However, a participant taking part in an official Tokyo 2020 online session on Food Ingredients from the affected areas has refused to reveal details of what is being offered.

The presentation was part of a programme presented by the Recovery and Reconstruction Booth at the Main Press Centre at the Big Sight in Tokyo.

Nobuaki Kasai, director of Kasai Nousan, a company that produces vegetables in Iwate prefecture, said through a translator: "Since Japan is hosting the Olympic and Paralympic Games this time, I talked with my peers in the farming business that we too shall take part in the Olympics by acquiring the G.A.P. certificate and supplying food ingredients."

The Good Agricultural Practices (G.A.P) is an international scheme that encourages environment0al practices and sustainability.

Mr Kasai was asked for details on what produce his company was providing the Olympic Games.

"I am afraid there is the duty of confidentiality and I cannot disclose what products are being provided or to whom," he answered.

Mr Kasai did invoke the sustainability concept of the Games.

"Taking this Olympic and Paralympic games as a good opportunity, I hope to keep on working to realise the concept, 'Be Better Together'."

The presentation also featured the director of a winery in Miyagi and a representative of Fukushima farmers as part of a campaign to promote the recovery of the region.

Noboru Saito, representative of NPO Ganbaro Fukushima, Unity for Fukushima Farmers and Supporters said: "The Olympic and Paralympic Games will be a wonderful opportunity to get to know Fukushima’s reality and to have a familiar feeling with the place."
