Japan had the highest rate of mRNA vaccination per capita in the world and in 2022 and 2023 excess deaths per 100,000 were 1,400 above baseline in that country. That was 3x higher than the United States, which also had historically unprecedented high rates of excess deaths too.

1,400 deaths per 100,000 citizens above baseline means Japan had approximately 1,736,000 excess deaths per year in 2022 and 2023. This is literally unheard of and nothing close has ever happened in modern peacetime history.
