As of 2023, Japan's BCG immunization coverage among children aged 1 year old stood at 95%. Forecasted data from 2024 to 2028 indicates a steady coverage rate of 96%, with a slight increase to 97% in 2028. This reflects a stable trend with minimal year-on-year variation in coverage under 2%, highlighting Japan's consistent public health efforts to maintain high vaccination rates. The compound annual growth rate (CAGR) is expected to be positive yet modest over the next five years, suggesting sustained commitment.
Future trends to watch for include demographic shifts that could impact immunization logistics and potential revisions in national vaccination policy, especially if new health priorities emerge.
