The advert is part of a series featuring athletes standing alongside some of the Japanese capital's most famous landmarks.

Tani's campaign is the fourth created by the Tokyo 2020 Organising Committee, with a fifth to follow soon.

It features Japan's first Para-triathlon world champion in front of Rainbow Bridge, a feature of the Tokyo 2020 triathlon courses.

Six years ago, Tani gave a presentation in front of the International Olympic Committee as part of her country's bid for 2020.

"This area in Odaiba, from where I can view the Rainbow Bridge, is going to host the triathlon events, and is also one of my usual practice places," she said.

"I would like to cherish this process over the next year, imagining the moment when I will be running with a lot of support and cheering from people in my hometown. 

"I hope all of the Paralympic venues will echo with everyone's support."

Tani competes with a prosthetic limb as her right leg was amputated below the knee due to osteosarcoma.

In March 2011, her hometown Kesennuma was damaged by the Great East Japan Earthquake and tsunami, and she was unable to practice for some time. 

The Tokyo 2020 Paralympics are between August 25 and October 6.
