    JPBANK登録された電話番号をどうやって変わりますか?How do I change my JP Bank registered Phone Number?

    I recently got a JP Post Bank Account, but I now need to change my registered phone number to a different one, but I do not know how. It doesn't seem like their website is capable of changing online, because i saw no such options on the main page.... How do I change my registered phone number...
