Current use · 2000–2040Model estimates and surveys
Crude prevalence at ages 15 and older. Lines show posterior medians and bands show 95% credible intervals. Years after 2025 are forecasts. Survey dots use their reported age ranges and are coloured by survey type.

In 2025 is the probability that the target holds in that year. By 2025 is the probability that it held at least once from 2000 through 2025. Prevalence may subsequently rise above the threshold.

Probabilities for both sexes use prevalence weighted by the male and female populations. They describe the combined population, not separate attainment in each sex.
Difference between sexes · 2000–2040Any tobacco · percentage points
Men's prevalence minus women's prevalence for any tobacco in Japan, in percentage points. Positive values mean higher prevalence among men. Medians and 95% credible intervals are calculated from paired posterior draws.
Selected year · 2025Ages 15–100
Estimated prevalence in Japan in 2025, evaluated every five years of age from 15 to 100. Curves describe individual ages. Survey dots cover their reported age bands and years within five years of the selected year.
