What does the eight rounds of epidemic in Japan mean?

Eight rounds of epidemic in Japan means that Japan has experienced eight epidemic peaks. The first epidemic peak in Japan was from March to May in 2020, and the prevention and control policy was relaxed at the end of May. The second peak came in the next two months, gradually dissipated with the arrival of summer, and the third peak began to appear after entering winter. With the flow of people at the end of the year, this peak lasted until March, 202 1. Within a month, Japan entered the fourth and fifth peak periods, which appeared one after another, and eased on September 202 1. Six months after the sixth peak, Japan decided to liberalize its prevention and control policy. With the liberalization of prevention and control policies, transnational personnel flow has also brought more viruses, and the seventh peak has appeared since then. In June, 2022, 165438+ 10, Japan also ushered in the eighth round of peak period, which has continued to this day.
