"Wassai", a traditional Japanese festival chant, is a coined word that combines the two Japanese words "wa" and "sai".

"Wa" can be depicted in writing with several different characters, each with a different meaning, including 話 ("talk"), 輪("circle"), 環 ("unity") and 和 ("peace").

"Sai" means festival in Japanese.

Organisers claim the Nippon Festival will provide children from Japan and around the world the chance to encounter each other in a traditional Japanese festival atmosphere.

"Tokyo 2020 hopes the festival will be a place for the meeting of hearts and minds, allowing friendships among people from different backgrounds to be made in Tokyo and fostering a sense of what the Japanese call 'wa' (harmony)," a statement from the Organising Committee reads.

The "Wassai" programme is due to take place at Shinjuku Gyoen Landscape Garden in Tokyo on July 18 and 19.

Further information on the programme, including team members featuring in its "dance" and "music" events, its content and registration details, are set to be announced in April.

Programme director Komei Sugano and many renowned musicians and dancers will take part in the festival.

Students of Tokyo University of the Arts will assist with the design and production of artwork that will feature at the event site.

It will be supervised by Katsuhiko Hibino, dean of the faculty of fine arts and professor at the Department of Intermedia Art at the Tokyo University of the Arts.

"Wassai" will be a place for interaction and dialogue that, it is claimed, will allow a memorable "wa" (circle) to be created.

The Nippon Festival, an official cultural programme of Tokyo 2020, will be held from the end of March to September 2020.
