The coach of Meiwa (Captain Tsubasa arc, chapter 18, page 10).

20 years ago he may have refused to go pro oversea, and could've thus become the first japanese pro soccer player (Captain Tsubasa arc, chapter 19, page 24).

Now he seems to be a heavy drinker, drinking alcohol early in the morning (Captain Tsubasa arc, chapter 18, page 10).
Still, he trained Hyuga and Sawada and Meiwa became good in a short period of time thanks to him (Captain Tsubasa arc, chapter 18, page 10).
He also trained Wakashimazu (Captain Tsubasa arc, chapter 26, page 96).
