I don't know how much gene-sequencing Japan conducts. A new variant is suspected by some commentators. Another cause of a surge in Japan in general could be this, as quoted in post 2,991: "a 4.73-fold rapid increase in just over a month since immediately after the status of COVID-19 was downgraded to “category 5,”."
In the Nordics, we saw what happened when the pandemic when all restrictions, even masking, were abandoned and the pandemic was downgraded in the winter of 2021-22, post-vaccinations:
Cumulative confirmed COVID-19 deaths per million people (Dec 1, 2021 --> present)
Look at Finland, Iceland and Norway, in particular:
Cumulative confirmed COVID-19 deaths per million people (Dec 1, 2021 --> present)
The graph looks as if the pandemic had only just begun in the fall of 2021!
I don't know if the Japanese have the same degree of trust in their (health) authorities as people in the Nordic countries, but the downgrading of COVID-19's status is probably mentioned by news sources because an impact is suspected.
