Thanks Nyorin, ozkai. Leading on from those answers, I would assume that it would be difficult a 17 year old without a highschool diploma, a degree, fluency in Japanese, work experience or savings to marry and support a wife? I suppose if the OP's girlfriend is working she could support him while he takes on a more domestic role, but that tends to be frowned upon in Western society and it looks like Japanese take a similar view. How difficult would it be for a foreigner with a spousal visa to find the kind of work that doesn't require a degree or Japanese skills?

I'm not saying it's impossible or that people need to stick to traditional gender roles, but it's important to keep in mind that going against the grain and financial issues can put a lot of stress on a relationship.
