Both companies had registered as of Tuesday afternoon, meeting the justice ministry’s Monday deadline, Nikkei confirmed.

Companies that do business in Japan are legally required to register not only their local arm, but also their global headquarters with authorities here. The rule is meant to make it easier to bring lawsuits against such companies over complaints in Japan, such as online abuse.

The justice ministry and the ministry of internal affairs and communications in March instructed 48 companies that fall under Japan’s telecommunications law to make the necessary filings.

The justice ministry had warned companies failing to file by Monday could lead to a fine. A total of 28 had either filed for or completed registration as of Tuesday, the ministry said.

Meta in April told Nikkei that it is “not in continuous business in Japan”, suggesting that it would not be subject to the registration requirement. The company appears to have changed its stance following discussions with the justice ministry.

TikTok, owned by China’s ByteDance, completed its registration in late July. Google and Microsoft had both registered their headquarters before the end of that month, but Meta, Twitter and others still had not. Twitter reportedly filed later.

The justice ministry will seek fines against seven companies that had failed to comply as of Monday. It had requested fines for another seven companies at the end of June, though one of them later turned in the paperwork.

The remaining companies on the list notified the communications ministry that they will cease telecom operations in Japan, meaning they would no longer be required to register there.
