COVID-19 Precautions and Other Important Matters
for Komaba I Campus During Summer Vacation
Thank you all for your continued cooperation with the countermeasures against
COVID infections.
Due to the resurgence of COVID-19 infections, the number of people infected atUTokyo has been on the rise. The causes of infection include eating, drinking, andcongregating in large groups, infection from roommates, and infection at overseas
locations.
During the summer vacation, after the regular examinations have ended, allundergraduate and graduate students are advised to continue to refrain from eating anddrinking in large groups.
While extracurricular activities remain very important for you, they must be
conducted in accordance with the following university-wide guidelines on
extracurricular activities during Level A; that level corresponds to Stage Yellow I on theKomaba I Campus, so please refer to those guidelines as well. In any case, please takeall necessary precautions to prevent infections, including before and after yourextracurricular activities, so as not to create clusters.

To keep COVID-19 infections from spreading again, it is important to continue
implementing existing infection control measures thoroughly. Please continue to usemasks, hand sanitizers, and social distancing when in crowded places or when nearelderly people, and avoid eating, drinking, and socializing in environments wheredroplets and contact are likely to occur. In addition, please actively consider getting
vaccinated at a medical institution and being tested to ensure more complete control ofyour physical condition.
Precautions against heat are also necessary. While remaining careful to avoid thespread of droplets, take appropriate measures to replenish fluids and salt. Engage inactivities that are appropriate for the current temperature, while removing and putting

In addition to preventing infections, students who have reached drinking age areurged to maintain moderation in their behavior, as alcohol consumption may havenegative effects on health. Please do not engage in dangerous or illegal activities that
could lead to life-threatening accidents, such as pressuring others to drink alcohol ordrinking alcohol yourself if you are under the age of 20.
In addition, please be mindful to comply with laws, regulations, and social norms. Do
not say or do anything inappropriate on the Internet or in any media, do not possess oruse illegal or dangerous drugs (including law-evading herbs), and do not commit anyother criminal acts such as harassment, sex crimes, or fraud.
As you know from recent news reports, you should also be aware of cult groups andunscrupulous business practices. Students with little social experience are particularlylikely to be targeted by cults and fraudsters. Be very cautious about revealing personal
information about yourself, and take appropriate actions such as refusing or ignoring
people who seem suspicious.
Keeping in mind the general student population of UTokyo, we offer advice about
appropriate student life and what to keep in mind in your daily life on university
websites and in the booklet “Hongo Student Life 2022” (in Japanese). Please refer to thefollowing URL for precautions about student life; this site includes information on
following rules, drinking, drug abuse, information ethics and SNS, research ethics,
harassment, cults and suspicious persons, consumer problems, and other important
issues.
