During the ceremony, the students and attendants were required to wear a mask and keep a social distance in order to prevent the COVID-19 from spreading. However, after the graduation ceremony, some started taking off their masks just like before the the onset of the coronavirus endemic.
My wife and I are so happy to see my son chatting with his friends. This is my first time to see such a scene. I am very proud of you, Koba.
P.S.
This ceremony took place on March 18, 2020. The endemic has rapidly expanded, especially in European countries, followed by America, and become a pandemic with a skyrocketing number of the deceased from the virus infection. We are not under lockdown as of March 31, but seems to be scheduled. Super scared because nobody knows what would happen in Japan for the coming weeks and months.
