The winning team is not Meihou or Daiei Gakuen. Inoue also mentioned he did not want a team that most people would deem historically strong to win. In 2017, an interview with Inoue Takehiko revealed that Kainan was no.Since Kainan went to the finals, it is easy to realize that either they won against Aiwa Gakuen in the semifinals or Aiwa failed to meet them and lost in the quarterfinals.Since Hanamichi was the protagonist of the series and got hurt during the game against Sannoh, being unable to play for the rest of the tournament, the manga doesn't focus on continuing the championship, only including some facts like Shohoku losing to Aiwa Gakuen in the third round and Kainan getting the #2 place.One possible explanation would be that the name of the team was wrongly translated to Mamita Nishi and then changed to Umamiya. According to the manga, they win against Umamiya from Iwate prefecture but said team simply does not exist when we first see the National High School Tournament bracket. There seens to be some error in translation or in continuity in Kainan's first match during the tournament second round.Tobita Daini vs Nakamura Kitasho (? - ?).Urayasu Shougyou vs Yuki Industries (93-58).

Aiwa Academy vs Yokotama Industries (103-58).
