Founded on the shores of the River Ase, Igbuku is one of the last Isoko towns sharing a common boundary with the Ukwuani Kwale speaking areas of Delta State, Nigeria. Igbuku shares a common boundary with Ofagbe, Ovrode, Ibrede, Aboh, and Ashaka. The town is made up of descendants from Isoko and Kwale speaking founders who have so intertwined in intermarriages, that almost everyone from the town can trace to a mixed ancestry. Most early founders were from Ellu, Ovrode, and Aradhe hence most people trace their ancestry to Ellu, Ovrode, and Aradhe. There are also migrants from Ellu, Ofagbe, Ibrede, and Aradhe. Isoko language is the main means of communication, but ukwuani names are common. Igbuku is one of the Isoko towns where the Umahun Masquerade is paraded in Isokoland.
Igbuku Town is ruled by the Ozu, who is a recognized, gazetted traditional ruler in Nigeria. Igbuku's population is 3,500. The town has a primary school, post office, and a maternity/dispensary. The roads are passable by car with clear roads to Ibrede, and a new bridge to Aboh.
