Help with doubts about Japanese Bank Account

Hello everyone,

I am going to live next year for 1 year in Japan and dont plan to work there.

I want to rent an apartment and i have been told that getting a japanese bank account to deal with rent, services, etc will be very useful even if im not planning on working there, now the doubts i have are the following:
– One of my ideas is opening an account in JPost Bank when im there and using P2P in binance to transfer yen to that account, is this normal or safe? and if it is how much should i transfer so that it doesnt raise any strange alarms?
– I know that there are other banks that they say are better like Sony, should i close my bank account after 6 months and open another in Sony for example?
– How does JPost bank deal with international transfers, like transferring from payoneer or wise? i read that it may take quite some time and ask for a bunch of papers but maybe someone has more experience with this and can tell me.

Thanks for reading.
