... The issue here is that the AZ vaccine is, in general, less effective than the MRNA ones, so once MRNA supplies are sufficient, AZ is generally abandoned. Japan is behind the curve here; most developed countries stopped using AZ in mid to late 2021 (except in cases where people are allergic to an ingredient common to both MRNA vaccines).
Anyone getting a vaccine in Japan today is probably getting a booster, and AZ can't be used for that anyway.
There's no crime, against humanity or otherwise, here; AZ works less well, so has largely become obsolete.
