More than 200 people from 24 related organisations in Hokkaido and elsewhere demonstrated various dances, music and rituals in three shows on the day.
The event was organised by the Foundation for Ainu Culture to express the Ainu belief that the world exists thanks to all beings, not only humans, who grow and support each other.
"I hope visitors experience the various attractions of Ainu culture and embrace the ideal of interethnic harmony," Yoshitaka Ito, state minister in charge of the expo, said in a speech.
