Tutsa tribe is one of the main tribal communities in Arunachal Pradesh. They are the inhabitants of the Tirap district.

Moreover, the women wear necklace of beads and they are expert in weaving and beads work. Interestingly, the traditional ceremonial dress for the men includes the decorated hat and attractive dresses and ornaments of women.

In the Tutsa tribal group the family system is patriarchal in nature. The father is the head of the family and at the old age, after the consent of family members, he hands over the charge of the household activities to the eldest son. In some exceptional cases the son can also establish a separate family or household of his own after marriage because of increase in the number of the family members. The Tutsas have a chieftainship system in their society. The chief of the Tutsas are called Lowang and their chieftainship system follows the law of primogeniture. The chief is the paramount authority of the village. The traditional village council is known as Ngoangthun.
