Japanese place names are retained when no verified English name is available.

Children, families and related measures

This group brings together measures with different definitions and source periods. A listed specialty or facility record is not evidence of service quality, capacity, availability or access.

This measure reports the source-published capacity as of 1 April 2025. It does not show vacancies or places currently available. Figures published only for a designated city are not allocated to its wards. Where no ward-level figure is verified, no figure is shown; this does not mean zero.

Browse another municipality. Each municipality profile provides its own source details; comparison does not create a combined score or rank.

  • Values are descriptive statistics based on the same published facility snapshot.
  • Facilities with unknown bed counts are excluded from bed mean, median and distribution summaries; missing bed counts are not treated as zero.
  • Numeric differences describe facility composition. They do not indicate healthcare quality, capacity, access, need, adequacy, superiority or rank.
  • Population-denominated measures use the Basic Resident Register reference date as descriptive context; they do not measure need, access, quality, adequacy or superiority.
  • When a municipality has a zero population denominator, rates per 100,000 residents are not displayed, to avoid division by zero.

Sources and reference periods

Source titles and official records may be in Japanese. Dates and geographic units are shown separately for each source.
