Jan (Japanese: ジャン Jan) is a character of the day from The Pi-Kahuna.
Jan was a surfer from 40 years before the events of the episode, and was highly revered as a great surfer. He was the first person to have ever ridden the wave, Humungadunga (Japanese: ビッグ・チューズデー Big Tuesday), to the top of the rock in the ocean and plant his flag there. He had given his old surfboard to Victor—who idolized him—before heading off to surf the world.
