The specific deposit methods for SBI NEOMOBILE SECURITIES are not clearly outlined in the provided information. However, based on the platform's focus on Japanese and international markets, I expect it to primarily support traditional payment methods such as bank transfers. Since the platform operates under the umbrella of SBI Securities, I assume that the deposit process will involve transferring funds from a bank account, likely in Japanese Yen (JPY), but I will need to confirm this with customer support for further clarity.
