Fujimoto

While Fujimoto seemed placed into the role of villain, but he is only ever acting in what he believes is best for Ponyo. However, he is strict to his daughter Ponyo, and it may come across as him trying to control his daughter rather than keep her safe. For Lisa he is kind of a creep, who mistakes him for spraying pesticide, which is actually the purest ocean water so he can survive on land. In his core he is a good man, who cares about his daughters. He is only over-pessimistic, he hates humans, because humans pollute the environment, and more specifically the sea. So he uses magic to purify the sea from the humans’ waste. For that purpose he creates potions and elixirs, which if mixed correctly he pours into a well in one of the rooms in his underwater harbour. Because of humanity's destructive behavior, he becomes over-pessimistic. His wife, Granmamare adds more optimism to his mind. The seniors get to know him better as the story progresses. For them, Fujimoto is a nice guy with strange behaviours, and one claims that he wouldn't allow anyone to be harmed.

Fujimoto is slender and appears to be 40-years old, but he may have lived much longer. He claims he was once human, which implies he underwent some changes in order to become the wizard he is now. This may be a clue as to why he has strange, bird-like markings on his cheekbones and around his eyes. He has long red hair like Granmamare and his daughters, with turquoise, almost green, eyes. He wears a very strange cerulean and white-striped suit with a magenta cravat. On his ears are golden, round earrings. Near the end, he wears a similar white-striped suit, although this time the cerulean stripes are a salmon red, and the cravat is yellow. Throughout the movie he wears a dark magenta coat with a gold clasp at the front. It's long sleeves have holes right where the inside of Fujimoto's elbow would be, and his arms are often through the holes. When upon land, he uses a contraption he explains is a humidifier, to wet the ground with pure sea water as he is walking along it. This may imply he cannot go on land comfortably without it, or may have a risk of death without it. Also, when seen by humans, he is described as appearing very strange and perhaps shady, or to be avoided. This is only assumed, as he means no harm to humans although he seems to dislike them, especially with the waste they throw into the ocean.
