Otaki-san is a tourist found in the square throughout Professor Layton and the Last Specter. He gives Professor Layton and the team a handful of puzzles to solve, but sadly no valuable information. He is from Asia.
Otaki-san wears glasses, red suit jacket, lilac trousers and a white shirt. He also has long blue hair.
Otaki-san gives the following puzzles in Professor Layton and the Last Specter:
After completing the puzzle Angle Time, Otaki-san gives the course Mt Otaki for the Train mini-game.
"A shady tourist from a far-off Eastern land, Otaki-san is a rational man who regards the specter with skepticism. His views are a little different from the world at large, which makes him seem quite contrary at times."
- Otaki-san's judgement seems to be based off movies he watched. For example, if he saw a movie where people went boating and got eaten by a shark, he would not go boating.
