How can a foreigner do a house loan?

Greetings I am an Europan living in Japan.

I work remotely from Japan. My company is European, my contract is European, my bank is European.
I wanted to buy a house in Japan so I contacted a financial company but they told me that in order to have a loan I must speak Japanese fluently (not my case, will take years for me), have a full time contract in Japan for at least one year (I have no plan to leave my company, especially to join a Japanese one).

My bank says that probably they cannot start a loan for a foreing property, so I was thinking to find a bank that is both in my country and in Japan, but I need to do some research on that side still.

Do I have any other options a part of my Japanese life making the loan herself?

Thanks in advance.
