The asthma mortality rate in Japan has remained stable at 1.0 deaths per hundred thousand persons in 2024 and 2025, with a forecasted slight decline to 0.9 over 2026 to 2028. This represents a minimal year-on-year change of around -10% starting from 2026, compared to the stable rates of the previous years. In 2023, the asthma mortality rate was similar, at 1.0. The five-year compound annual growth rate suggests a modest decline as well.
Future trends to watch for include advances in asthma treatment options, improved air quality policies, and public awareness campaigns that could further reduce mortality rates. Monitoring these trends will provide insights into the effectiveness of healthcare systems in managing asthma in Japan.
