I've been in Japan almost 15 years, and have PR status. As my Japanese partner and I plan to be together long-term, I've been trying to find out the legal/financial implications of marriage. For us to live overseas, as we plan to do sometime, being married would certainly make things easier. But I am wondering about the implications in Japan. We currently live separately, her with her two teenage kids in the countryside and me in central Tokyo. Would there be any new financial obligations I would face - taxes, pensions, healthcare, etc? She currently receives benefits as a low income earner and single mother - would she lose these? (Her ex has never provided any support in over 10 years). Would I be legally obliged to provide for her kids and responsible for them, their education, etc. if she were incapacitated or died? We plan to be together in any case, but simply wondering if marriage would make things easier or more difficult. Thanks in advance for any helpful information.
