In which japanese language school should I study

I am a 20 year old next year in July my graduation will be completed.
I am planning to study in Japanese language school from October term but I’m very confused to choose the right school.
And visa problem also it says 12 lakhs should be in your account but I can only gather 10 lakhs including the fee , I’m will do part time jobs in japan so, is there any option I can pay my fees after reaching Japan.
I will do my n5 and n4 here and and I want to learn till n1 in japan in 1.3year and want to be good in conversation.
So, are there any option schools I can apply to.
Akamankia, Ala, Coto, Isi, Yamasa, japan switch schools are in my radar.
