Some Miyako still practice matriarchal religious rites with associations of guardian priestesses and a chief priestess. "...Ceremonies and masks vary according to each village, they share a common animist basis: female elders are entrusted with the responsibility of guarding a village’s sacred forests, wells, springs and oracles. The faith, emphasizing nature’s divinity and ancestor worship, shares common threads with the world’s surviving animist religions in Africa and Asia."

Coinciding with the harvest season, are "...ceremonies featuring Paantu-like gods [that] are closed to outsiders. The handful of published photos show two figures covered in grass and wearing bearded masks with long noses and bulging eyes — masks that, experts say, originally came from Papua New Guinea."

Paantu masks are "...wood-carved...of a fearsome elongated face, with a large forehead, small eyes and a thin rectangular mouth."
