Japan is right now at this time undergoing a massive surge in COVID with both cases and deaths at peaks matching or higher than anything that came before now.
It's unclear if it's peaked yet, it may be at the peak right now but it's hard to tell from charts....
It's a massive BA.5 wave, it shows up on the normal stats sites and is mentioned in the world news, here's a little link that mentions the current 7th wave in Japan :

So they may have relaxed things a little but be prepared for the unexpected as it is a rapidly developing situation over there and it's happening right now.
Lets hope this is not an indication of things to come elsewhere as it's not looking so great over there....
