Regarding the procedure for identifying the person who posted slander on the Internet and SNS, the Supreme Court ruled that the information posted by the provider before 2020 included phone numbers. Even if there is, it showed the first judgment that the phone number will also be subject to disclosure if a lawsuit is filed.

Phone numbers were not subject to disclosure until the Ministry of Internal Affairs and Communications' ministerial ordinance was revised in 2020, but a man in Chiba Prefecture and a real estate company in Tokyo said their numbers were disclosed before the revision in courts filed by them. The judgment of the two trials was divided, asking to disclose both the post and the phone number.
In the ruling on the 30th, Chief Judge Akira Ojima of the Second Petty Bench of the Supreme Court said, ``Due to advances in technology surrounding information communication and changes in the social environment, the content and scope of information regarding the identification of senders may change, so the ministry ordinance has been revised. The revision allows us to respond flexibly."
On top of that, based on the fact that transitional measures were not provided when revising the ministerial ordinance, he made a decision that ``it is possible to request disclosure of the phone number even if it was posted before the revision.'' The judgment that allowed the disclosure of information including the number has become final.
