Organisers have adapted the lyrics of the song "Tokyo Gorin Ondo", which was originally composed by Masao Koga and written by Takashi Miyata for the Tokyo 1964 Games.

They now include references to Paralympians, while special choreography has also been created.

The official version of the song will be sung by Sayuri Ishikawa, Pistol Takehara and Yūzō Kayama.

Tokyo 2020 President Yoshirō Mori spoke about the song on Monday (July 24), when numerous promotional events were held across Japan to mark three years to go until the Opening Ceremony of Tokyo 2020. 

"This summer, we are producing a Tokyo 2020 happi, or traditional Japanese jacket, a special yukata, or casual kimono, and we are releasing 'Tokyo Gorin Ondo 2020', a dance song in traditional Japanese style celebrating the Games," he said.

"We have produced these in the hope that many people all over the country will wear the Tokyo 2020 summer festival costumes and dance to the song.

"The common theme of these engagement initiatives this summer is 'Happy and Peace'.

"Through this, we are expressing the wish that many people, old and young, men and women, will dance and feel happy when the Tokyo Gorin Ondo 2020 song is played.

"A video is available on our website, through which people can learn the song and the dance routine.

"We hope that people around the world can thus have a glimpse of Japanese culture."

The theme song for the Rio 2016 Olympic and Paralympic Games was entitled "Heart and Soul".

The song was produced by Brazilian DJ duo Tropkillaz, comprised of André Laudz and Zé Gonzalez, and featured lyrics from rapper Projota and pop singer Thiaguinho.
