leprosarium; leper colony
Medical term for a facility where people with leprosy (Hansen's disease) were treated or isolated. Historically used, but now often replaced by more modern terms like ハンセン病療養所.
There used to be many leprosariums in Japan.
The leprosarium in this area is now preserved as a museum.
More modern and preferred term for a leprosy sanatorium, using the disease name 'Hansen's disease' instead of the older, stigmatized term.
Compound of 癩 (rai, 'leprosy') + 療養所 (ryōyōjo, 'sanatorium'). The term reflects historical medical terminology.
