The Japanese company, founded in Tokyo in 1921, has become an official partner of the Games - the second domestic tier for sponsors linking up with organisers in the capital.

Yoshirō  Mori, the Tokyo 2020 President, welcomed the arrangement and said the firm's work would have a particular impact at the Paralympics.

"It gives me great pleasure to welcome Mitsubishi Electric as a Tokyo 2020 official partner," he said.

"By providing elevators, escalators and moving walkways, Mitsubishi Electric is making a significant contribution to the realisation of a barrier-free society and to promoting Para-sports.

"Shortly after the Tokyo 2020 Olympic and Paralympic Games, the company will be marking its centenary, and Tokyo 2020 is delighted to have such an illustrious partner on board."

The number of Tokyo 2020 partners now numbers 28, including 13 official partners.

"It will be a great honour for Mitsubishi Electric to contribute to the Tokyo 2020 Olympic and Paralympic Games as we head toward our centenary year in 2021," said Masaki Sakuyama, President and chief executive of Mitsubishi Electric Corporation.

"The whole company will be engaged in promoting sport toward the success of the Tokyo 2020 Games, and we would very much like to support the Games with Mitsubishi Electric elevators, escalators and moving walkways to facilitate the safe, secure and convenient movement of athletes and visitors alike.

"It is our earnest wish that the Tokyo 2020 Games will be a truly inspirational Games that bring people together and live long in the hearts and memories of all those who witness them."

The highest tier of domestic sponsors in Japan are the Gold Partners, which so far include companies including Canon, Asahi, NEC and Fujitsu.

A third tier of Official Supporters is also in operation.

Domestic partners are seen as key to the effective running of both Games, with the companies involved awarded the rights to use Olympic and Paralympic designations and imagery including emblems, mascots and slogans.
