Looking for a lawyer in Tokyo for a false debt collection situation

Hello Reddit,

I’m not sure what kind of lawyer I should be looking for, but a sim card company I ordered a sim card from and didn’t deliver in the time promised a year ago, whose services I then cancelled for that reason, has sent the costs of the contract I cancelled to a debt collection company and I was contacted by them to pay for the services opted out of.

I’m looking for a lawyer to explain the evidence (emails, etc.) to the debt collection company and get their case thrown out.

Please advise if you know a good English speaking lawyer in Tokyo.
