It gives me great pleasure to publish “Technology and Innovation in the Olympic and Paralympic Games Tokyo 2020”
In the face of the “Coronavirus Disaster” which no one could have predicted and against the backdrop of
unprecedented and difficult headwinds in the history of the Olympic Games that even the holding of the Games was injeopardy the original vision of the Games as “the most innovative Games in history bringing positive change to theworld” has been transformed from a goal to be achieved to a challenge to be met and without the realization of thisvision the convention would not be a successIn such an environment all the engineers have demonstrated their personal best with their advanced project
management skills and responsiveness even in an unusual environment and under unexpected conditions Furthermore
I would like to share with you the trajectories : the trajectory in which researchers from various fields harmonized theirbest technical capabilities toward a single goal the trajectory breaking down the barriers between industry
government and academia the trajectory of creating and passing on legacy experiences to the children of today whowill be at the centre of creating the next Tokyo Olympics in decades to come Following the basic concepts of the Games
these trajectories of top‑class researchers and engineers who have surprised the world with their innovations for thefuture are packed into this magazine
We would like to contribute to the further development of ICT technology in the future by documenting this great
success story as an asset disseminating it globally and passing it on to future generations
In closing I would like to express my appreciation and respect for the efforts of all those involved in the medical field
whose efforts cannot be fully conveyed in this journal and the many researchers and engineers who have supported(and continue to support) them with ICT technology

Due to the coronavirus pandemic an unusual decision was taken to postpone the Olympic and Paralympic GamesTokyo 2020 for one year and we needed to concentrate on ensuring that at the very least the competitions themselves
could be run safely We regret that we were forced to hold the Games with almost no spectators and not able toSpecial Issue : Technology and Innovation in the Olympic and Paralympic Games Tokyo 2020©2022 IEICE

complete our attempts at innovation projects using digital technology as we had originally envisioned However becauseof the difficulties we faced we devised unprecedented solutions which contributed to the execution of the Games I am
proud of thisA rulebook was developed to protect the athletes and stakeholders of the Games from the virus infection Accordinglya management system for information sharing was essential to securely implement the rulebook We also introduced anenvironment on a trial basis that allows spectators to enjoy a more realistic experience online or virtually participate in
the frenzy We believe that we have used the Games held at the coronavirus pandemic as an opportunity to develop theseitems which will be utilized in the future
On the other hand ensuring cyber security was undoubtedly a mission of a higher priority than ever before and its
realization was also extremely difficult in line with the growing complexity of the Games operations Looking back on theGames the keys to success were for example how reasonably we could anticipate and estimate possible cyber‑attacks
and how flexibly we could prepare risk control measures in the event of “Outbreak” Among these things I would like tomention that the repetition of on‑the‑job training prior to the Games to master the prepared cyber security functions
was a major key to the success in fact
I hope that this special issue will help you in your future social activities as one of the records of having completed thehistorical event

In September 2021 the Olympic and Paralympic Games Tokyo 2020 which had been postponed by one year due to thespread of the coronavirus disease 2019 (COVID‑19) were successfully completed I would like to express my deep
respect for the efforts of the Organising Committee and everyone involved in the Games which enabled the event to be
successfully completed without any major problems
It is no exaggeration to say that operation of such a large sports‑event and associated video distribution to the world
would not be possible without the proper use of a variety of wireless systems these days In particular since the Gameswas held in Tokyo a city with overcrowded spectrum use there used to be concerns at the outset as to whether thenecessary radio frequencies could really be secured
In cooperation with the Organising Committee and local radio station licensees MIC had worked to secure thenecessary frequencies and to tackle a variety of tasks including spectrum management inspections of wirelessequipment brought in and spectrum monitoring This contributed on the success of the Games through an appropriate
and without interference and jamming use of a variety of radio systems
Unfortunately we were not able to welcome many guests from overseas to Japan to watch the Games in person at thevenues Nevertheless VoiceTra a multilingual voice translation technology developed primarily by the National
Institute of Information and Communications Technology (NICT) was used for smooth communication of necessary
information at the competition venues
The various experiences and technology developments regarding spectrum management left behind by the Games
will be an asset valuable for the future Then it is important to summarize the event and pass the knowledge on to thenext generation
We hope that this special issue will help build a bridge to such future

While the Olympic and Paralympic Games Tokyo 2020 (hereinafter referred to as “Tokyo 2020 Games”) were held
without spectators more than 3 billion people around the world watched the Games on TV and online Accordingly
cyber security was a major issue for the Tokyo 2020 Games Then the Organising Committee the private sectors andthe government worked together to prepare for and respond to this issue
One of the governmentʼs representative activities was the establishment and operation of the Japan Information
Sharing Platform (JISP) to facilitate the prompt and efficient sharing of threat information among the approximately 350
organizations involved During the Games we shared information regarding malicious websites promptly and called forfull caution As a result of these efforts no cyber‑attacks that could have affected the operation of the Games wereobserved
It is important to link these activities for the future and utilize the findings It is necessary to share the know‑how
gained through the Tokyo 2020 Games with other countries who are planning to host the Olympics etc as well as toutilize the approach toward the Tokyo 2020 Games for raising the overall level of cyber security preparedness of ourcountry
The Tokyo 2020 Games was probably the first case of such close collaboration that Japanʼs public and private sectors
worked together to ensure the cyber security of the event which attracted global attention We hope that this report will
help to widely share the awareness that cyberspace is a public space that should be protected and nurtured by everyone
and to build and spread the cooperative and interactive models of different entities for ensuring cybersecurity
I hope that this special issue will provide you with hints for strengthening your cyber security measures㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇㍇Special Issue : Technology and Innovation in the Olympic and Paralympic Games Tokyo 2020©2022 IEICE5
