Highlights

• The 2015 Japan Standard Population (JSP) was established in response to changes in the age structure.
• We investigated the impact of the change in the 2015 JSP from the 1985 JSP using the best available data for population and number of deaths.
• The effect of the introduction of the 2015 JSP on interpreting trends in the all-cause mortality rate was minimal.
• Caution is needed when interpreting trends in some cause-specific mortality rates, namely those for malignant neoplasms and pneumonia/bronchitis.
• We archived all-cause and leading cause-specific age-standardized mortality rates calculated using the 2015 JSP from 1950 to 2020.
