| Summary: | Background: Amidst the global coronavirus disease 2019 (COVID-19) pandemic, Japan has faced a significant public health challenge, evident from the significant increase in mortality rates since 2021. This study described the variations in all-cause and cause-specific changes in mortality up to 2022 in Japan. Methods: This study used official Vital Statistics from the Ministry of Health, Labour and Welfare (MHLW) to assess the impact of the pandemic on mortality trends. An analysis of all-cause and cause-specific age-standardized mortality rates (ASMRs) from 1995 to 2022 was conducted, employing the 2015 Japan Standard Population. Sex- and cause-specific ASMRs for a particular year were compared with those from the preceding year to assess annual changes. Results: Among men, the annual all-cause ASMR per 100,000 people increased from 1,356.3 in 2021 to 1,437.8 in 2022 (6.0% increase). Among women, the annual all-cause ASMR increased from 722.1 in 2021 to 785.8 in 2022 (6.5% increase). Compared with the period 2020 to 2021, COVID-19 (+29.1 per 100,000 people for men and +13.4 per 100,000 people for women), senility (+14.1 per 100,000 people for men and +12.5 per 100,000 people for women), heart disease, malignant neoplasms (for women) and “other causes not classified as major causes” substantially contributed to the increase in all-cause ASMR from 2021 to 2022. Conclusion: Further long-term monitoring from 2023 onwards is necessary, especially for conditions like senility, cardiovascular disease, and cancer, which may have long-term effects due to changes in healthcare settings, even though the strong countermeasures against COVID-19 were lifted in 2023. |
