I've tried to search for services that could rent japanese phone numbers just to get past the sms verification but I could not find anything that seemed legit. Some of those services work OK for some countries but japan is a lot harder to find.
Thanks for trying to help!
Japan because those services won't send the sms verification if the number is not from Japan. I contacted sms-man through their chat and asked them to add candfans a few weeks ago. They said they were going to but no news about that since then. I don't think autofications would help us there.
