Moving to Japan on a tokutei visa with a dependent

Hello Redditors,

I'm planning to work in Japan in 2026 (I know it's still a while away). I'm currently in Myanmar, which is a country with travel restrictions. My main question is, what kind of work would be feasible for me?

Since I don't have much professional experience, getting a standard work visa seems impossible. I believe my only option is a Specified Skilled Worker (Tokutei Ginou) visa.

We are planning to get married, which would allow her to apply for a dependent visa and join me in Japan about three months after I arrive. I'm trying to figure out the estimated monthly living costs for two people. I haven't picked a city or a job yet, but I plan to live in a cheaper area and possibly work two jobs if allowed.

So, my questions are:

1. How much money would a couple need per month to live frugally in a less expensive city?
2. Is there anything else I should be considering, especially regarding the dependent visa process?
3. My girlfriend won't be able to work for at least the first six months while she learns Japanese. How will this affect our finances?

Thanks for answering!!
