Nyokum Festival is a vibrant festival by the Nyishi tribe to worship their ancestral spirits and Mother Earth. The term "Nyokum" is a combination of 'Nyo' (land) and 'Kum' (gathering), which means a sacred people's gathering for prosperity and blessings. This ancient festival is celebrated with traditional dances, prayers, and rituals to call upon Uyus, the spirits, for protection and success. It is a moment when Nyishi celebrate their cultural identity and oneness as people.

Nyokum celebrations feature the Rekham Pada dance, a simple yet graceful dance performed by Nyishi women. Both men and women join, singing folk songs to the beat of gunga and talum instruments, which are also played at weddings. The traditional attire includes eri robes and bead jewelry for men, and par ej dresses for women, with bamboo headdresses. This dance reinforces the Nyishi’s cultural identity and their connection to heritage.
