Notification Regarding Overseas Travel
The number of cases of infection with the novel coronavirus COVID-19 is increasing throughout theworld, and the World Health Organization has characterized the situation as a global pandemic. In light ofthis rapidly evolving situation, all students, faculty, and staff are asked to refrain from all overseas travel
for the time being.
Faculty and researchers who have already received approval from the Graduate School or the university
for sabbaticals or projects to be conducted overseas are asked to reconsider carefully whether those trips
are really necessary, especially after weighing the risks that might arise under these quickly changing
conditions and the fact that they would have to take responsibility for those risks themselves.
If a faculty member decides to delay his or her sabbatical period and the necessary adjustments can bemade by the affiliated departments, then the Graduate School and College will respond flexibly.
Furthermore, faculty members who are planning future sabbaticals may proceed with the procedures forrequesting sabbaticals within their departments.
Precautions related to the COVID-19 outbreak are summarized below. Please continue to monitor thelatest information and to manage your health and safety carefully.
