The break down by area for the 7th has still not been updated on the Saitama Covid website.

September 7th

*I initially reported 15 from my trusted source. However, at 9 pm the Prefecture reported the overall total as 14 not 15. The discrepancy is coming from Koshigaya’s figures which news agencies and subsequently the prefecture reported as 2 new cases. However, Koshigaya reported it as 3 on Twitter and their official site. 1 of the 3 is from an earlier date; perhaps why it wasn’t counted? Whether the additional case will be added retrospectively or not remains to be seen.

We will only know for sure at 9 pm tonight when Saitama Prefecture make the final and official announcement. Also, Kawaguchi and Kawagoe have yet to announce. It is not unusual for Kawagoe to have zero cases, but it would be unusual for Kawaguchi.

17:07 ~ Saitama Prefecture announced 10 new cases of Covid-19. One death was also announced in the prefecture today, a man in his sixties.

17:01 ~ Koshigaya announced 3 new cases of Covid-19. Some sources are saying two only, but the Koshigaya City official site has listed three: a woman in her forties, a man in his fifties and a man in his sixties.

  1. still there doesnt seem to be massive spikes like we’ve had here. Thankfully it seems to be settling down in Victoria right now, fingers crossed!

    1. I really hope you can keep it that way. They’re opening up International travel here next month, slowly but surely. I’m so nervous that a stronger strain will make its way into Japan.
