Hiroko how Ippo is going to be the best in the world as he will become a world champion, however, Hiroko claimed that she hasn't seen any of his matches, but knows he works hard. Miyazaki suggested for her to go see at least his world title match, and that he and rest of the fighting crew would go.

Second Step Arc[]
While fishing on the boat, Miyazaki learned that Ippo was becoming a second, disappointed because he wanted to see him fight one more time.

Though disappointed after hearing Ippo not boxing anymore, he noted how Hiroko looked healthier due to Ippo helping out more.
Importance of the Support Role Arc[]
When Miyazaki saw Ippo was trying to look for something from the boat, he told him that he should get higher up for a better look. However, Ippo claimed that his friend was far across the ocean, so there was no way for him to see him from the boat.
Keith Dragon Arc[]
