Airbnb Inc.'s Japan arm said Friday it was raided by authorities last month on suspicion of violating antitrust laws, but denied any wrongdoing.

Domestic media outlets had reported earlier that the company was suspected of asking property management agencies to refrain from dealing with other home-sharing platforms.

"Airbnb Japan received an on-site inspection by the Fair Trade Commission and we are cooperating with the commission's ongoing investigation," Airbnb Japan said in a statement. It said the company was the subject of an inspection that took place on Oct. 5, but added that the allegations suggested in media reports were groundless.
