I’m very happy with SBI Shinsei Bank. Just by having your salary deposited each month you can reach the silver stage, which gives unlimited ATM withdrawals and three bank transfers for free each month.
Downside is that many things which can be done online with other banks (like adding payment method to a credit card) sometimes cannot be done online, so you’ll have to fill out the paperwork.
I have Sony bank too and am also happy.
Planning to close my Mizuho and Seven Bank accounts as I’m not happy with what they offer.
