Move to Japan

I will move to Japan in the next months, but I have many doubts about this. How to move all my staffs, clothes etc...? I think 2 baggages in the plane are not enough (I am considering to add 1 or 2 baggages at the moment I will buy the ticket, is this a stupid idea?). And should I tranfer all the money I have in my bank account in the new japanese account? Or transfer like 70%-30%?
There are so many things to think about, so for any suggestion or experience I will be grateful.

It would help to know whether your moving temporarily and for how long, or permanently. The approach might be different for each case.

However, I would always recommend to go lean on the baggage. Bring only what you think it's truly needed, then most other things you can get here anyway.

Are you really "moving," or just traveling extensively? If you mean somewhat long-term, do you have your visa issue sorted out? Any employer or school program?

About baggage, most airlines would charge you extra for bringing in more than the baggage allowance, so you should be careful. It sounds like you are still outside Japan, but do you already have a bank account in Japan?

you need to give full details then people can answer your question properly.
are you moving for WORK or for further studies ETC?
how long is your visa?
which city are you moving to?
then we can know the minimum and maximum amount need to cover your expenses .
