Oyakata is the foreman of the Zenryoku construction crew, the group of hardworking rabbit builders around whom the series centers. His position places him in charge of the work site, where he oversees the efforts of the younger and less experienced members of the team. He is depicted as extremely hard working, carrying out his duties with a strong sense of commitment and setting an example through his own labor rather than through orders alone. His many years on the job have given him a deep practical understanding of construction work, and this experience allows him to serve as a mentor to those who are newer to the trade. He is the person the others turn to when they struggle, both because he can teach them what they have not yet learned and because he is capable of solving problems that the rest of the crew cannot handle on their own. Within the larger group he functions as a steadying and reliable presence, taking responsibility for keeping the team on track while also helping each worker improve. His role in the story is that of a supporting figure whose expertise and dependability underpin the activities of the main characters, and his defining qualities are his tireless work ethic and the depth of knowledge he has accumulated through long experience on the job.
