Background

Kusatsu Special Prison was a prison that operated between 1938 and 1947, in Kuryu Rakusen-en Sanatorium in Kusatsu Onsen, Kusatsu town, Gunma Prefecture, Japan, where criminals from public leprosaria throughout Japan were imprisoned. Prisons for conventional crimes had been built earlier in all public leprosaria. A total of 22 out of 93 prisoners died of cold or maltreatment in the cells or after confinement. In Japanese, it was called Tokubetsu Byoshitsu (特別病室, Special Ward) or Jyu Kanbo (重監房, Prison for Severe Crimes).
