Back to school!

Kind of.
Cian went back to his school this morning for the first time in nearly two weeks. He was there for all of 35 minutes before he (and his classmates) were hastily ushered out and told not to darken the school doorways again until early April.
Ostensibly, Cian and the other 79 students in first year, were in school so that their teachers could check on their well being, offer 'guidance' on their home studies, and ensure that students were taking the necessary precautions against the coronavirus.
In practice, it was a PR exercise, one repeated in many schools across Hokkaido all this week. Since the governor of Hokkaido declared his state of emergency and 'requested' the schools be closed, he has come in for sustained criticism about 'over-reacting'. That and for not providing an answer to the question of 'what parents are supposed to do with bored kids forced to stay at home all day?' (As an aside, it is an interesting insight into Japanese culture that politicians [the governor] and the formal education system [schools] are expected to answer that question rather than the parents themselves.)
To counter this criticism, the Hokkaido Board of Education mandated a system of 分散登校 (bunsan toko), 'dispersed school attendance'. According to this initiative/ public relations stunt, students go to school once a week for a maximum of 60 minutes so that their teachers can, well, I don't know, remember who they are? Remind them not to congregate in large groups in small areas like restaurants, and playgorunds, and schools, and, eh, hang on a moment...
This being Japan, there was also a lot of fine detail involved in order to give the appearance of specific concrete measures being taken. Hence, students in each grade would come at different times during the day; students would be not be allowed into their classrooms, but rather would have to assemble in the school gym, sitting exactly 2 metres apart (front and back, left and right) from each other; masks to be worn; not to mingle with their classmates; and following the dispersion of each batch of students, the teachers would then frantically scrub clean and disinfect the entire school (Sanae had to this 6 times in her school yesterday).
Like I said, a PR exercise so that the prefectural governor and Board of Education can demonstrate  that they are taking specific (albeit completely futile) actions for the well-being of the island's students.
