- Darker and Edgier: He has a tendency to do this. When he took over directing duties on The Rose of Versailles, the tone of the show became notably darker and the pacing far more upbeat. The Black Jack OVA is much more explicit with violence than the manga.
- Dutch Angle: One of the most notorious users of this in anime. It's not a rarity to even see a diagonal Dutch Angle shot.
- The Ken Burns Effect: Whenever he used Limited Animation, this technique was his first choice to save budget.
- Pastel-Chalked Freeze Frame: Trope Maker.
- Rule of Drama
- Signature Style: All of the tropes mentioned, along with a distinctive camera pan that is repeated three times in different speeds. He also tended to use a warm color palette and stark lighting that became highly influential on Akiyuki Shinbo and Kunihiko Ikuhara. Additionally, in his works, a lot of birds are flying around.
- Split Screen
- World of Ham: His fast pacing and heavy stylization tends to invoke this.
