What do you call orphanage in Japan?

Hello there, sorry if my question is confusing.

For context, most orphanages in the US/America were replaced or renamed as Children's Homes, Group Homes, or Foster Care (although each of them has different systems of children's housing). I'm just curious if that was also the same case in Japan— or are they still called "Orphanage"?

The same thing happened in Japan. An early 20th century law stated it as "ko-ji-in" which literally translates to "orphan-age", but the law changed to have it called "yougo-shisetsu" and then to "jidou-yougo-shisetsu" which literally means something like "children's care facility". By the way, colloquially, people just call it "shisetsu" which means "facility". The expression "shisetsu" is used for facilities of any kind, so you need context to clarify the meaning, unless you use the whole word which is "jidou-yougo-shisetsu".

言葉狩り, word hunting, occurs everywhere meaninglessly. as same as your country.

養護,yougo, does not have the meaning of orphan. it means "need cares (specially)".
so that, 養護学校 meant schools for special cared students (for handicapped youngers). now, they changed 養護学校 to （特別）支援学校, (specially) supporting school, schools for youngers who need to have special supports.

everything is so stupid.
