Onitsha operates a traditional government headed by the Obi, the titular head of the town who is assisted by Ndi Ichie, titled red cap elders or chiefs. Among these are Ndi Ichie Ume, who are the First Class Chiefs. The Ndi Ichie are classified into six, namely: Onowu Iyasele, Ajie Ukadiugwu, Odu Osodi, Onya Ozoma, Ogene Onira and Owelle Osowa, with Onowu Iyasele as the traditional Prime Minister. There are also other Ndi Ichie, who are ranked second class, known as Ndi Okwa and third class, known as Ndi Ichie Okwareze. The Ndi Ichie serve as Council of Advisers to the Obi who solicits their advice in major decisions he takes in the Kingdom.
When the ruling Obi joins his ancestors, the Onowu Iyasele takes charge until a new Obi is enthroned.
Once a year in October the kingdom of Onitsha holds the Ofala Festival which coincides with the traditional New Yam festival held in many parts of Igboland. It is a way for the people of Onitsha to keep their culture alive and it has become a major event that draws visitors from far and wide to the city.
