This came up couple of times when i was reading yaoi
basically, a seme adopting the uke (who i suppose are year or two younger than him) serving as a kind of "gay marriage" i suppose?

I get that gay marriage is illigal in japan, and the lovely couple wanted the inheritance right and insurances and stuff cleared up. and i suppose adoption does fix that issue.

but i see 2 problems...

1. can you even adopt someone that's younger than you by 2 years? 😐
2. it means you're having sex with your adopted son. I know, it's a different case. the adoption is just for the paper. but man you can get some serious trouble with that maybe? (wait its consensual, so if the adult son consent to sex with his father its ok i suppose?)

so...i kind of have hard time believing this is actually practiced in japan
is this all a far-fetched myth?

Meh, Id say that would have a better chance in running away together to Canada( uh, might need to buy a translator XD) or some place that has gay marriage legal and fairly common. I kind of do think that it sounds a bit weird to be lovers with an adopted son, but I ve seen many, MANY weirder scenarios.
Some people even have relationships that nobody else knows of, even in real life. I guess when it comes down to it, nobody else can really TELL a person who to be in a relationship with, since its everybodys own business. As long as one of them is not being forced by the other.
Im not actually sure whether you re looking for a manga or just asking in general. 😎

1. Yes. In Japan, adult adoption (which is different than adopting a child) can occur as long the adoptee is at least one day younger than the adopter. So a man could adopt someone the same age as long as they don't share the same birthday.

2. The main purpose of adult adoption is to create an heir for a family and/or business. It is a totally different scenario than raising a child as your son. On paper the adoptee would be legally your "son" (as in heir) but since they are an adult I doubt there would be the same kinds of "trouble" like there would be if a "parent" molested his child. (Besides, if two adults adopt as a form of "marriage" then they wouldn't see each other as "father and son" so I doubt either one would make a complaint. They are getting "married" because they want to be together like spouses)

I don't know if any gay men in Japan actually resort to adult adoption as a way around gay marriage or not. But I've read about in dozens of BL stories. Which leads me to believe that someone must have at least considered it be plausible.

These are a couple of articles about adult adoption in Japan, although neither mentions using it as a loophole around gay marriage.

lol
But before we start saying "only in Japan..." adult adoption and adoption between same sex couples also occurs in the U.S.
