American with Japanese wife. How do I get a job in Japan?

Night business would be easiest one. It is profitable, too. Spouse visa assures you any job except illegal.

Marry American woman.

Your best option is getting a job instructing English. Since you already have a spouse visa, you don't have to worry about all the working visa stuff (having a bachelors etc). Many companies actively seek people who already have visas so they do not have to sponsor visas. Check out gaijinpot for job listings: https://jobs.gaijinpot.com/ Also try out: http://www.jobsinjapan.com/ Once you get into Japan, and get your alien registration done, I think you'll be ok finding either part-time work or even full time in the English instruction world. You might pick up a string of part-time jobs.

Your situation is very hard in Japan. No college degree, no skill or experience (Tell us if you have some). You do not speak Japanese. And Japan is in the middle of worst recession since WW2. >So if anyone can help, how do I get a job there in my situation? Do not expect anyone to help you find a job in Japan. Everyone is struggling hard to survive himself.

No college degree? LOL! According to Japanese society, you're a loser and burden. I would say make the best out of your life here, but Japanese women do get homesick and will run out on you. This is tough man!!!! Get a degree and get a job as an English teacher. But seriously, this is really bad if she wants to live there and you can't go. Japanese women will leave you and u'll get entagled by the law. It happens all of the time. I do agree with others about how u should have married an American women. This is really a mess...I'm not sure if you see how big of a problem this can and will be. Not many Japanese women in America because not many want to stay here. The only ones that stay here are the ones who were here from before WW2.

I'm seconding pretty much everything Tokyo E said, but I'd also like to add that with the spouse visa, employers may look at you a little more seriously as a long term employee, not someone who just wants to experience Japan for a year then split. I only had one year of part time teaching experience before I got my current job, and I'm about halfway though my 5th year there (full time English instructor at a small kindergarten). And one of the reasons they picked me is because they wanted someone for a long term.

You could teach English yourself, freelance. Just run some ads in local magazines and startup your own independent English lessons which you teach at cafes. I know Japanese people who teach English that way and they make enough money to pay the rent. You have to be a hustler, though. If you are doing it freelance, you always have to make sure you have enough students to pay the bills. Another options, which seems to work for some foreign guys, is just to let your Japanese wife work while you sit around and play video games all day. (J/K, don't get angry.) Another option, depending on your skills, is to do other types of freelance work, like on Elance or Odesk. Those sites are good for anyone who wants to do freelance work and make money online. But, you need to have some kind of skill, like programming, design, data entry, translation, etc. Good luck!
