Paying taxes with remote work overseas – tax accountant recommendation?

Hello,

from October I will start working remotely for an overseas company.
The way I will receive my salary is basically this: I create an invoice every month, submit it to my company, my company pays the gross amount in Euro to my bank in my country. It is then my responsibility to pay taxes to Japan on that amount.

I’ve read here many times how important it is to pay taxes correctly and on time. Since I don’t trust myself to navigate the Japanese tax system, as I barely can in my home country; I was thinking that a tax accountant would be useful in this case, but I have no idea how to find a good one that speaks English and is familiar on handling this kind of situation.

Does anyone have a recommendation? Or if you do without external help, how difficult is it?

Thanks.
