It is my pleasure to announce that the 22nd International Congress of Nutrition (ICN) will be held in Tokyo, Japan, in September of 2021. ICN is the four-yearly meeting of the International Union of Nutritional Sciences (IUNS), the tenth of which was successfully held in Kyoto in 1975. Tokyo was selected as the host of IUNS-ICN2021 at the general assembly meeting of IUNS held during the 20th ICN in Granada, Spain.

Tokyo is the most innovative city in the world, boasting outstanding infrastructure, convenience, cleanliness, and safety. The Tokyo International Forum, the planned venue, is a state-of-the art facility located in the center of the city. As Chair of the Organizing Committee for the 22nd IUNS-ICN I can assure you that you will benefit not only from the great scientific achievements of the congress itself, but also from unique experiences of Japanese culture, history and various other entertainments. The secrets and appeal of the Japanese diet will of course also be of interest to the participants in the congress.

The world is faced with a variety of nutrition-related issues, including food shortages, malnutrition, population growth, over-nutrition, diversification of dietary habits, threats to food safety, and the aging of society. Japan has tackled all these issues over a relatively short period of time and has devised various methods to resolve them, thanks to the ingenuity and flexibility of the people of Japan.

The population of our planet is forecast to expand to 10 billion during this century. Nutrition has the power to provide health and happiness to people living today and to future generations as we head towards the 22nd century. Accordingly, we have chosen as the theme of the congress, “The Power of Nutrition: For the Smiles of 10 Billion People.” We hope that by bringing all of you from around the world together in Tokyo in 2021 we can engage in valuable discussions on nutritional issues. The congress will be an ideal opportunity for participants to reaffirm or rediscover their mission to help to realize good health and happiness for future generations.

I look forward to welcoming you at the 22nd IUNS-ICN in Tokyo in 2021.

Significance of ICN Being Held in Japan

Japan suffered from and overcame severe starvation in the aftermath of World War II, but soon after it faced new issues derived from overnutrition. As such, Japanese people have always had strong concern about both of those problems that are expanding worldwide. Japan is proud of its unique position in basic and applied research on nutrition as well as in nutritional practices and policy-making.
One of the bases for that pride is the Japanese population having the longest longevity of anyplace in the world, to which Japanese traditional dietary practices and ongoing efforts of researchers and dietitians have surely contributed much. Another contribution to that health may be the excellent school lunch system of Japan, which played a major role in the improvement of people’s nutritional status. Japan is also known as a home to the concept of functional food for health. That concept and its practical use in Japan have cast light on new possibilities of foods.
Factors important for the success of the congress go beyond just the academic background described above. The Japanese government, industry, and other organizations around the world have expressed the will to strongly support us. They will help gather a large number of young researchers and participants from developing countries. Finally, the most important factor for success is Japanese scientists who are prepared for and devoted to the success of ICN 2021 in Japan.
