Tokyo, 23 January 2020
– The Tokyo Organising Committee of the Olympic and Paralympic Games
(Tokyo 2020) today unveiled the uniforms that will be worn by technical officials at the Olympic and
Paralympic Games Tokyo 2020. Technical officials will ensure that the rules and regulations of each sport
are observed during events, and will make judgments on rule infringements, performances, times and
rankings. Their uniforms have been designed in line with Tokyo 2020’s guiding principles of “Sustainability
and Diversity”, as well as to counteract heat. Formal and casual versions will be provided, and individual
sport federations will decide when their respective technical officials should use each.
The formal wear has been designed on a gender-neutral basis with unisex jackets and slacks and no skirts. It has also been designed to suit all nationalities, ages and working environments, and officials will be able to select either ties or scarves as accessories. Jacket linings, ties and scarves feature the colour kurenai, a traditional Japanese tone and one of the Tokyo 2020 core graphic colours. Elements of the Tokyo 2020 emblem, expressing the Games’ value of unity and diversity, feature throughout the uniforms.
While featuring a different colour, the design of the technical officials’ casual wear is the same as that of the Field Cast volunteers’ uniform, emphasising the unity of purpose between them. The jackets can easily be removed and different lengths of trousers worn, allowing wearers to quickly adjust their attire in accordance with the weather and temperature.
The formal wear was designed by AOKI Holdings, one of Japan’s leading producers of formal wear; the
casual wear was created by ASICS Corporation, who have extensive experience in providing kits and
uniforms for athletes and teams.
Both the formal and casual uniforms incorporate features to protect against heat; their material has
superior breathability, excellent moisture-absorbing properties and is quick-drying, making them more
comfortable to wear and easy to move around in during the Japanese summer. They also use stretch
material to enhance mobility and comfort, and are machine washable.
Reflecting Tokyo 2020’s focus on sustainability, some plant materials were used in the composition of the
uniforms’ fibres, and their manufacturing process took account of the need to avoid environmental
In line with Tokyo 2020’s promotion of the concept of “unity in diversity”, the uniforms feature a unisex
design and comfortable materials that will allow officials of all ages, nationalities and genders to wear
them comfortably. A wide range of sizes will also be offered.
Development and manufacture of the technical officials’ uniforms was supported by donations from the
sale of Tokyo 2020 New Year’s postcards in 2019.
