Can I get my money back after my debit card was stolen?

My debit card was stolen yesterday, and someone used it for two transactions (about 11,000 yen total).

At the time of those transactions, I was on a train, while the payments were made at a shopping area near Osaka Umeda (HEP FIVE). I’ve already explained this to the police and filed a report.

I also submitted a loss/fraud report to Sumitomo Mitsui Bank through their online form.

Is it enough to wait for the bank’s investigation, or is it better to go to a branch in person? And how likely is reimbursement in cases like this? What else can I do in this situation? I really need my money back 😞
