Bogus Japanese Online Casino Sites Posing as Operators of MGM Osaka, Warn Officials

Osaka Prefecture and MGM Osaka Corporation each published a warning on June 8, 2026 about fake websites and advertisements that use the MGM Osaka name. Both say the sites have nothing to do with Osaka IR or MGM Osaka and may lead to online casinos. The story was reported by CasinoBeats on June 22.

What the two notices say

• Impersonation: the sites use the company name “MGM Osaka Corporation” without authorization and are not operated or managed by the company.
• Possible destination: they may be online casino solicitation sites that ask for personal or credit card details.
• MGM Osaka’s position: it does not provide, direct people to or advertise online casinos in any form.
• Official site: the company says its only official homepage is mgmosaka.co.jp.
• Legal position: Osaka Prefecture states that gambling at an online casino from within Japan is a crime and that advertising or promoting online casinos is also illegal.

The company advises people not to enter personal or financial information on suspicious sites and to report suspected fraud to the police.

What it means for players

MGM Osaka says it does not offer online casinos in any form, so a site that claims to be its online casino is not what it says it is. Check the domain against the one the company names before you type in anything, and never give card or identity details to a site you reached through an advertisement or social media message. For people in Japan the notice goes further: the prefecture says that using an online casino is itself a crime, so a warning about a fake brand is also a warning about legal exposure.
