Principal Ganjō is a supporting character in the anime Apache Yakyūgun, which takes place at a small high school in the isolated mountain village of Inosaru Village, a community so unruly that outsiders call it Apache Village. The character's name appears in Japanese materials as Iwaki, with Principal Ganjō being an alternate rendering used in some English-language listings. He is the principal of the rundown local high school, an institution with very few students, and the series establishes that he and his granddaughter Chieko, who teaches alongside him, make up the entire teaching staff. In this capacity, Ganjō is the head of the school where the former baseball star Tsuyoshi Dojima arrives to coach a newly formed baseball team, making him the local authority figure who presides over the setting in which most of the story unfolds. His most significant relationship is with Chieko, his granddaughter, who works with him at the school and has close contact with the students. The principal functions as a background adult presence in the narrative rather than a central figure, and the story does not develop a detailed personal history, distinctive personality traits, private motivations, or notable abilities for him. His role is defined primarily by his position at the school and his family connection to Chieko, and he remains a minor but recurring part of the village community that surrounds the Apache baseball team.
