Welcome fellow Chinese
I think the best that they will offer is a work Visa for your husband. If you don't already possess a degree of some sort, it will be diffcult for you to find a job, BUT, I take that you are fluent in the 3 languages (Chinese - Mandarin or Cantonese? Deutch, English), so if you know Japanese too, you probably can be considered a skillful multilingual person that they can use you for, so that will MAY be sufficient for you to get a job with your secretary skills.
I would recommend renting a place, only because what is offered to you is probably going to be temporary, it wouldn't make any sense to purchase something there.
