Okita Juuzou

Japanese name:	沖田十三
Nickname:	Captain Okita, Juzo Okita

Juzo Okita the stern captain of the Yamato, utterly devoted to his mission to save Earth from the Gamilus threat, even at the cost of his own life. He is in fact dying, and becomes increasingly ill during the course of the first season, but remains convinced that he will live to see his home world again. He regards Susumu Kodai almost as a replacement for the son he lost in battle, and sorely regrets his son's death in battle at Pluto, along with the apparent death of Kodai's older brother, Mamoru. Even when his illness leaves him bedridden, he remains a source of advice to the crew, and to Kodai in particular.

Seiyuu: Sugou Takayuki, Naya Goro
