I apologize for bumping this topic, but I actually have a question and didn't want to start a whole new thread just to ask it.

Now, as it's been pointed out long ago, literal orphans are kind of a rarity. I was wondering where would someone go to adopt (and I don't mean internationally)? Are there orphanages in places like Nerima-ku? Are orphanages mostly just dealt through churches? If someone lived in Nerima-ku in one of the wards, would there likely be an orphanage in that ward, or since this is Kanto, it'd probably be in Tokyo or something? I tried doing a search online, but couldn't come up with much. I'm curious where some orphanages are in Japan. No, I'm not adopting...this is purely for research purposes.
