The nation-wide state of emergency was lifted in Japan, and today is the first Sunday as a normal day-off. Many people go out and enjoy the whole day. Meanwhile, scientists discuss the present situation, which is really strange. The number of cases goes down, while many people go out day by day. They worry about the situation that is a kind of transition phase from the Delta variant to another type of variation. Thus, we are in the middle of tranquility before chaos. Anyway, who not enjoy Sunday?; it is the Day of our Lord!
