Planning to move to Japan by next year June. I need advice on what else I can do right now

I am going to Japan for vacation this November. I will have a meeting with an immigration lawyer for my application as long term resident next year (third generation descendant)

• Is it possible to look for jobs now if i am moving next year?
• Any tips or questions I shouldn't forget to ask the lawyer about?
• any general advice on what i can do now to prepare?
