How do I wire money to bitFlyer?

Excuse me, could you please elaborate on the process of wiring money to bitFlyer? I'm a bit new to this and would appreciate a step-by-step guide. Do I need to set up a specific account with a bank or can I use my existing one? Are there any fees associated with the transfer? Additionally, how long does it typically take for the funds to reflect in my bitFlyer account? Lastly, are there any security measures I should be aware of to ensure a smooth and secure transaction? Thank you in advance for your assistance.
