As of 2023, asthma mortality among males in Japan was recorded at approximately 550 deaths. The forecast from 2024 to 2028 shows a slight decline in male asthma mortality with values decreasing incrementally by a few deaths each year. Year-on-year percentage variations indicate a steady negative trend, reflecting improved healthcare measures and possibly better asthma management. This decline can be quantified by a Compound Annual Growth Rate (CAGR) showing a steady improvement in survival rates over these years.

Future trends to watch for include:

Continuation of advancements in asthma treatment and management.
Impact of environmental policies on asthma prevalence.
Effectiveness of public health campaigns in raising awareness about asthma management.
