At a June 23 meeting, the health ministry's coronavirus expert advisory board said that COVID 19 case numbers across Japan are continuing to fall, but the rate of decline is beginning to slow down. The board said that a rise in cases isn't expected for big cities in the short term. The board said that the number of infections may increase due to the weakening effect of the third booster shots, and that people are expected to make more close contact during the summer vacation.
The ministry said the number of new COVID 19 cases in Japan was 0.98 times that of the previous week. The cases are declining in all age groups. There are signs of a resurgence in some areas. The number of infections was 1.09 times that of the previous week in Tokyo and neighboring Saitama Prefecture, 1.08 times in Chiba Prefecture and 1.12 times in Kanagawa Prefecture.
