The Tokyo Olympic Village Main Cafeteria is a 24-hour cafeteria that has 3,000 seats and can serve up to 45,000 meals per day,*** with more than 700 types of food, but does not mark the origin of ingredients.

There is also a casual dining restaurant that serves casual food such as rice balls, spreads and light meals. With 280 seats, it can serve up to 3,000 meals a day. All Japanese domestic ingredients are used, and the place of origin is labeled by city, town and village.

The Tokyo News reported on July 18 that the main cafeteria in the Tokyo Olympics Athletes' Village gave up publicizing Fukushima ingredients in consideration of "protests from a portion of the country," and replaced it with a cafeteria that does not mark the origin of all ingredients. Another cafeteria will mark the origin of ingredients by city, town and village, but will not introduce Fukushima ingredients individually.

Korean delegation decides to give Korean athletes their own boxed lunches:

The Japanese government had planned to use this Tokyo Olympics to publicize the safety of Fukushima food, but it was protested by some countries. A source from the organizing committee revealed that it had wanted to further publicize the revival (of Fukushima), but some countries were reluctant to eat Fukushima-produced food, citing radioactive substances.

The South Korean newspaper Joongang Ilbo reported on June 29 that the organizing committee of the Tokyo Olympics and Paralympics announced that it would use specialties from 47 prefectures across Japan to supply ingredients for the restaurants in the athletes' village, and that Fukushima halibut also appeared on the shortlist.

In response, the South Korean delegation said it had decided to strictly monitor the food ingredients provided in the Athletes' Village in order to ensure the safety of the athletes' diets and decided to give the South Korean athletes their own boxed lunches.
