I don't mind helping anyone that wants to verify accounts. I can only do probably three accounts. I already verified mine but I will be renting a phone. A prepaid phone costs between 5000 to 8000 yen (depending on the model)
Unfortunately due to an anti anonymous crime act, prepaid sim cards can only be purchased by Japanese residents. (Must have a proof of citizenship card)
If it only requires a Japanese e-mail address, I can can make those until kingdom come.
but if it is per phone number, we'll see how many times it will allow the same number to be used.
