yucho 通帳 online transfer help

hello!
im wondering if anyone has had an experience with this but im using my yucho 通帳 app to transfer to my friend’s mizuho bank. but i would get a notification that says:

“お申込みの送金は、外為法に基づく確認を要するものに該するため、別途ご連絡させていただく場合があります。また、1回の送金につき、3,000円の料金がかかりますが、よろしいでしょうか?
Please note that a payment fee of ¥3,000 will be charged, as confirmation in line with Foreign Exchange Law is required for your payment. Please also note that we may contact you later.”

a 3,000 yen fee is too much for a local transfer in my opinion lol any idea why? do you have suggestions for alternatives? thank you!!!!
